In this study, Jute fibers reinforced polypropylene (JFRP) composites were manufactured by injection molding technique. Prior to fabrication of composites, fiber surface was treated by Alkali and Plasma for a rise in fibers properties. Furthermore, after the alkali treatment attempt plasma treatment for the fiber surface treatment to obtain a batter value. In order to improve the affinity and adhesion between fibers and thermoplastic matrices during manufacturing, Maleic anhydride (MA) as a coupling agent have been employed. Untreated and treated surfaces of jute fibers were characterized using SEM. Tensile and flexural tests were carried out to evaluate the composite mechanical properties. Tensile test indicated that 3% of the alkali treatment and 2min plasma treatment fiber has highest tensile strength.

Fiber Surface Treatment

Morphology, mechanical properties and rheological behavior of wood plastic composite, derived from acrylate-styrene-acrylonitrile (ASA) and bagasse which was treated with potassium permanganate (KMnO4) and using styrene butadiene rubber (SBR) as impact modifier, were reported. The effect of fiber surface treatment with KMnO4 and different amount of SBR on properties of wood plastic composite, prepared from ASA and 50 phr of bagasse, were investigated. Wood plastic composites (both treated and untreated) with varying amount of SBR, as impact modifier from 0-15 wt% of ASA, were prepared by melt-blending technique. The specimens were shaped with a compression molding machine and characterized, including morphology, impact strength, flexural properties and rheological behavior. It was demonstrated that the fiber surface treatment, using KMnO4, could effectively impove interfacial adhesion between bagasse and ASA matrix. These led to an improvement of morphology and mechanical properties such as impact strength, flexural strength and modulus. SEM micrographs revealed that the interfacial modification enhanced the interfacial adhesion between bagasse (fiber) and ASA (matrix) causing an increasing of shear stress and shear viscosity. Additionally, the effect of amount of SBR, as impact modifier, was also reported. The resulted showed that the impact strength was improved with increasing the amount of SBR (up 5 wt% of ASA) whereas, flexural strength and modulus were found to decrease with increasing SBR content.

Abstract Oil palm fibers have been developed as reinforcement in the composite. These fibers can be produced from fruit, trunk, and frond of oil palm. In this review, the oil palm fruit fiber for reinforcing composite was focused. Oil palm fruit fibers consist of empty fruit bunch (EFB) and mesocarp fruit (MF) fibers. The chemical composition and characteristics of oil palm fruit fiber are described. Furthermore, the mechanical properties of the composite are reported to be related to the surface treatment of EFB and MF fibers. Applications of such fiber composite are included in this review. From some researches, the surface treatment methods for MF and EFB fibers as reinforcement composite was conducted with using alkali, silane, acryilic acid, acetic anhydride, hydogen peroxide, microwave, and superheated steam. The effect of these surface treatments on oil palm EFB and MF fibers displayed the improvement of the mechanical properties (tensile, flexural and impact strengths) of the composite due to enhance the interface adhesion between fiber and matrix after treatment of fibers.

The paper investigates the processes of carbon fiber surface treatment and their influence on the properties of polyetheretherketone composites. It has been shown that preliminary thermal activation of carbon fiber followed by treatment with a dressing agent - polyhydroxyether makes it possible to create polyetheretherketone composite carbon-filled materials with an increased level of physical and mechanical properties.
