Abstract:
Ti3Al intermetallic alloy is a hard formed material with many advantages for aviation and aerospace applications. Superplastic forming (SPF) is an ideal process for Ti3Al alloy to form sheet metal component. The thickness distribution of U cross-section circular parts, which were superplastically formed in two different female die cavity, were predicted by FEM software. According to female die forming thickness distribution, preforming die cavity was designed and was optimized by FEM software. Superplastic bugling tests with and without preforming were carried out. The thickness of parts were measured and compared with predictions by FEM software. The results showed that preforming can promote thickness uniformity efficiently in female die forming. In this experiment, the thickness difference range of the part formed with preforming reduced 75.8% compared with part formed without preforming.

Abstract:
The bamboo fiber preforming is an important process in the liquid composite molding for fabricating fiber reinforced composites with non-planar geometric shapes. This study investigated the deformation and spring back behaviors of the single bamboo fiber and bamboo fiber mat under a simple bending preforming test. The effects of the heating temperature and moisture content of bamboo fibers were studied during the tests. The result showed that the [0/90] bamboo fiber mats could be perfectly preformed without spring back after bending under the conditions of a wet and high temperature conditions. The internal structure of bamboo fiber with moisture tends to expand and soften, which makes the fibers to deform plastically under external stresses. The single bamboo fiber preforming test and stress relaxation test were conducted to study its formability. Higher heating temperature and moisture content for the bamboo fibers during preforming process can reduce the spring back effect after preforming.

Abstract:
Gas bulging with local-stretching preforming is presented to form titanium alloy tubular part with small radius. In ordinary gas bulging process, local thinning occurs at the corners with small radius and produces dangerous position of the component. In the paper, a preforming process so-called local-stretching is applied before gas bulging. Finite element simulation and experiments were carried out to verify the effectiveness of the preforming and gas bulging process for the tubular component of titanium alloy TA15. During the local-stretching preforming, the material near the corner was kept almost rigid, but the material far away from the corner experienced stretching deformation and thickness thinning. Then, during gas bulging, the material near the corner experienced thinning deformation. So, the thickness uniformity of the final component was improved effectively.

Abstract:
Both the minimum relative depth of die cavity and the minimum amount required in preforming are determined to produce a defect-free product of tubular component in the preforming technique of radial extrusion in this study. This scheme is based on the least amount of material dissipation in radial extrusion of tubular component. A finite element based code is utilized to investigate the effects of various relative depths of die cavity, different percentage of preforming and relative height reduction on the material flow characteristics resulting in the movements of the defects locations. The abductive network is also applied to synthesize the data sets obtained from the numerical simulations. Consequently, a prediction model is established for organizing the minimum relative depth of die cavity and the related minimum amount required in preforming of the tubular component for different end strokes of deformation.

Abstract:
The preforming stage in hydroforming of an aerospace generic shape was investigated using a combination of experimentation and numerical modeling. The preform die was manufactured using a rapid prototyping method, namely the selective laser sintering (SLS) process. The preforming experiments were conducted on 0.9 mm and 1.2 mm thick stainless steel 321 (SS321) tubes. To evaluate the preforming process, an automated deformation measurement system, ARGUS®, was used to measure the 3-dimensional (3D) strains on the deformed tubes. Data collected from the experiments were used to validate the simulation of the preforming stage. The simulation and experimental results were found to be in good agreement, indicating that the preform model can be used as a starting point for simulating the tube hydroforming (THF) process. In addition, the SLS approach was found to be very promising, as it reduced greatly the lead time and cost of process development for THF.

Abstract:
Discontinuous fibre composites are under increasing investigation for structural and semi-structural components as they are easily automated, making it possible to remove costly hand labour based steps typically associated with advanced fibre reinforced composites. Directed fibre preforming (DFP) is one possible process which has several advantages when compared with competing techniques. Low material and process costs coupled with short cycle times means the process is suited to medium volume production (typically <10,000 ppa). Predicting mechanical performance remains a major obstacle to industrial adoption however, due to the stochastic nature of fibre distribution. This is of particular importance for structural applications where minimum property requirements and a greater certainty of performance must be achieved. This thesis employs a stochastic macroscale modelling approach to predict fibre locations during the reinforcement deposition stage. This is achieved through process characterisation studying the effects of key microstructural and process-specific parameters on fibre distribution and orientation. The proposed DFP simulation software can generate realistic fibre networks for complex three-dimensional component geometries providing feedback on preform quality. This information is used to optimise the preform structure via process input parameters such as robot trajectory and material properties with validation tests conducted to assess model accuracy. An interface between the simulation software and commercial finite element code facilitates mechanical property analysis for full-scale components using realistic load cases. The complete software package is intended to streamline the route to manufacture for DFP processes from a conceptual design stage.

