Effect of Fiber Direction on the Instability of Single-Layer Resin-Impregnated Glass-Cloth Cylinders under Torsion

Abstract

An experimental study of the torsional stability of single-layer open-weave glass- cloth plastic-impregnated shells is described. The design of a test apparatus and appropriate instrumentation is discussed. In all, 128 tests were made on 65 specimens for five different fiber orientations. Statistical analysis of the results showed that fiber directions affected both the torsional stiffness and buckling strength. An increase in strength due to fiber orientation was matched with a reduction in stiffness. It is demonstrated, that the Southwell method of data analysis is pertinent to the torsion problem.
