The Dynamic Compressive Properties of 3D Orthogonal Woven Composites
The high strain rate compressive properties of 3D orthogonal glass fiber woven composite were tested in through-thickness and in-plane directions by a Split Hopkinson Pressure Bar (SHPB).And the relevant quasi-static compressions were carried out in the material universal testing machine.The stress-strain plots at 3 high strain rates and quasi-static were obtained,and the fractures of the samples were observed.The results indicate that 3D orthogonal woven composite is strain rate sensitive material: its peak stress and compression modulus increase with the increase of strain rate.The 3D orthogonal woven structure makes the composite to show anisotropy: the values of peak stress and failure strain in the out-of-plane direction are higher,but compression modulus reaches higher value,and tends to be more sensitive to the change of strain rate in the in-plane direction.Compare the performances in the warp and weft direction,the composite has higher peak stress in the weft direction.
