MECHANICAL CHARACTERIZATION AND COMPARISON OF GLASS FIBER AND FIBRE REINFORCEMENT WITH ALUMINIUM ALLOY (GFRAA) TO IMPROVE THE STRENGTHENING FOR AUTOMOTIVE APPLICATION

There is a wide spread involvement in the presently graded materials, because of which their major important properties such as resistance to corrosion, high hardness ability, resistance to oxidation and resistance to erosion, stability in thermal and chemical during cryogenic and increased operating temperatures. Such properties makes many application to rely on them for many applications, which including boundary thermal coating (TBC) on metallic and non metallic substrates used at peak temperatures. Thermal barrier coatings has been strongly applied to the internal combustion engine, in peculiar the combustion antechamber for the purpose to simulate adiabatic process. The primary motive is not only for supressing the interior cylinder heat ejection and thermal load fatigue protection of benaeth metallic surfaces, but also for possible reduction of engine waste émissions and consumptiion of brake specific fuel. The relying usage of TBC dimnishes the loss of heat from engine cooling jacket through the channel of surface opened to the heat conduction such as the head of the cylinder, liner, piston ring and piston crown. The protection and performance of the combustion region within the ceramic coating may also affects the combustion activity and, hence, the behaviour of exhaust emissions and performance of the of engine improve. On the other side, the need of supressing the consumption of fuel rate and inflation the engine thermal effectiveness of lead to the adoption of higher compression ratios, in specific for diesel engines, and deflated in cylinder heat ejection.
