摘要: The effect of the cooling rate on in-plane and interlaminar properties carbon fiber/semicrystalline PEEK matrix composites was studied. Strengths moduli were measured in tension, flexure, shear, all which shown to correlate, different degrees, with fiber–matrix interface adhesion bulk properties. properties, general, increased a decreasing rate, attributed changes failure mechanism from adhesive involving debonding at high rates matrix-dominant cohesive low rates. present study demonstrates that mechanical semicrystalline thermoplastic can be tailored for desired applications by controlling processing conditions, especially rate. © 2002 Wiley Periodicals, Inc.
