Abstract

Glass Fibre Reinforced Polymer (GFRP) is a composite material, which consist of polyester thermosetting resin as matrix and glass fibres as reinforcement. Pultrusion technique is used to fabricate GFRP products in various continuous forms of structural sections such as box, I-, H-, and plates, which are similar as steel sections. The use of GFRP member in structures is relatively becoming more important especially in constructions. It was observed that the current required technical and design data of pultruded GFRP sections was rather limited especially with regard to material properties and structural performance. This study was conducted experimentally to investigate the physical and mechanical properties of the GFRP. Special observations on the effects of the fibre orientations and stacking sequences in GFRP laminates were also made. Testing procedures are basically in accordance with the requirements of the American Standard of Testing and Materials (ASTM), and the British Standard (BS). There were six different fibre orientations of GFRP plates of 6.35 mm nominal thickness employed for the test samples. They were fabricated by local manufacturer according to the commercial quality requirements. Samples were tested for physical properties, such as constituent content, hardness and density, and for mechanical properties, such as tension, compression and in-plane shear. A total of 480 GFRP samples were tested for the study. Result from the tests was reported and compiled for technical and design data at the end of the study.
