摘要: Abstract In this paper the effect of strain rate on tensile, shear and compression behaviour a commingled E-glass/polypropylene woven fabric composite over range 10−3–102 s−1 is reported. The quasi-static tests were conducted an electro-mechanical universal test machine modified instrumented falling weight drop tower was used for high characterisation. tensile modulus strength increased with increasing rate. However, seen to decrease Strain constants use in finite element analyses are derived from data. observed failure mechanisms deduced microscopic study fractured specimens presented.
