Thermal Stability of Compatibilised Natural Rubber/ Chitosan Blends
Abstract: The thermal degradation behavior of Natural Rubber /Chitosan (NR/CS) blends compatibilised with maleic anhydride (MA) was studied by thermogravimetric analysis (TGA). The TGA shows that the MA modified blends are more stable than the pure blends. MA acts as a reactive compatibiliser in NR/CS blends. MA grafted NR chain is highly reactive towards the functional group on the chitosan moiety, and when pressing at elevated temperature interaction develops between the …

Development of Aluminium Based Silicon Carbide Particulate Metal Matrix Composite for Cylinder Liner
Abstract: Cylinder liner is used in engine block to give a wear protective surface for piston and piston rings. Friction accounts for a loss of over 30% of the total vehicle power. Over half of that power loss can be attributed to the frictional loss between piston rings and cylinder bores. The best approach for improving power train efficiency is to reduce friction loss and the way for reducing the rolling …
