Abstract:

Carbon fibre reinforced plastics (CFRPs) can be classified according to whether the matrix is a thermoset or a thermoplastic. Thermoset-matrix composites are by tradition far more common, but thermoplastic-matrix composites are gaining in importance. There are several techniques for combining carbon fibres with a thermoplastic-matrix system. The composite’s characteristics as well as its manufacturing costs are dependent on the impregnation technique of the carbon fibre and the textile structure respectively. Carbon fibre reinforced thermoplastics (CFRTPs) are suitable for fast and economic pr

Abstract:

Carbon fiber reinforced thermoplastics (CFRTPs) have high potential in high-cycle (1 min) molding as a weight-reducing material for the mass production of automobile components. However, residual voids in CFRTPs lead to diminished and unstable mechanical properties; therefore, the effective quantification of the void content in CFRTP products is necessary for developing an affordable system for mass production. In a previous study, we demonstrated that the X-ray attenuation coefficient decreases with increasing void content; thus, measurements of X-ray attenuation coefficients can be used to e

Abstract:

There is a growing need for carbon-fiber-reinforced plastics (CFRP/CFRTP/GFRP) inthe aircraft, aerospace, and automotive industries due to their high strength-to-weightratio, high rigidity, and other features. Using these outstanding composites as machinecomponents requires machining with the desired configuration, accuracy, and surfaceintegrity. However, due to the composite structure of high-strength carbon fiber and theadhesive plastics, CFRP is difficult to machine without causing spalling or delamination,fluffing, fiber pullout, thermal degradation of the matrix resin, or other kinds of s

Abstract:

Carbon fiber reinforced thermoplastics (CFRTP) are expected to be used as a structural material for aircraft and automobiles not only for their mechanical properties such as high specific strength and high specific rigidity but also for their high recyclability and short molding time. Generally, in a composite material having a laminated structure, interlaminar delamination is often caused by an out-of-plane impact, so the interlayer property plays an important role in the mechanical properties. It has been reported that the fiber/matrix interfacial strength increases by grafting carbon nanotu

Abstract:

Carbon Fiber Reinforced Thermoplastics (CFRTP) are expected to be used in the automobile parts. Since the automobile parts can be subjected to the temperature up to 120 °C, the mechanical properties of CFRTP under high temperature environment should be evaluated. Although Polynonamethyleneterephthalaamide (PA9T) is an expected candidate as the highly heat resistant resin to be used for the matrix of CFRTP, the mechanical properties of CFRTP using PA9T under high temperature have not been clarified yet. In this study, the effects of molding conditions on the mechanical properties of CFRTP using

Abstract:

The combination of fibre-reinforced materials with metals is defined as a fibre metal laminate. These material composites have already been a subject of research for several years. The long manufacturing time resulting from the period required for consolidation of the thermosetting resin is a major disadvantage of the fibre metal laminates previously in use (for instance GLARE, which is a combination of aluminium with glass fibre-reinforced plastic). In this paper, a new fibre metal laminate with a thermoplastic resin in the carbon fibre-reinforced plastics (CFRP) is introduced. The applicatio

Abstract:

The objective of this study is to characterize damping performance of carbon-fibre reinforced interleaved toughened laminates using two types of thermoplastic-elastomer films as the interleaf materials. The damping properties of interleaved laminates depend not only on the viscoelastic properties of the interleaf films but also on the laminate sequence. The stiffness of the intra-laminar region, which can be determined by the fibre volume fraction, the elastic modulus of the fibres and the fibre arrangements, would give considerable effect on the local strain of the interleaf films and control

Abstract:

Increasing strength of epoxide resin (ER) and carbon fiber reinforced plastic (CFRP) is an aim up-to-date for many machinery sections: space, aviation, defense, automotive, and others. The aim is achieved via numerous methods of ER and carbon fiber reinforced plastic modifications. ER modifications is carried through injection of various chemical compounds. One of efficient modifications assumes introduction of plasticizers (tricresyl phosphate, oleic acid) or thermoplastics (polysulfone, polycarbonate, polystyrene, high impact polystyrene).

Abstract:

The end of life of carbon fibre-reinforced polymer (CFRP) structures represents a major challenge to the aerospace industry, as new European regulations are demanding recycling solutions that can be complicated and expensive to apply. This study aims to address new practical ways to recycle CFRP materials. CFRP materials with a polyether ether ketone (PEEK) matrix were fragmented via electrodynamical fragmentation, which exhibits several benefits compared to mechanical shredding processes, especially for composites commonly found in the aerospace industry. The fragments are characterized and r

Abstract:

3D printed neat thermoplastic polymers (TPs) and continuous fiber-reinforced thermoplastic composites (CFRTPCs) by fused filament fabrication (FFF) are becoming attractive materials for numerous applications. However, the structure of these materials exhibits interfaces at different scales, engendering non-optimal mechanical properties. The first part of the review presents a description of these interfaces and highlights the different strategies to improve interfacial bonding. The actual knowledge on the structural aspects of the thermoplastic matrix is also summarized in this contribution wi
