Experimental investigation on Heat Distortion Temperature parameter of Polymer Matrix Composites for solar Panel Applications
摘要： In this paper the examination intended to create polymer matrix composites with polyester and vinyl ester better warmth opposition. The glass fiber with polyester favoured with various piece of composite with expansion of various fillers in various weight parts was created. Created utilizing vacuum sack shaping procedure. The mechanical properties were assessed utilizing Universal testing machine and the warmth mutilation temperature is the temperature at which a polymer or plastic example disfigures under a predetermined load. This property of a given plastic material is connected in numerous parts of mechanical assembly with various loads. Better mechanical properties and wear properties were gotten with increment in weight level of auxiliary fortification substance. The Heat Distortion Temperature is controlled by the test strategy delineated in ASTM D648.Further it was discovered that The extent 40:60 and 20:80 does not framed as flawless IPN consequently it is discovered that 80% vinyl ester and 20%poyurethane have great flexibility and sturdiness in correlation with different proportions.

Effect of interfacial voltage on tribological characteristics of polysilicon micro-contacts tested in ambient air under dynamic impact conditions
摘要： A polycrystalline silicon microtribometer was used to examine the evolution of tribological properties under dynamic mechanical impact and hot switching conditions. Changes in surface properties were tracked via periodic static adhesion tests. Surfaces experienced two distinct periods in the course of the dynamic lifetime – a run-in phase with little measurable surface modification and a degradation phase with significant surface modification and corresponding increases in the measured adhesion force. No statistically significant differences were found in either the run-in period length or the degradation rate between hot switching conditions and purely mechanical switching, microelectromechanical systems.
