Laminate Tubular Specimens Subjected to Biaxial Stress States (Graphite/Epoxy).
Abstract
The responses of (90 degrees/plus or minus 30 degrees) sub s, (0 degrees/plus or minus 60 degrees) sub s, (0 degrees/plus or minus 45 degrees) sub s, and (90 degrees/plus or minus 15 degrees) sub s graphite epoxy (Courtald HTS Fibers in Fiberite-x904) Laminates subjected to biaxial stress states are presented. These results are obtained using tubular specimens with t/sub D = 0.015 and L/sub D approximately 1. Additionally included are the results of tests conducted on multidirectional flat specimens, both orthotropic and off-axis. The test results are compared with those predicted theoretically. There is reasonable agreement between analytical and experimental results.
