Fiber reinforced polymeric composites with tailorable electrical resistivities and process for preparing the same
The present invention relates to polymer composite materials, more particularly relates to composite materials with tailor made surface electrical resistivities in the range of 109 to 10−1 Ω/sq. and process of making the same. The process for preparing Fiber Reinforced Polymeric (FRP) Composite, said process comprising acts of homogeneously mixing 1-30% by weight of different electrically conducting fillers in matrix resin system to obtain resin mix; wetting dry preforms using the resin mix; compacting the wetted preforms to obtain green composite; curing the green composite; and post-curing the cured composite to prepare the FRP Composite.
