Hybrid composites prepared by using oil palm empty fruit bunch (EFB) and jute fibres as reinforcement in epoxy matrix by keeping the EFB/jute fibre weight ratio constant at 1:1. In this study, effect of coupling agent on tensile and flexural properties of oil palm empty EFB/jute fibres reinforced epoxy hybrid composites evaluated. Hybrid composites are prepared by using hand lay-up technique. Particular interest is the effect of coupling agent (CA), 2-Hyroxy ethyl acrylate (HEA) on the tensile and flexural properties of hybrid composites. The laminates coupled with HEA showed better tensile and flexural properties than the one without coupling agent. The highest tensile and flexural strength value has been obtained for hybrid composite of jute/EFB/jute (CA). Tensile fracture composite specimens were analyzed by using scanning electron microscopy (SEM) to know the morphological behaviour of composites. Thermal properties of the hybrid composites were investigate to observe the effect of 2-Hyroxy ethyl acrylate (HEA) on thermal stability of hybrid composites.

The Impact

The hybrid composites were fabricated by taking cheaply available empty fruit bunch fibers and jute fibers trilayers as reinforcement in epoxy matrix using simple hand lay-up-technique. Thermal, mechanical and morphological properties were characterized. The notched izod impact strength of most hybrids increased with respect to the virgin matrix. The laminates coupled with 2-Hydoxy ethyl acrylate (HEA) showed better impact properties than the one without coupling agent. The addition of fibers and coupling agent considerably improved the thermal stability (i.e., decomposition and residue content) of the hybrids. The thermal properties measured by thermogravimetric analysis (TGA) showed that fibres and coupling agents improved thermal properties. The impact fractured composite specimens were analyzed using field emission scanning electron microscopy (FESEM) to know the morphological behaviour.

Hybrid composites were prepared by incorporating oil palm fruit bunch (OPFB) fibre in the mixture of clay and polypropylene as secondary filler. OPFB and MAPP loadings were varied to investigate it effects on the performance. Tensile and impact tests were performed on the hybrid composites to evaluate their mechanical performances. Water absorption and thermal degradation tests were also conducted on the hybrid composites. Results indicated that the incorporation of OPFB in PP/PPnanoclay has decreased the thermal stability of hybrid composites. Tensile modulus of hybrid composites increased as the OPFB loading increases and further increased with the increasing of MAPP loading. Generally the tensile strength has decreased with the addition of OPFB, however slight increased was observed when the MAPP loading was increased. The impact strength has also increased with the increasing of OPFB for higher MAPP loading.

The incorporation of materials that were formally regarded as agricultural wastes into polymeric matrix has drawn the attention of many researchers in recent years. This research focused on reinforcing high-density polyethylene (HDPE) matrix with treated jute fiber (JF)/oil palm pressed fruit fibers (OPPFF) at varying weight proportions. JF and OPPFF were cut to 2.5 mm length and were chemically treated thereafter with 1 M and 1.5 M sodium hydroxide solution respectively. The composites were produced using the compression molding technique. The morphological characterization of the fibers and composites for untreated and treated samples was studied with the aid of a scanning electron microscope (SEM). Tensile and flexural properties of the produced composite samples were also determined. From the result, the surface morphology of the fiber after treatment showed that there was obvious exposure of the fiber surface and removal of impurities as this influenced the microstructure of the composites and in turn the tensile and flexural properties. Hence, it was observed that 20 wt.% treated jute fiber addition shows the most significant enhancements in terms of tensile and flexural properties. The study exposed the effect of surface modification of JF/OPPF hybridization on HDPE matrix composite.

In this study, three types of oil palm biomass (OPB) namely, oil palm mesocarp fiber (OPMF), oil palm empty fruit bunch (OPEFB) and oil palm frond (OPF), were studied and compared as the alternative fillers in the biocomposite reinforced polypropylene (PP). The fibers were treated using the optimal condition of superheated steam treatment obtained from previous study. The OPB/PP biocomposites at weight ratio of 30:70 were fabricated by melt blending technique and hot pressed moulding. Results showed that the tensile and flexural properties of optimized-SHS-treated OPB/PP biocomposites were improved by 9 – 30% and 9 – 12%, respectively compared to the untreated OPB/PP biocomposites. The same observation was recorded for thermal stability. Improved surface morphology as shown by the tensile fracture surface indicates better interfacial adhesion between SHS-treated OPB fibers with PP matrix during blending. Overall results showed that OPF/ PP biocomposites had better properties compared to biocomposites prepared from OPMF and OPEFB, suggesting that OPF is a better OPB fiber choice as a filler in PP reinforced biocomposite.

Natural fiber-based hybrid composites with oil palm empty fruit bunches (EFB) and woven jute (Jw) fibers were prepared by hand lay-up method. Epoxy resin was used as matrix and tri-layer hybrid composites of EFB/ woven jute /EFB and woven jute /EFB/ woven jute were prepared by keeping the EFB/ woven jute fiber weight ratio constant at 4:1. The chemical resistance properties of the EFB/ woven jute/EFB and woven jute /EFB/ woven jute fiber-reinforced hybrid composites were studied by using three acids, three alkalies, and three solvents. It was found from the chemical resistance test that all the composites are resistance to various chemicals. It was observed that marked reduction in void content of composites with hybridization of oil palm EFB with woven jute fiber. Density and moisture content study demonstrated that density and moisture content property was enhanced in hybrid composites. The hybrid composites showed lower impact properties than pure EFB composite. Izod impact strength of EFB/woven jute/EFB and woven jute/EFB/woven jute hybrid was found to be 72.4 and 57.9 J/m, respectively. Impact fracture surface of the composites was studied with the help of scanning electron microscopy (SEM).
