| Summary: | The study on the effect of cane wood and palm kernel as filler materials on the compressive strength and density of an automobile brake pad has been done. The Central Composite Design tool of the Design Expert 8 software was used to design percentage composition of the test samples for 20 experimental runs. To ascertain how well the factors fit in the design, the lack of fit test was performed. The analysis of variance shows that the developed models are significant and quadratic, showing that both materials affect the responses. On optimization, optimal compressive strength and density of 107.3 MPa and 1.73 g/cm 3 were obtained for the composition of 30% resin content, 21.329% palm kernel fibre content and 40% cane wood content. Thus, the combination of cane wood and palm kernel fibre as filler material for brake pad production will give an automobile brake pad with good compressive strength and density.
