Several efforts were made over the years to control vibration of structural components made of composite materials. This paper consists of study on effect of using shape memory alloy (SMA) to increase the damping of glass fiber reinforced plastic (GFRP) composites. A comparative study between SMA and steel was made as reinforcement material in GFRP composites to enhance damping. Dimensions of e...

Application of polyhydroxybutyrate (PHB) to plastic industry has expanded over the last decades due to its attracting features over petro-based plastic, and therefore, its waste accumulation in nature is inevitable. In the present study, a total of four bacterial strains, viz., MK3, PN12, PW1, and Lna3, were formulated into a consortium and subsequently used as biological tool for degradation o...

Now-a-days everyone is aware of the disadvantage Plastic and its various products. Around 300-400 tonnes plastic waste generated every year. This also results in man environmental pollution as well human health issues. But, this doesn’t mean that we completely don’t need plastic. It has much application field composites which trending a good alternative wood. Composite materials have significan...

The present paper investigates the effect of adding silica nanoparticles to an anhydride-cured epoxy polymer in bulk and when used as the matrix of carbonand glass-fibre reinforced composites. The formation of ‘hybrid’ epoxy polymers, containing both silica nanoparticles and carboxyl-terminated butadiene-acrylonitrile (CTBN) rubber microparticles, is also discussed. The structure/property relat...

Effects of accelerated and natural weathering on the molecular weight distribution (MWD) and crystallinity of polypropylene (PP) in wood plastic composites (WPC) were investigated. The composites were produced from pine fibers (60%) and PP (40%). Prolonged weathering caused an increase in wood degradation and erosion thereby leaving cracks and ‘‘pits’’ on the surface. Pyrolysis gas chromatograp...

The current research determines the most recent developments in natural fibres reinforced polylactic acid composites. Polylactic (PLA) is derived from renewable resources and capable of degrading microorganisms, eliminating pollution caused by petrochemical-based plastic. PLA promising biodegradable material among polymers since it easily attacked bacteria decomposes easily, releasing H2O, CO2,...
