EXPERIMENTAL STUDY ON BOLTED JOINTS STRENGTH OF TWILL GLASS FABRIC EPOXY COMPOSITES

Abstract

Abstract:

The effect of specimen width-to-hole diameter ratio(W/D),and the ratio of edge distance to hole diameter(E/D)on the bearing strength of twill glass fabric/epoxy composites were performed experimentally.Single-hole bolted-loaded specimens were tested for their tension response.Failure propagation and failure type were observed on the specimens.The influence of the joint geometry on the strength of the bolted-loaded composites was evaluated. The experimental results show that the load capacity of glass-fabric-reinforced epoxy laminates with bolted connection increased with increasing W and E.However,the E/D ratio that is beyond 3 and the W/D ratio that is beyond 4 have an insignificant effect on the load capability of the connection.

Key words: Composite material, Bolted-joint, Bearing strength
