Fibre-plastic composites were fabricated using rubberwood fibres blended with polypropylene at different fibre contents (20, 40, 60 and 80 percent by weight) and fibre size fractions (less than 0.5, 0.5-1.0, 1.0-2.0 and more than 2.0 mm). The tensile strength of the composites decreased as the fibre content increased. Flexural strength tended to increase with an increase in fibre content, attaining a peak value at 40 to 60 percent fibre content. Impact strength for these composites had a maximum value at 60 percent fibre content. Hardness declined as more fibres were added into the composites. In the usage of different fibre size fractions, tensile strength decreased as fibres were getting longer. The opposite was shown for flexural strength and impact strength. Increased fibre size fractions reduced the ability to resist indention in hardness test.
