Abstract : The effects of increasing the rate of loading on the tensile properties of glass-reinforced plastics of various types were studied and compared. The rates investigated were the conventional, or static, which produces failure in approximately 2 minutes, and the high rate, which produces failure in approximately 6 milliseconds. The materials studied were polyester laminates containing different types of glass reinforcing material. The effects of the direction of the reinforcing material on the tensile properties were investigated. Changes in the interlaminar shear properties due to changes in the loading rate are discussed.
