| Summary | Pultruded glass fiber reinforced polymer matrix composites have been tested in tension, three-point bending, four-point bending and compression. In each case, twenty identical specimens have been tested and a Weibull analysis has been conducted. The measured and Weibull-predicted ratios of bending strength to tensile strength are compared. The shape parameter and the characteristic strength for each type of loading are presented. The thickness of the composite and the angle between the pultrusion direction and the loading are two of the interesting parameters. The elastic modulus measured under different types of load is compared. Extensive measurements, such as load-deflection in bending and back-to-back strains, end-shortening, strains across the thickness in compression, have been made. |
