Polymeric materials reinforced with synthetic fibers like glass, carbon, and aramid provide advantage of high stiffness and strength to weight ratio as compared to conventional materials like wood, concrete etc. Despite of these favours modern researches are going on in the field of natural composites because of low initial cost and availability of ease. I the light of these the present experim...

Fiber matrix adhesion was promoted by hybrid fiber composite surface modifications using an alkaline treatment. However, it was found that the resulting strength and stiffness of the composite. The elastic modulus of the composite did not improve with the fiber surface modification. A notable disadvantage of natural fibers is their polarity which makes it incompatible with hydrophobic matrix. T...

ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(pan)-based carbon fiber. the surface characteristics of carbon fibers were characterized by x-ray photoelectron spectroscopy (xps). the interfacial properties of carbon fiber reinforced polyamide 6 (cf/pa6) composites were investigated by means of the single fiber pull-out tests. as a result, it...

In this study, six combinations of flax, hemp, and glass fiber were investigated for a hybrid reinforcement system in a polyurethane (PU) composite. The natural fibers were combined with glass fibers in a PU composite in order to achieve a better mechanical reinforcement in the composite material. The effect of fiber hybridization in PU composites was evaluated through physical and mechanical p...

In this study, carbon nano fibers (CNFs) were mixed into epoxy resin through a magnetic stirrer and again mixed using ultra sonicator. Using hand layup technique, biaxial braided fiber composites were prepared with unfilled, 0.2, 0.5 and 1 wt% CNF. Tensile test and shear test was performed to identify the tensile strength and shear strength of the composites. Fractured surface of the tensile sp...

The popularity of composite materials usage is increasing due to its superior strength characters racing the traditional materials in strength to weight ratio. The developments of new materials are on the anvil and are growing day by day. In this work, two-body abrasive wear test with different loads and abrading distances were performed at room temperature by using a pin on a disk apparatus to...
