Abstract: 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 the 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 show anisotropy：the values of peak stress and failure strain in the out-of-plane direction are higher，but its compression modulus reaches a higher value，and tends to be more sensitive to the change of strain rate in the in-plane direction. Comparing the performances in the warp and weft directions reveals that the composite has higher peak stress in the weft direction.
