Study of experimental investigation of tensile compress and in-plane shear properties dispersibility of composite laminate

For fiber reinforced T300/QY8911 composite laminate, the tensile, compress and in-plane shear experiments were carried out to get main mechanical characters. The strength and rigidity characters of the fiber reinforced composites are studied and found that the stress-strain relations of tension compression and shear are almost linear, specimen's failure is abrupt. The distribution properties of the mechanical characters are also studied with the method of statistical analysis. The result of the statistical analysis shows that 3-parameter weibull distribution, Normal distribution and lognormal distribution are good functions to describe the distribution properties of the mechanical characters. Finally, the parameters of the dispersibility of the tensile compress and shear properties of composite laminate are given.
