Characterization of Delamination in Advanced Composite Materials Under Mode III Loading Conditions

Abstract

Delamination is the weakest and major failure mode in laminated fiber reinforced composite materials. Delamination is also a fundamental issue in the evaluation of laminated composite structures for durability and damage tolerance. This study involved the characterization of mode III delamination primarily using the mode III split cantilever beam specimen. The effects of altering four test parameters on the cantilever beam test specimen. This evaluation thickness on the mode III critical strain energy release value, investigation of altering crosshead rate on the mode III critical strain energy release rate, the effect of temperature on the mode III critical strain energy release rate, and the addition and subtraction of a mode I component on the critical strain energy release rate. For comparison, a few double split cantilever plate specimens were also tested.
