Strain-Rate-Dependent In-Plane Compressive Properties of 3D Fine Weave Pierced C/C Composite:Failure Mechanism and Constitutive Model
文献摘要：
In-plane compression experiments are performed on 3D fine weave pierced C/C composite at a wide strain rate range of 0.0001/s-1000/s.The in-plane compressive failure mech-anism of the composite at quasi-static and high strain rates is analyzed by a scanning electron microscope.The results show that the in-plane compressive modulus,maximum stress and the corresponding strain increase with increasing strain rate.The quasi-static in-plane compressive failure mode of the 3D fine weave pierced C/C composite is characterized by the shear failure at the angle of 45° and the local buckling of the x-direction fiber bundles.In comparison,the high strain rate in-plane compression failure mode of the composite is characterized by the compres-sive fracture of the interlaminar matrix and the progressive compression failure of the x-direction fiber bundles.A strain-rate-dependent in-plane compressive constitutive model is proposed to predict the dynamic in-plane compressive response of the composite.The proposed constitutive model is verified by experimental data.
