Evaluation and Application of GRP Composite Fasteners for Sonar Dome Components

Abstract

This paper presents a study to evaluate the mechanical properties of commercially available GRP composite fasteners for the fairing band assembly components of the hull mounted sonar domes on Canadian frigates. The study was undertaken as part of an effort to develop an all-composite fairing band assembly for a stainless steel sonar dome, to eliminate corrosion problems that occur with the use of stainless steel bolts which result in loss of the fairing band assembly at sea [ 1]. The assembly consists of two bands and a tail-cap which were changed from stainless steel to GRP composite material. The stainless steel bolts used to fasten the fairing band assembly to the mild steel ship hull were replaced with GRP fasteners to eliminate the corrosion of the mild steel structure [1]. The experimental investigations performed to evaluate commercially available GRP fasteners and the application of the bolts are presented in this paper.
