Carbon fibre reinforced polymer (CFRP) composites have been extensively used because of their excellent performance and lightweight. Due to its widespread use, manufacturing scrap and end-of-life prepregs is constantly generated. Investigation into the potential of CFRP reclamation by second impregnation process via hand lay-up was performed. Focusing on the effects of number of layers (2, 4, 6 and 8 layers), to the physical and mechanical properties of laminated secondary impregnated Carbon Fibre Prepreg Epoxy (i-CFPE) composites. It was then compared with laminated Carbon Fibre Prepreg composites without second impregnation (w-CFP). Samples were tested under tension, flexural and impact. Mechanical properties of i-CFPE increased with the increase of laminates layer in the composites. Furthermore, i-CFPE laminated composites showed better performances if compared to the w-CFP.
