The mechanical properties of CFRTPs made with polyetherimide (CFRTP-PEI) and polyethersulfone (CFRTP-PES) and the interfacial shear strength between CF and each polymer (CF/PES and CF/PEI) have been investigated. The relationships between measured parameters have been also discussed. The modulus and strength of both CFRTP achieved over 85% and 80% of theoretical values calculated from the rule of mixtures, respectively. For this reason, it is thought that the interfacial adhesion of CF/PES and C
An analysis method has been proposed to estimate the wear rates of fibers from the results of wear tests carried out by contacting the fiber with a rotating drum covered with abrasive paper. With this method, the influences of heat treatment, drawing and addition of aluminum borate whiskers and carbon nanotubes with cup-stuck structure on the wear resistance of polyamide 6 and poly(ethylene terephthalate) fibers have been investigated. It has been shown that the drawing of these fibers causes de
The tribological properties under abrasive wear conditions, the tensile properties, the thermal properties and the structure have been investigated on the polyamide 6 (PA6) fibers dispersed with vapor-grown carbon fibers (VGCF’s) in order to analyze the effects of dispersing VGCF’s on the wear resistance of PA6 fibers. The wear resistance of the fibers have been determined using a method previously proposed by the present authors. The coefficient of friction decreased by dispersing a small amoun
The abrasive wear rate, the coefficient of friction, and the tensile properties have been investigated on the polyamide 6 (PA6) fibers added with titanium carbide particles (TCP's), aluminum borate whiskers (ABW's) and vapor-grown carbon fibers (VGCF's). The wear rate of the fibers has been determined using a method previously proposed by the present authors. All the fillers used in this study effectively increased the wear resistance of the PA6 fiber. The effect of the fillers to increase the w
This study has focused on the recycling of carbon fiber-reinforced thermoplastics (CFRTP) based on polyethersulfone (PES) that have a high thermal stability from the viewpoint of reusing the carbon fibers (CFs). The first recycling method is the remolding of the CFRTP; i.e., the reuse of CFs through material reuse. From the viewpoint of collection, it is expected that the waste CFRTP is gathered in a shredded form. Therefore, shredded prepregs that simulate waste CFRTP were prepared, and discont
Although carbon fiber reinforced thermoplastics (CFRTPs) have attracted attention for automotive and aircraft applications because of their high production rate, there is concern that their thermal stability is inadequate even for automotive applications. However, some aromatic thermoplastics are known as polymers that have high thermal stability, so this study focuses on CFRTPs made with aromatic thermoplastics. If the CFRTPs are to be used for automotive and aircraft applications, they contrib
