Sliding Wear Behaviour of Walnut Shell Powder Filled Vinyl Ester/ WSP Green Composites

sliding wear behaviour of walnut shell powder filled vinyl ester/ wsp green composites

polyvinyl ester green composites were synthesized with walnut shell powder (wsp) by in-situ polymerization technique. the green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...

Metal Powder-filled Polyethylene Composites. v. Thermal Properties Metal Powder-filled Polyethylene Composites. v. Thermal Properties

Thermal properties—such as thermal conductivity, thermal diffusivity, and specific heat—of metal (copper, zinc, iron, and bronze) powder-filled high-density polyethylene composites are investigated experimentally in the range of filler content 0–24% by volume. Experimental results show a region of low particle content, 0–16% by volume, where the particles are distributed homogeneously in the po...

Experimental Study on Wear Behaviour of Sic Filled Hybrid Composites Using Taguchi Method

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...

DRY SLIDING WEAR BEHAVIOUR OF STIR CAST LM 25/ZrO2 METAL MATRIX COMPOSITES

In the present study, an investigation into wear properties has been carried out to identify the influence of ZrO2 as the reinforcement material on the LM25 MMC composite. Aluminum LM25 is selected as the base material, and it is reinforced with varying proportions of 0, 3, 6, 9, 12 and 15% of zirconia (ZrO2) manufactured by stir casting. Six tensile test and wear test samples were prepared acc...

Effect of Micro Glass Flake on Morphological and Rheological Behaviour of Epoxy Vinyl Ester Composite Coatings

In the present work, attempts were made to investigate the reinforcement and treatment effect of GF on morphological and rheological behaviour of GF/epoxy vinyl ester composites. GF was incorporated into epoxy vinyl ester resin by sonication, and mechanical agitation. Rheological and morphological properties were studied as a function of particle treatment and size distributions. The dispersion...
