Abstract:

Work progress on a program to improve the interlaminar properties of fiberglass filament wound structures is reported. One of the newer epoxy resins ERLA 0400 used in the screening studies exhibited interlaminar shear strengths in excess of 15,000 psi. By winding fibers in the third planar direction, the apparent interlaminar shear strength of the NOL ring type specimens was increased by approximately 30. Although the test data were not completely conclusive, results indicated that triplanar winding increases both the ultimate compression strength and fatigue resistance of circumferentially wound cylinders.
