摘要：

This paper investigates the strain rate sensitivity of laminated composites made of plies of unidirectional basalt fibres and epoxy resin. We consider laminates with quasi-isotropic [0 degrees,-45 degrees,+45 degrees,90 degrees](s) and orthogonal [+45 degrees,-45](4) layup. A Split-Hopkinson Tension Bar is used to generate accurate stress/strain data at elevated rates of strain of approximate to 3 x 10(2)/s. Moderate strain rate effects are observed with strength increase of approximate to 3.5% per decade of increased loading rate for both laminate types.
