Abstract Composites comprising high‐density polyethylene (HDPE)/(soya powder)/(kenaf core) were prepared by incorporating different loads of kenaf core powder into HDPE/(soya powder) composites with an internal mixer (Haake PolyLab) for 12 min at 180°C and 50 rpm. The composition the soya used was soluble carbohydrates, 15%; insoluble oil, 18%; protein, 38%; moisture, ash, other, 14%. effect acetylation on properties investigated using a water‐absorption test, tensile thermogravimetric...

The effects of kenaf core loading and maleated polyethylene (MAPE) as a compatibilizer on processing torque, mechanical properties, water absorption were studied. HDPE/soya powder/kenaf composites prepared by incorporation powder at different loadings into matrix with an internal mixer (Haake PolyLab) 180°C 50 rpm rotor speed. A compatibilizer, i.e., MAPE, was used to improve the matrix-filler interaction properties composites. results indicated that tensile strength elongation break...

HDPE/soya powder/kenaf-core composites were prepared by incorporation of kenaf-core powder at different loadings into matrix with an internal mixer 180°C and 50 rpm rotor speed. The effects filler loading chemical treatment on properties investigated FTIR, SEM, water absorption mechanical tests. Chemical kenaf core caused a significant increase in stabilization torque, resistance the composites. Results from FTIR SEM observations indicate that better adhesion was observed for chemically...

The effects of particle sizes (range 1, 2 and 3) loading (5wt%, 10wt%, 15wt%, 20wt% 25wt %) on the mechanical properties (tensile flexural properties), water absorption morphology analysis (optical microscope) epoxy composites reinforced with cockle shell particles hybrid based composite oil palm fibres were investigated. Pre-chemical treatment alkaline solution (NaOH) 5% concentration was used to treat fibre prior fabrication composite. Based findings, smaller size lower showed higher...

The effects of chitosan on properties regenerated cellulose/chitosan (RC/Ch) films were investigated. prepared using a sequence process solution-casting in lithium chloride/N,N-dimethylacetamide ionic liquid, and coagulation water. Due to the amorphous structure formation hydrogen bonding between functional groups both components, tensile strength decreased considerably; however, elongation at break increased. Furthermore, SEM morphology indicated visible separated layers comprising rigid...

Surface treatment is one of the method used to enhance mechanical performance natural fiber composite by improving compatibility and matrix. Nevertheless, no proof can be shown on which surface absolute solution in properties composite. Different treatments might have needed for different kinds composites. In this research work, water, alkaline, permanganate, bleaching acetylation bagasse are evaluated effect soaking temperature as well loading investigated. The fiber-epoxy was studied...

Hybrid polymer composite were prepared by incorporating two indigenous agro-industrial waste reinforcements, sugarcane bagasse fiber (SBF) and coconut coir (CCF) into epoxy resin through the hand lay-up technique. Nano-silica was also added to enhance mechanical performance of materials. The alkaline treatment on surface natural fibers carried out its effects properties investigated. Generally, it is found that CCF reinforced composites exhibited higher as compared SBF composites. For hybrid...

HDPE/soy powder/kenaf biocomposites with and without compatibilizer were prepared by the incorporation of kenaf core filler at different loadings into powder an internal mixer. The specimens exposed to ultraviolet light in a weathering chamber for 500, 1000, 2000 hours scheduled water sprays simulate rain condition. effects accelerated on composite samples investigated tensile test, colour change analysis, field emission scanning electron microscopy. analysis conducted showed reductions...

During the composite’s fabrication process, one of most common defect occurs is void. Numerous literatures have suggested that presence void negatively affect its mechanical properties and effective degassing process solutions for such issue. In this study, experiments were carried out using neat E132 epoxy to investigate effects different (hot water, ultrasonic bath, vacuum) on tensile strength. The duration was from 5 – 9 minutes hot water bath where vacuum extended until 10 observed...

The incorporation of carbon nanotubes (CNTs) with polymer material has been the focus research for many years, due to relatively simple processing procedure and high potential application. However, it is found be difficult get very good CNT dispersion, viscosity built-up during CNTs dispersions. This project investigated effect resin through rheological mechanical characterization. key ingredient applied modification epoxy-CNTs properties ethanol diluent. diluent on composites was studied...
