Abstract
Interlaminar delamination is an important problem in applications of carbon fiber reinforced composites. Delamination occurs due to the presence of matrix cracks, causes fiber breakage, and results in the loss of stiffness and strength, which may lead to safety and reliability problems. In this study, the effect of polyethersulfone (PES) of the epoxy resin on interlaminar shear strength and fracture toughness of carbon/epoxy composites was investigated. Consequently, interlaminar bonding increased with proper addition of PES, but excess PES led to loss of interlaminar bonding of the carbon/epoxy composite.
