Through the current study, it can be concluded that the tensile strengths of the
composites decreased when the filler loading increased. This is due to the weak
interfacial adhesion between the filler and matrix caused by the porosity and micro
cracking. Besides, the young modulus also decreased when the filler loading increased
except for the 15 wt% whereby its young modulus increased remarkably. While for the
water absorption, it appears that, as the filler loading increased, the composites tend to
absorb more water since the rice husks is known as lignocellusoic material.
