Interlaminar Fracture Characterization : A Current Review

Abstract

Interlaminar fracture characterization has been investigated for several years. Only now is it well understood for standardization organizations to attempt to write standard test methods. This paper gives a review of the current philosophies in characterizing interlaminar fracture. The paper covers all modes of interlaminar fracture for brittle and ductile composites. First, the mode I, double cantilever beam test (DCB) for measuring G sub Ic and the end notched flexure test (ENF) for measuring G sub IIc are discussed. These tests have undergone the most extensive research throughout the years and are furthest towards standardization. In addition, the mode II, end loaded split (ELS) specimen is discussed. Mixed mode fracture is also discussed and the recently developed mixed mode bending (MMB) test is detailed. tests for evaluating mode III fracture toughness, including the split cantilever beam (SCB), are reviewed. Last, the work done on interlaminar fracture characterization in fatigue is reviewed. End notched flexure, Composite materials, Double cantilever beam, Delamination, Strain energy release rate.
