Effect of Fiber Direction on the Instability of Single-Layer Glass-Cloth Resin-Impregnated Cylinders under Uniform Axial Compression
Abstract
The effect of direction on the instability of single-layer glass cloth resin- impregnated cylinders under uniform axial compression was studied. 108 cylinders in subgroups in which the fiber directions were 0, 30, 45 and 90 degree to the principal directions of the shell were used in the investigation. These were tested in a standard Baldwin 60,000 pound universal test machine. End shortening was measured by dial gages and load was applied at a constant but reasonably low rate. The results were statistically analyzed, and they indicate that while fiber direction is of extreme importance in questions of strength or stiffness it does not naturally influence the initial critical loads.
