Abstract

In this study the effect of different woven linear densities on the bearing strength behaviour of glass fiber reinforced epoxy composites pinned joints is investigated experimentally. Woven fabrics with different linear densities of 200, 270, and 300 g/m2 are used as reinforcements in epoxy resin. Single-hole pin-loaded specimens of each material were tested in tension. In order to evaluate the effect of joint geometry, the ratio of the edge distance to the pin diameter (E/D), and the ratio of the specimen width to the pin diameter (W/D) were systematically varied during experiments. Failure propagation and failure type were observed on the specimens. The results show that the bearing strength of glass fiber reinforced epoxy composites pinned joints is associated with the linear densities of woven fabric, fiber volume fraction, void content, and geometric parameters. © 2009 Elsevier Ltd.
