dc.description.abstract	The dynamic tests were carried out by using Split Hopkinson Pressure Bar (SHPB) apparatus. The test were conducted on Kenaf composite at strain rates of 872𝑠 −1 , 1003𝑠 −1 and 1594 𝑠 −1 per sec. The stress strain curves at various strain rate were plotted and discussed. Consequently, a quasi-static test on similar material were conducted on Universal Testing Machine (UTM) and the result were compared to the dynamic tests regarding to the failure mechanism. Failure of specimen from all tests were investigated using a Scanning Electron Microscope (SEM). The result for the stress-strain graph show the maximum failure stress is increasing depend on the increasing strain rate. At the dynamic compression, the failure mechanism more progressive at the higher strain rate. The initial failure mode at the dynamic loading the failure occur starting at the matrix cracking whereas at the static compression the initial debonding mode presented.	en_US
