The influence of crystallinity on interfacial properties of carbon and SiC two‐fiber/polyetheretherketone (PEEK) composites

Abstract: The influence of the degree of crystallinity on interfacial properties in carbon and SiC two‐fiber reinforced poly(etheretherketone) (PEEK) composites was investigated by the two‐fiber fragmentation test. This method provides a direct comparison of the same matrix conditions. The tensile strength of the PEEK matrix and the interfacial shear strength (IFSS) of carbon or SiC fiber/PEEK exhibited the maximum values at around 30% crystallinity, and then showed a decline. The tensile modulus increased continuously … Show more

“…If the IFSS is too low, it is difficult to expect the performance of the fiber-reinforced composites, whereas if the IFSS is too high, crack propagation may occur (8,9). It may be necessary that IFSS should be determined by an optimization in accordance with the final purpose.…”
