Due to the demands of environmental protection and energy saving, composites reinforced by natural fiber are highly desired in the automotive industry. In the current study, the compressive behavior and energy absorption capability of laminate composites, reinforced with flax fiber plain weave because of low-cost, resource-rich and recycling, were investigated experimentally. These testing specimens were manufactured by use of the vacuum assisted resin infusion (VARI) process and cutting operation. Experiments were conducted in a hydraulic servo test machine and a Split Hopkinson Pressure Bar (SHPB), including five different strain rates. All the experimental results exhibited good repeatability. The difference between quasi-static and dynamic compression results was analyzed. These results show that the max stress experiences an increase of 61.2% when the strain rate varies from 0.003 /s to 2800 /s. Meanwhile, more energy could be absorbed and crushing deformation transforms to shear failure when strain rate increase.
