Abstract
Dynamic unidirectional tensile ply properties were extracted from the results of burst tests on angle ply filament wound GRP and KRP tubes under internal hoop loading. The extracted longitudinal and transverse tensile strengths as well as transverse tensile moduli exhibited strainrate sensitivities. Shear properties were derived from test results on 55 degree and 65 degree tube angles. Derived shear stress-strain curves and shear strength values are presented at different strain rates; again clearly demonstrating rate effects on these properties. Complete sets of strain rate dependent lamina tensile properties are presented for GRP and KRP covering the strain rate regime of 1 to 10 super(2) sec super(-1).
