Abstract
Recent environmental pressures on the automotive industries to reduce carbon
dioxide emission have led to more production of fuel efficient cars. In order to
obtain good gasoline mileage, it is desired to reduce the weight of the car body.
Carbon Fiber Reinforced Plastics (CFRP) are attracting attention in the
automotive industry for their light-weight attributes. The thermoset plastics like
epoxies are mainly used as a matrix of CFRP in the automotive industry.
Nonetheless, they cannot be melted or reformed after moulding, making
recycling difficult. On the other hand, thermoplastics are recyclable, so they are
being expected to be widely applied within the industry. Polyamide 6 (PA6) is
expected to be used for the matrix of high performance composites for
automobile applications due to its good mechanical properties. Because of the
highly hygroscopic properties of PA6, the influence of water absorption on the
mechanical properties of Carbon Fiber/Polyamide 6 composites (CF/PA6) have
to be taken into account. Recently polyoxamide (PX) resin, which has excellent
durability to a water environment, has been developed. In this study, continuous
carbon fiber reinforced polyoxamide composites were molded and the influence
of water absorption on the mechanical properties of CF/PX composites has been
clarified.
Keywords: carbon fiber, thermoplastics, polyoxamide (PX), CFRTP, water
absorption.
