Abstract
This chapter focuses on the investigation of the effects of saline environment on the properties of carbon fiber reinforced Polyether ether ketone (PEEK) and carbon fiber reinforced epoxy composites. The saline environment was controlled at various temperatures, including 37°C to simulate human body conditions. It also calculates the results of moisture absorption that were plotted against reduced time and average diffusion coefficients. The PEEK composites exhibited excellent resistance, while the epoxy composites showed moderate weight gain due to the exposure to the saline environment. The degree of crystallinity of the PEEK matrix did not seem to affect the diffusion results to a significant degree. This can help assuring good quality control at the manufacturing site. In addition, the chapter describes the mechanical properties, especially fiber/matrix interfacial characteristics, based on transverse flexural 3-point bending tests.
