Polymer matrix composites(PMC) are the choicest among
the structural grade materials for advanced composite
applications, which require excellent mechanical properties. Though their unmatched specific strength/
stiffness and light weight characteristics are contributed
by the fiber phase, the crucial long term properties like,
high service temperature resistance, damage tolerance 0 and hot-wet property retention are provided by the polymer matrix phase. Thus a high performance composite is a combination of advanced reinforcements like carbon/Glass fibers, and polymer matrix with high glass transition temperature toughness and low moisture up take
