Natural fibers, in particularly lignocellulosic fibers are attracting material scientists now days, due to their comparative advantages over synthetic fibers. Biodegradable composites reinforced with short banana fibre after alkali treatment along with cassava starch matrix were prepared using the hot compression method. The mechanical properties like tensile strength and impact strength were investigated. Mechanical properties of the composites made from alkali treated fibres were superior to the untreated fibres. SEM observations on the fracture surface of composites showed that the surface modification of the fibre occurred and improved fibre–matrix adhesion.

Abstract Surface modification of natural fiber may greatly enhance the mechanical interlocking between fiber and matrix. Although there are many reports on surface modification of natural fibers, little technical information is available to enable the selection of optimized surface modification conditions. In this work, treatment parameters, such as bath temperature, agent concentration, and treatment time, are optimized to achieve higher interfacial adhesion. The effect of these parameters on flexural and impact strength is investigated by applying gray relational techniques. Experimental results show that NaOH concentration and treatment time are significant variables which improve interfacial strength, while NaOH bath temperature appears less important.

This work presents the physical-thermal and mechanical characterization of a low-density polyethylene (LDPE)-Al matrix composite material that was obtained from reinforcing recycled (post-consumer) long-life Tetra Pak packages with fique natural fibers from southwestern Colombia. The fique was subjected to three chemical treatments to modify its surface (alkalinization, silanization and pre-impregnation with polyethylene) to increase the quality of its interfaces. Additionally, panels with 10%, 20%, and 30% v/v of fiber were manufactured by the hot compression molding. The mechanical properties of the different composite materials showed that the pre-impregnation treatment promoted a significant increase in the tensile and flexural properties with respect to the fiber-reinforced composite without surface modification. Additionally, in materials with 30% fibers that were treated with pre-impregnation, there was a decrease in the water absorption capacity of 53.15% when compared to composites made with 30% native fibers. Finally, increases in the fiber content mainly caused better mechanical performances, which increased as a direct function of the amount of fique incorporated.

Utilization of locally abundant agro-waste Alpinia galanga (A. galanga) natural fibers in polyethylene (PE) was investigated. The results indicate that agro-waste fibers generally function as potential natural-organic fillers as well as show an attribute of reinforcement in PE-agro-waste composites at a certain fiber loading. Minimally reduced tensile strength from 28 MPa of unfilled PE, addition of agro-waste A. galanga natural fibers also resulted in reinforcement of up to 31 MPa at 6 wt% agro-waste fibers loading. Findings also reveal that alkali treatment was effective to impart surface modification of agro-waste A. galanga natural fibers and hence improved tensile strength, modulus of elasticity and thermal stability of PE-agro-waste composites.
