EFFECT OF WAVINESS DEFECT ON COMPRESSIVE BEHAVIOR OF COMPOSITE LAMINATES

Abstract

Abstract: We adopted VARI process and the autoclave molding process to manufacture compression samples with different reinforced fibers and compression samples with fiber waviness defect. The results of the compression tests showed that Young's modulus and compressive strength degraded seriously with the increase of fiber waviness ratio, and fiber waviness had greater influence on compressive strength. Meanwhile, uniform waviness had a greater effect on compressive strength and Young's modulus than graded waviness. Interlaminar shear stress was found to be the dominant failure mechanism. Moreover,the samples are prone to have transverse shear failure on the position of maximum misalignment angle.

Key words: defects, waviness ratio, interlaminar shear failure, fiber off-axis angle
