Experimental investigation of carbon fibre reinforced composites infused with Resin X manufactured using different processes

Currently, in the processing of composite materials using resins, it is more common to use thermosetting resins as the matrix to form composite products because thermosetting resins require lower processing temperature and are less viscous. This causes the resin to easily impregnate into the reinfor...
