Abstract

The limited length of pultruded plank sections requires them to be adhesively bonded for composite marine structures, using butt joint. However, the nature of materials and moulding process present limitations to the efficiency of the double-strap lap shear (butt) joints. This requires the composite make-up at the joint location to be tailored for adhesion. In this case, pultruded strips moulded from unidirectional glass rovings and polyester resin are coated with a low viscosity epoxy resin prior to bonding. The resin coating together with the replacement of bonding straps material resulted in a significant strength of the butt joints. The paper presents the experimental and numerical details and results and outlines the future work.
