摘　　要：本文考察了由两种力学性能不同的基体制备的玻璃纤维、碳纤维和碳／玻混杂纤维复合材料的横向压缩性能及破坏特征，导出了估算复合材料横向压缩强度半经验公式，其估算值与实测值比较吻合。The transverse compression properties and failure features of glass fibre,carbon fibre and carbon/glass hybrid fibres composites are investigated with two epoxy resins as matrix. The fact that the experimental values of the transverse compression strength of composites are more than the theoretical values predicted by Greszczuk's formula,and Tsai's formula and Chamis' formula are examined.The results are as follows 1 . The transverse compression properties of composites rely on the properties of matrix and fibre. The transverse compression modulus is increased with matrix modulus.For the same matrix, the moduli are: GFRP>HFRP>CFRP. 2. The internal stress changement in composites under compression is diffe-rent from that under tensile, Although the transverse compression strength of composites is mainly dependent on that of matrix, it is not less than but more than the compression strength of matrix. The prediction of the transverse compression strength can not imitate the treating method of the trans-verse tensile.3.1 The semi-emprical formula of the prediction for the transverse comp-ression strength of composites is given. The predictions are in agreement with the experimental values and the formula ls identified with the pretro-spective experiment.
