| Popis: | In this work, the effect of palm kernel shell (PKS) content on the mechanical properties of polyester resin was studied. The composites were produced by hand lay-up method with 0 vol%, 5 vol%, 10 vol%, 15 vol%, and 20 vol% concentration of 180 μm particle size PKS. The results obtained showed that the density of the composites increased with an increase in the volume fraction of PKS particles. The composite containing 15 vol% volume fraction of PKS had better compressive strength, while the addition of the PKS lowered the tensile properties of the composites. The results obtained also revealed that maximum ultimate tensile strength, yield strength, Young's modulus of PKS/polyester composites can be achieved when PKS particles are kept between 5 vol% and 10 vol% in the polymer matrix. On the other hand, for the maximum compressive strength, the PKS particles must be kept between 15 vol% and 20 vol% in the polymer matrix. This study shows that the developed composites can be used where high Young's modulus and compressive strength are required. It is suggested that PKS particles should be surface treated and investigate the mechanical properties of such composites for further improvement. |
