This paper utilized the compressive tests results to examine the crushing behaviour of wood ash particles (hardwood) reinforced polypropylene (WARPP) for crash energy management. The study employed Taguchi method of experimental design to generate data for the work. Gauss – Legendre two point rules was used to evaluate the area under the stress – strain curves which measured the amount of energy absorbed per unit volume of sample. With this evaluation method the highest ultimate strength of 10.5384J/m3 with corresponding work absorption of 1.1 x 10-5J was obtained. Also established with the compression data was the specific energy absorption of 0.01038J/Kg and compressive modulus of 4.9885N/mm2.
