Structural Response of Various Single Lap Joint Connections for Pultruded E-Glass Fibre Rreinforced Isophtalic Polymers Composite Plates

摘要

The experimental results obtained from testing three joint configurations consisting of adhesively bonded, bolted,and hybrid joints with E-glass fibre reinforced isophthalic polyesters (GFRP) adherents are presented in this paper. The aim of this experimental program is to identify the failure modes, failure strengths and displacements for GFRP single lap joints using different joining methods. The best results have been obtained for hybrid joints manufactured by combining mechanical and adhesively bonded solutions. If compared with bolted joints, the results obtained for hybrid connections have shown an increase in the ultimate strength of 5% and 31% in comparison with adhesively bonded joints. For bolted joints with 10 Nm tightening torque, the values of the ultimate strength are 23% higher when compared with bolted joints without preloading, and approximately equal with the adhesively bonded joints
