Strength and stiffness of fibre-reinforced plastic plates

Strength and stiffness of fibre-reinforced plastic plates
Strength and stiffness of fibre-reinforced plastic plates
The results of tests to failure of 34 rectangular fibre-reinforced plastic panels are presented. All panels were subjected to uniform transverse pressure loading and were restrained at the edges against in-plane movement and rotation. The tests show the influence of fabrication technique, reinforcement lay-up and aspect ratio on strength and stiffness. The panels were all thin and, after initial bending, acted as membranes to carry the applied loading. It is shown that the distribution of the reinforcement is particularly influential on the stiffness and strength. The failure of the panels always occurred at the edges and was a combination of resin cracking caused by tensile stress which cut the reinforcement. The details of the failure mechanism depended on the lay-up and type of reinforcement. Possible design curves for FRP panels, based on deflection and strain parameters, are suggested.

Abstract

The results of tests to failure of 34 rectangular fibre-reinforced plastic panels are presented. All panels were subjected to uniform transverse pressure loading and were restrained at the edges against in-plane movement and rotation. The tests show the influence of fabrication technique, reinforcement lay-up and aspect ratio on strength and stiffness. The panels were all thin and, after initial bending, acted as membranes to carry the applied loading. It is shown that the distribution of the reinforcement is particularly influential on the stiffness and strength. The failure of the panels always occurred at the edges and was a combination of resin cracking caused by tensile stress which cut the reinforcement. The details of the failure mechanism depended on the lay-up and type of reinforcement. Possible design curves for FRP panels, based on deflection and strain parameters, are suggested.
