Renewable resourced green biocomposites are currently receiving much attention due to their environmental advantages. Therefore, the aim of this research is study the effect of fiber surface treatment on the mechanical properties of polylactic acid (PLA) biocomposite in order to produce a green biocomposite. Experiments were conducted by surface treatment of empty fruit bunch fiber using two methods, sodium hydroxide and silane. Both treated and untreated fibers were then melt compounded with PLA and mechanical properties of the biocomposite was studied. The results showed that silane treatment improved the reinforced biocomposite mechanical properties such as tensile strength by 33% and flexural modulus by 44% compared with untreated fiber reinforced biocomposites. This is due to the silane functional groups that act as a bridge between the PLA and fiber.

Fiber Surface Treatment

Biodegradable plastic reinforced natural fiber composites are finding applications in many fields ranging from construction industry to food industry. The use of natural bio based fillers as reinforcements in composites has several advantages over inorganic fillers including lower density, renewability, and biodegradability. In this research, polylactic acid (PLA)/ microcrystalline cellulose (MCC) composites were investigated as a means to reduce the material cost and enhance the material properties. The coir fibers were used to prepare microcrystalline. Subsequently, the prepared MCC was treated with 3-amiopropyl triethoxysilane (APS) to improve interfacial adhesion between fiber and polymer matrix. Treated and untreated MCC were then mixed at 0-10 wt.% with PLA by twin-screw extruder and fabricated into test specimens by compression molding. The effects of MCC loading and surface treatment on morphology, mechanical properties, and thermal properties of PLA/MCC composites were investigated. The results showed that the PLA with 5 wt.% of MCC exhibited the best mechanical properties compared with all prepared composites. Thermal stability of PLA composites were decreased with increasing MCC content but it can be improved by treated the MCC with APS.

Fiber Surface Treatment

AbstractIn this work, the influence of carbon fiber surface treatment on mechanical properties of unsaturated polyester was investigated. Two approaches have been used in the surface treatment; the first is the desizing of the carbon fiber by the release of the epoxy layer. The second is with the release of epoxy layer and etching the fibers. It was concluded that both methods give good results on adhesion between the matrix and the fibers. It is found that the treatment of carbon fibers is efficient and greatly improves the CFRP handress. The tensile strength of composite materials increases by 30% for etched carbon fibers compared to untreated carbon fibers.SEM images confirm the results obtained.

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.

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.