Abstract:
Significant proportion of composite industry is currently produced using prepregs, cured in autoclave which is very expensive and time consuming process. Dry textile preforms in conjunction with liquid molding techniques can lead to significant reductions in material costs, manufacturing costs and cycle times. These dry preforms are typically 2D woven or braided fabrics which also required lay-up and have low interlaminar properties. Through thickness reinforcement provides solution for this problem as it gives better interlaminar properties as well as near net shape performing. Various 3D performing methods are discussed and reviewed in this research where 3D weaving comes out as ideal process to develop near net shape preforms with more efficiency and better material performance. This research highlights the advantages and limitations of conventional 3D weaving processes. A number of approaches for improving the flexibility of 3D weaving process have been presented including changing fiber architecture in different sections of the preform, tapering in the width and thickness directions and finally to change the fiber orientation. It is concluded that multi step and taper fabrics can be produced on conventional weaving by some modifications. Furthermore, a novel 3D weaving machine is designed and developed after reviewing various patents and weaving methods to overcome limitations of conventional weaving machine. Key criterions from limitations of conventional weaving processes are considered and modified such as multiple weft insertion, limited warp stuffer movement, linear take-up to develop 3D weaving machine. In order to achieve isotropic material, two textile technologies are combined to get final requirements. 3D weaving can provide us fibres in 0° and 90° direction with through thickness reinforcement, whereas braiding can satisfy the requirement of bias direction fibres. Near net shape preforms such as taper and multistep are produced and laminated. Preliminary testing is performed on these laminates to evaluate fibre architectures. Further work is required in terms of machine modification which can provide weave design flexibility to explore various multilayer weave architectures. Thorough testing is required to evaluate and define structure performance and effect of fibre damage during weaving process.

Abstract:
Fibre Reinforced Plastics offer several advantages over other materials such as decreased part counts, weight savings, and flexibility. The obstacles to the further expansion of composites use, particularly in cost-conscious industries such as the car industry, include volume, cost, and quality. Liquid Composite Moulding, where the dry textile reinforcement is shaped prior to application of the plastic matrix, offers to address these drivers by offering potential for automation, speed, and quality control. However, the preforming of the dry reinforcement is rarely automated, and its results are variable and hard to predict or control. This thesis aims to facilitate better preforming process design and control. The dominant deformation mechanism that allows reinforcements to conform to a 3D surface is trellis shear. Work is therefore presented on shear characterisation of textile reinforcements using the picture frame and the bias extension tests. Several approaches to normalising these tests to achieve method-independent shear data are proposed, and compared. Of these, a normalisation technique for the bias extension test based on energy considerations appears to be the most appropriate. A constitutive modelling approach, based on the meso-mechanical deformation mechanisms identified in the reinforcement, is developed for characterising the asymmetric shear properties exhibited by non-crimp fabrics. The results from this model are compared with experimental data. Finally, an energy minimising kinematic drape method is developed to account for the use of automated reinforcement blank-holders, and methods for modelling process variability using the code are investigated.

Abstract:
Carbon fiber composites have received growing attention because of their high performance. One economic method to manufacturing the composite parts is the sequence of forming followed by the compression molding process. In this sequence, the preforming procedure forms the prepreg, which is the composite with the uncured resin, to the product geometry while the molding process cures the resin. Slip between different prepreg layers is observed in the preforming step and this paper reports a method to characterize the properties of the interaction between different prepreg layers, which is critical to predictive modeling and design optimization. An experimental setup was established to evaluate the interactions at various industrial production conditions. The experimental results were analyzed for an in-depth understanding about how the temperature, the relative sliding speed, and the fiber orientation affect the tangential interaction between two prepreg layers. The interaction factors measured from these experiments will be implemented in the computational preforming program.

Abstract:
A novel sheet metal forming technology based on aspects of both warm forming and superplastic forming has recently been developed. The new forming process, referred to as hot draw mechanical preforming (HDMP), uses two sequential steps to form a panel within a single tool at elevated temperature. In the first step, the cushion system acts on a binder and upper die to draw the blank over a punch which serves to draw in metal from the perimeter of the blank. In the second step gas pressure is applied to finish the panel details. This two step process of drawing in metal followed by gas forming can result in a significant expansion of the forming envelope for conventional AA5xxx series aluminum sheet alloys commonly used within the automotive industry. Similar to SPF, the HDMP process is performed within a single forming press equipped with heated platens and using gas pressure to shape the component during elevated temperature forming. However, the HDMP process utilizes a blankholder to control the flow of material into the forming cavity during the drawing stage and therefore requires the addition of an integrated cushion system in the bed of the press. HDMP dies are of interest in automotive applications because they maintain the low-investment attributes of SPF tooling while also significantly reducing the forming time as compared to conventional SPF. This work details the CAE based design of an HDMP die to form a one-piece aluminum door inner that can not be formed with conventionally forming processes. Critical aspects addressed in the development of the die include manufacturing targets, part design for manufacturing, and die design for operation at elevated temperature.

Abstract:
Abstract This paper offers an alternative solution in dealing with Focused Ion Beam (FIB) circuit edit debug of RF products that often required soldering the device onto a test board to enable sensitive RF characterization. Performing FIB circuit edit while the device is soldered on a test board not only eliminates signal degradation and inconsistency caused by a socket; but also, it allows for adding additional FIB edits on the same device. The conventional way of RF product debug of devices in a wire bond package was to characterize the device in a socket, perform the FIB circuit edit, encapsulate the cavity to protect the device from physical & thermal damage, solder the device onto the test board, and then perform post-FIB characterization. This is a very long, one-way process and needs multiple devices for design debug. For RF products in flip chip package, this approach was extremely difficult to almost impossible, because thermal stress of soldering device would significantly deform thinned die. All characterization had to be done with a socket, which often introduced changes of the same magnitude of the parameters of interest as well as repeatability issues. The purpose of this paper is to outline steps to allow for the RF FIB and characterization cycle to be done in a way to decrease throughput time and increase measurement accuracy. True characterization of highly sensitive RF circuit modifications is achieved through: soldering the device to the test board, performing sample preparation, preforming pre-FIB characterization, preforming FIB, and finally preforming post FIB characterization. Elimination of the need to solder a thinned device to a test board allows for the edit location to remain open enabling additional FIB edits to be performed on the same device. This eliminates redundant steps in the device sample preparation and enables quicker throughput times.
