In this work polyurethane foam composites were prepared by using kenaf core fiber as filler at different percentages. Polyurethane foam acts as the matrix and was prepared by using palm oil based polyol and isocyanate with ratio of 1:1.1. From the results obtained, composites filled with kenaf core fiber showed lower mechanical properties i.e modulus and compression strength, up to 85% decrease. However the addition of kenaf core fiber decreases the rise time of the polyurethane foam composites. SEM micrograph analysis showed the evidence of irregular cell shape with the presence of kenaf core fiber. The percentage of kenaf core fiber plays crucial role in determining the composites properties.

Compatibilizer is used to improve mechanical properties and water absorption behaviour of polypropylene/coconut fiber (PP/CF) composites by promoting strong adhesion between CF filler and PP Matrix. Maleic Anhydride Grafted Polypropylene (MAPP) treated and untreated composites were prepared in formulation of 10 wt%, 20 wt%, 30 wt%, and 40 wt%. The mechanical tensile test indicates that composite with 10 wt% has the optimum value of tensile strength, and the MAPP treated composite shows the tensile strength was increased. The modulus of elasticity was increased while the elongation at break was decreased by increasing of filler loading. Meanwhile, the swelling test discerned that the increase of filler loading increased the water absorption of composites and the presence of MAPP reduced the equilibrium water absorption percentage.

The role of activated carbon (AC) in rubber compounds was investigated to better understand the reinforcing mechanism. The activated carbon filled styrene butadiene rubber vulcanizates (SBR-AC) using bamboo activated carbon as filler were prepared by using two-roll mill and cured at 160 °C. AC filler loading from 10 to 50 phr (part per hundred rubber) were used in this study. Study into the influences of filler loading on the cure characteristics, swelling behavior, physical properties (hardness and resilience), mechanical properties (tensile properties) and morphology of SBR-AC vulcanizates were carried out. It was observed that SBR-AC vulcanizates has better cure characteristics compared to the styrene butadiene rubber gum vulcanizate (SBR-GV) which is a non-filled vulcanizate. The results showed that the scorch time (ts2) decreased with increasing filler loading. The cure time (tc90) slightly decreased up to 20 phr before a rise as the filler loading increased. The minimum torque (ML) of SBR vulcanizate increased and the maximum torque (MH) decreased up to 20 phr but then increased with increasing filler loading. The cure rate index (CRI) of SBR-GV vulcanizate was higher than that of all SBR-AC vulcanizates. Up to 20 phr of filler loading, the CRI increased before a decline occurred as the filler loading increased. As expected, the hardness value of SBR-AC vulcanizates was higher compared to SBR-GV vulcanizate which has lower resilience. The hardness and crosslink density showed an increasing trend meanwhile the resilience was adversely affected by the increase in filler loading. The tensile properties of SBR-AC vulcanizates also showed improvement in which the tensile strength and modulus at 100% elongation (M100) increased with increasing filler content. It has been proved in morphology study of the tensile fracture surfaces. Bamboo activated carbon showed some potential enhancement on the reinforcing and physical properties as well as mechanical properties of the vulcanizates.

Silane Coupling

Silane treatment used to improve mechanical properties and swelling behaviour of polypropylene/coconut fiber (PP/CF) composites by creating more adherent bonding between CF filler and PP Matrix. 3-Aminopropyltriethoxysilane (3-APE) treated and untreated composites were prepared in formulation of 10 wt%, 20 wt%, 30 wt%, and 40 wt%. The mechanical testing indicates that composite with 10 wt% has the optimum value of tensile strength, and the 3-APE treated composites shows the tensile strength was increased. By increasing of filler loading, elastic modulus was increased while the elongation at brake was decreased. Meanwhile, the swelling test discerned that the increase of filler loading increased the water absorption of composites and the presence of 3-APE reduced the equilibrium water absorption percentage.
