Notes:
Tensile strength is an important material property and usually can be determinedexperimentally. The strain rate dependent behavior of T300 carbon/epoxy matrix composite wascharacterized over a wide strain rate range (10×10-5 s-1to10×104s-1). The low to moderate strain rateexperiments were carried out on a MTS machine, while the high strain rate experiment wasconducted with a split Hopkinson tensile bar. A rate dependent model was introduced to simulatethe material response. Two kinds of stacking sequence of composite specimens [(45/-45)4]s and[(0/45/90/-45)2]s were tested at different strain rates, and the results were used to determineparameters of the model. The predictions of the model showed to agree fairly well with theexperimental results. The tensile strength and initial elastic modulus of the composites increasewhen the strain rate increases
