Creator:: Kimball, Kenneth Edmund and Forest Products Laboratory (U.S.)
Abstract:: This report presents the results of tests made to determine the effect of different types of configurations and notches on the tensile strength and fatigue strength of a typical epoxy laminate. Tension tests were first made of 13 groups of specimens having different forms. Based on the results of the...

Creator:: Werren, Fred and Forest Products Laboratory (U.S.)
Abstract:: This report presents the results of fatigue tests of an epoxide laminate subjected to axial loading. Direct stress tests were made at 0°, 15°, 30°, and 45° to the warp direction. Stress was applied at a frequency of 900 cycles per minute at zero mean stress on both unnotched and...

Creator:: Boller, Kenneth H. and Forest Products Laboratory (U.S.)
Abstract:: This report has been prepared as a supplement to Forest Products Laboratory Report No. 1823, "Fatigue Tests of Glass-Fabric-Base Laminates Subjected to Axial Loading." It presents a correlation of the fatigue data in the basic report with stress-rupture data on the same material reported in Forest Products Laboratory Report No....
