The aim of this study was to investigate the effects of compatibilising agent and surface modification of short pineapple leaf fibre on physical properties of short pineapple leaf fibre reinforced high impact polystyrene (HIPS) composites. The purpose of using the compatibilising agents in this study was to modify the HIPS which include the polystyrene-block-poly(ethylene-ran-butylene)-block-poly(styrene-graft-maleic anhydride) and poly(styrene-co-maleic anhydride). Meanwhile, the alkali treatment was also used to modify the natural fibre surface of short PALF. The results have shown that adding compatibilising agent has improved the physical properties of the composites more effectively than by only using alkali treatment to modify the natural fibre surface.

Although Natural Fibres have various potential and advantages such as lower in weight, embodied energy and toxicity but their drawbacks are provided relentless competition between natural and synthetics fibres. Intrinsically, Natural Fibres are hydrophilic that is leaded to poor resistance to moisture and incompatible to hydrophobic polymer matrix. This incompatibility of natural fibres results in poor fibre/matrix interface which in turn leads to reduce mechanical properties of the composites. This study try to litreature some methods of chemical treatment or surface modification of Natural Fibres for improving this drawback of natural fibres. The objective of this research is fungi treatment as Green Surface Treatment that is indicate to environmental friendlier process. The use of fungi can provide low cost, highly efficient and environmentally friendly alternatives to natural fibre surface treatment.

The aim of this study to investigate the physical properties of short pineapple leaf fibre (SPALF) reinforced high impact polystyrene (HIPS) composites. Three different sizes of the fibre were used in this study which was 10-40mesh, 40-60mesh and 60-80mesh. A five different fibre contents were used in this study which was 10%, 20%, 30%, 40%, and 50%. The fabricated SPALF/HIPS composites were used melt mixing and compression moulding. The physical properties of SPALF/HIPS composites such as water absorption, thickness swelling, melt flow index (MFI), and density board of composites were studied. The result showed that the addition of the SPALF was decreased the physical properties compare to pure HIPS (0% SPALF).

This paper reports the effect of alkali treatment on the mechanical properties of the natural fibre “isora” as reinforcement in unsaturated polyester resin. Isora fibre is separated from the bark of Helicteres isora plant by retting process. Properties like tensile strength, flexural strength and impact strength have been studied as a function of duration of alkali treatment and concentration of alkali. Alkalization of the fibre improves the mechanical properties of the composite. Tensile and flexural properties of the composite were found to be maximum and impact strength minimum, for an alkali treatment time of 4 hours. The mechanical properties were found to be optimum for an alkali concentration of 1%. The effects of alkali treatment on the fibre properties were investigated by SEM and IR. SEM studies were carried out to investigate the fibre surface morphology, fibre pull-out and fibre-polyester interface bonding. SEM gave evidence for the changes occurred on the fibre surface during chemical treatment.
