Abstract
Joining components of polymer composites through adhesive bonds is becoming increasingly popular. Since the strength of adhesively bonded interface is not high, the interface is designed to be of a large area in most cases. The interface of widely used adhesives like epoxy-based Epibond 1590 A/B is inherently brittle and therefore it is susceptible to fail through fracture. In this study, adhesive Epibond 1590 A/B is modified to make the interface tough by adding a small percentage of high molecular weight carboxylated acrylonitrite butadiene (XNBR). The interface is studied for four candidate proportions 0%, 5%, 7.5% and 10% of XNBR for determining toughness under static and dynamic loading conditions. Modes I and II fracture toughnesses are determined under static conditions and impact-induced damage area of the interface under impact conditions. The Epibond 1590 A/B adhesive modified with 7.5% XNBR by weight gives the best performance for the three properties studied.
