The hybrid composites prepared were subjected to water immersion for 14 days to see how this concept can affect water uptake. At equal percentage ratio of the fibres, hybridization effect was optimized for tensile and flexural test; however, K6P4 gave the optimum impact strength while K3P7 resulted in the least overall water uptake.
Strength and modulus values increased with increase in percentage of pineapple leaf fibre in the composite and the higher aspect ratio of kenaf helped in the dispersion of matrix in the composite.
Favorable balance between the inherent advantages and disadvantages of these two fibres complemented each other. While pineapple leaf fibre helped the composite in tensile and flexural properties, kenaf provided impact strength and in reduction of water uptake.
Dependence of modulus on the percentage of cellulose in natural fibres was clear.
Kenaf and pineapple leaf fibre offered tremendous potential for hybridization. SEM was used to describe this interesting phenomenon. Mechanical properties of naturally weight reduction in composites. Generally, two components can also be predicted by the rule of their elongation at break are comparable, which mixtures, that is19 means when combined for the preparation of compos- ite, they can synergistically transfer stress with each other without catastrophic failure of the product.
However, Downloaded from jcm. Physical properties of kenaf and pineapple leaf fibre PALF. Kenaf, though grade high density polyethylene also purchased from also hydrophilic, is expected to help lower the resulting KEFI Malaysia.
The Brabender was preheated composites are presented. Impact samples were subsequently notched. It was Mechanical property testing. Notched Izoid mathematically as: Water absorption test was conducted at day 1.
Their percentage weight increase was measured properties exhibited by the hybrid. K- denotes kenaf, after every 24 h, which represents their percentage P- PALF while the numbers shows the respective pro- water uptake for that duration.

Abstract. Cellulose whiskers were isolated from kenaf (Hibiscus cannabinus L.) bast fibers via sulfuric acid and hydrochloric acid hydrolysis. Raw kenaf bast, NaOH treated, bleached fibers, sulfuric acid whiskers (SAW) and hydrochloric acid whiskers (HClW) morphology, functional groups, crystallinity, and thermal stability were characterized.
The purpose of this study is to clone and characterize the expression pattern of a F5H gene encoding ferulate 5-hydroxylase in the phenylpropanoid pathway from kenaf (Hibiscus cannabinus L.).Kenaf is a fast-growing dicotyledonous plant valued for its biomass. This study has showed that the sorption of crude oil on kenaf (Hibiscus cannabinus L.) plant parts is particle diffusion controlled.
The rate coefficient for particle diffusion were and mm -1 for the root parts and stem parts, respectively. At g/cm3, its oil sorption capacities were 36, 43 and 45g/g for diesel, ASW46 and HD40, respectively.
The values decreased to , and g/g at g/cm3. Its sorption capacities for the three oils were significantly higher than those of PP.
