Composite material has attracted attention of researchers due to light weight and good mechanical strength. Composition of the matrix and reinforcement will affect the strength of the composite material, as reinforcement i.e. fiber contribute to the good mechanical properties as compare to the matrix i.e. resin. It is necessary to study the manufacturing process which will give good fiber weight fraction, comparing the process Vacuum assisted resin transfer molding (VARTM) as proved to be having good fiber weight fraction. Here we have compared the VARTM, & Hand Moulding with three different material systems and found the enhanced tensile and flexural strength of two phase composite by VARTM process due to high fiber weight fraction .Results of these composite processes are compared with results of nanocomposites of nylon. Nanocomposites having better mechanical properties than composites.
