Novel approach on characterization of inter-laminar failure in glass fiber reinforced composite

Abstract

Drilling is most widely applied to composite materials; nevertheless, the damage induced by this operation may reduce drastically the component performance. A comparison between the proposed refined delamination factor (F (DR)) along with the conventional (F (D)) and adjusted (F (DA)) delamination factor is presented. The accuracy of the proposed criteria is validated using experimental results and analysis of variance (ANOVA) approach. It was found that the refined delamination factor works efficiently in the characterization of delamination failure.
