Load-carrying capacity of filament-wound E glass/epoxy composite rings

Abstract

In this study, three different types of E glass/epoxy composite rings were produced by the filament-winding technique: (i) O ring (Type A), (ii) ring with a radial notch (Type B), and (iii) C-shaped ring (Type C). To evaluate the effect of winding angle on the load-carrying capacity of composite rings, five different winding angles were considered: ±45°, ±55°, ±65°, ±75°, and ±88°. The load capacity of the manufactured composite rings in the tensile hoop direction were determined experimentally using a special test fixture. The experimental results showed that the optimum winding angle was ±88° in terms of load-carrying capacity. The rings wound at 55° had the lowest load-carrying capacity. Type A rings had the highest capacity while Type C rings had the lowest.
