<p>Polymer composite though high strength promising material, its wear damage is a real matter of concern. Thus to improve its wear performance the polymers and composites are treated cryogenically. Optimization of cryo-treatment for fiber and particulate reinforced PBT composite was done by evaluation of cryo-treated samples for structural, mechanical and thermal properties. In addition to this, as the interface has decisive role in case of composite which governs the properties of composite, the interface of the composites was also investigated and the change at the interface were monitored and evaluated through theoretical predictions as well. This invention concludes that the optimized cryo-treatment is effective for the polymer composites to improve its wear performance. Following invention is described in detail with the help of Figure.3 of sheet 2 shows Young's modulus value of (i) Glass fibers reinforced PBT composites (ii) Wollastonite reinforced PBT composites for untreated and cryo-treated at (-80°C, -140°C and -185°C) for the samples exhibiting highest modulus at the mentioned temperature.</p> |
