Sandwich Construction in Glass Reinforced Plastics. Part 2. Further Beam Tests

Abstract

The report describes the continuation of an investigation into the use of sandwich construction in glass reinforced plastics (GRP) for load bearing ship structures. For these applications, the primary interest is in comparatively cheap woven cloth or woven rovings for the skins, with a variety of lightweight materials for the core. The relevant stiffness and strength characteristics of various sandwich constructions were examined by means of tests applying lateral loads to beams manufactured to typify the various sandwich constructions considered for this purpose. The constructions used 'Plasticell' and BAP 'flomat' box cores. The investigation was carried out with regard to static loading only, and effects due to fatigue, shock and high temperatures were not considered.
