| dc.description.abstract | The composite materials are widely using in place of conventional materials due to its particular properties. There are a number of methods to manufacture composite material products but Vacuum Assisted Resin Transfer Molding (VARTM) technology has many advantages over RTM. It is a cost effective molding method especially using for long sheets. Our aim is to make an understanding and feasibility of this technology. Our aim is to manufacture a composite material sheet by using VARTM technology. And after that to make an understanding of VARTM for complex geometry. This is not an easy task because finishing of sheet is not easy to achieve without upper part of mold. Flow of resin effects the finishing of the part. If flow is inappropriate then voids can be produce. Flow timing is an important factor when it will slow or fast it results a defective part. Incomplete impregnation of resin will cause dry spots in the manufactured part. Distribution media places on the top of the fiber to accelerate the resin flow. So, porosity, permeability and thickness of distribution media and fiber or reinforcement are also important factors. Another challenge is to design VARTM process. Inlets for resin impregnation is an important factor that how many inlets should be for proper impregnation and where these inlets should be introduced to the mold. Leakage of vacuum bag is another challenge so proper sealing of system is required. Vacuum timing is also notable factor. Pressure and temperature of resin to introduce into the mold is also part of design challenges which we will achieve. Finishing of the final part including less voids, better surface finishing, precise and dimensions is the main aim of our project which we will achieve. | en_US |
