Tensile properties of the composites were determined
using an Instron Universal Testing Machine, Model
1114, according to ASTM D412 at 500 mm/min cross
head speed. The others physical–mechanical tests were:
Crescent tear strength (ASTM D624) and hardness
(ASTM D792). Resilience was measured by using a
Wallace Dunlop Tripsometer according to BS 903: Part
A8. The angle of rebound was measured and resilience
calculated using the equation below:
