The Adhesive Bonding of Thermoplastic Composites

Abstract

After treating the composites corona discharge treatment, the crack ran either in the adhesive in a cohesive mode or in the composite in an interlaminar mode. To understand these two types of crack propagation, various techniques have been adopted. Failure stresses of the composites have been quantified using butt joints and these values have been compared with finite element analysis (FEA) predictions. There was good correlation between the two sets of data, i.e. when the stress in the composite predicted from FEA was higher than the measured failure stress from a butt joint experiment the crack propagated in the composite.
