Abstract:

Following an extensive literature survey focusing on the machinability of carbon fibre reinforced plastics (CFRP), three main phases of experimental work were undertaken to evaluate the drilling of CFRP and associated stack materials. Phase 1 and 2 involved small diameter holes (1.5 mm) in thin CFRP laminates (3 mm thick) while Phase 3 addressed the feasibility of one-shot drilling (6.35 mm diameter holes) in multilayer workpiece stacks comprising titanium, CFRP and aluminium. Machinability was assessed in terms of tool life/wear, force/torque, hole size and geometrical accuracy, workpiece sur

Medical diagnosis and treatment of critically ill patients require frequent monitoring of carbon dioxide partial pressure in the human body.

Abstract:

The research relates to a study on the routing/slotting of CFRP composites of the type used in aerospace applications. Following a literature review, 3 phases of experimental work were undertaken to evaluate the effects of key process variables on the machinability of CFRP. The influence of varying operating parameters, tool material and cutting environment were initially investigated in Phase 1 work. The results showed that use of PCD was critical and highlighted the importance of chilled air in maintaining adequate tool life and acceptable workpiece integrity. Delivery of chilled air through

Abstract:

Carbon composites, particularly carbon fiber reinforced plastics (CFRPs) are increasingly being used in many commercial applications such as automobile, aerospace, and civil infrastructures. This increase in the demand of CFRPs has led the manufacturers to research for ways of early detection and classification of defects in CFRP. This thesis work discusses the implementation of a Hopfield neural network (HNN) to automatically detect and classify defects in CFRP by ultrasonic testing (UT). Three of the most common and critical defects found in CFRP, i.e. foreign object (FO) inclusion, impact d

Abstract:

Single walled carbon nanotubes (SWNTs) have been successfully employed in a wide range of large-area and low-cost optoelectronic devices, such as field-effect transistors (FETs), light emitting diodes, solar cells, and logic circuits. Most common synthesis methods produce a mixture of nanotube diameters that typically results in one-third of the as-synthesized nanotubes being metallic and the remaining two-thirds being semiconducting. These synthesis procedures have a big impact on many optoelectronic applications, where the presence of metallic SWNTs could dramatically degrade device performa

The use of carbon fibre reinforced plastic (CFRP) and metal matrix composites (MMC) is steadily increasing as an alternative to traditional metallic materials in various industrial sectors. The overall aim of the project is to assess the machinability when drilling epoxy based CFRP and Al/SiCp MMC composites and understand its effects on feature quality and workpiece integrity.

Abstract:

The mixing of additives into a plastic is an extremely important step in the plastics industry, necessary for the manufacture of almost every conceivable product. Therefore the costs in developing new products can prove very expensive as the testing is usually carried out using full scale machines, usually using twin screw extruders because they are able to provide good dispersive and distributive mixing. This is particularly important when compounding difficult to disperse additives and nano-additives. What is required is a machine that can replicate the mixing abilities of a twin-screw extru

This thesis provides new methodologies to improve the simulation of the orthogonal cutting of unidirectional carbon fibre reinforced plastic (UD-CFRP) composites. In a meso-scale approach, a new cohesive model was developed to overcome the excessive deformations shown by the generally implemented zero thickness cohesive elements. The smoothed particle hydrodynamics (SPH) approach was implemented to avoid element deletion during the analysis, taking place in the commonly used finite element method (FEM). The SPH enabled better prediction of the thrust force, more realistic chip formation mechan

Aircraft disasters during take-off and landing by the impact of foreign object debris (FOD) have always been an important issue. When the wing is lifted, its upper and bottom surfaces are subjected to compressive and tensile stresses, respectively. The bottom surface of the aircraft wing is vulnerable due to the threat of runway debris, which may travel at high speed, leading to the catastrophic failure of structures under tension.

There is a drive for modem engineering structures to exploit the excellent specific properties of advanced fibre reinforced composite materials, particularly in aerospace, where manufacturers are under intense pressure to reduce costs and engineer lighter more efficient aircraft. However it is widely recognised that the susceptibility of these materials to transverse impact damage is restricting the extent to which these benefits can be exploited.

Abstract:

Cílem této diplomové práce je lépe porozumět konceptu únavového poškození damage tolerance zmapováním všech možných vlivů na lomovou houževnatost vláknového kompozitu s polymerní matricí. Toho je dosaženo provedením zkoušek za různých podmínek (např. změna parametrů měření, mód zatížení, pořadí vrstev a materiál) a monitorováním odlišností v šíření trhliny. Na základě dat získaných během těchto testů je určena lomová houževnatost. Potenciální rozdíly jsou zkonzultovány a porovnány s ostatními vzorky.

Abstract:

Non-conventional techniques for polymerization and depolymerization were investigated. The rates of polymerization were enhanced higher in ultrasonic, supercritical fluids and microwaves. However in these system under certain conditions, simultaneous degradation also occurred. Depolymerization was studied by various methods like thermal degradation in supercritical fluids and in presence of oxidizers, Lewis acid and other organic acids. Degradation by ultrasound and thermal degradation of polymer mixtures were also investigated. The scission of the polymer backbone is random for thermal degrad
