Description:FIELD OF INVENTION
[0001] Embodiments of the present disclosure relate to the field of nanotechnology, and more particularly to a composition of graphene reinforced carbon fiber and a method thereof.
BACKGROUND
[0002] There exist a plurality of ways to fabricate composite components. Fabrication of the composite components involves moulding to shape a resin and reinforcement. A mould tool is required to shape the resin and the reinforcement before curing. One way of fabricating the composite components includes hand layup method. The hand layup method includes placing one or more prepreg layers by hand onto the moulding tool to obtain a laminated stack. The resin is later infused on the laminated stack. The laminated stack may be debulked once the resin is infused.
[0003] Although debulking may be done by hand with rollers, majority of fabricators prefer a vacuum-bagging technique which involves placing plastic sheet materials over the laminated stack, sealing edges of the laminated stack, adding one or more ports for air hoses, and then evacuating air between the sheet and the laminated stack using a vacuum pump. Debulking not only consolidates the laminated stack but also removes air trapped in the laminated stack, which may create air pockets in the laminated stack, weakening the composite components. The laminated stack which is debulked may be allowed to cure in a number of ways. At present, the resin involved in the fabrication of the composite components is based on petro chemicals. The resin is toxic and recyclability of the same is difficult, thereby affecting sustainability of environment.
[0004] Hence, there is a need for an improved composition of graphene reinforced carbon fiber and a method thereof to address the aforementioned issue(s).
