Pre-formed roving

In the preform process, the roving is short-cut and sprayed on a web of a predetermined shape, while spraying a small amount of resin to fix the fiber web, and then moving the formed fiber web into the metal mold, and injecting the resin into hot press forming, That is the product. The performance requirements for the roving for this process are essentially the same as for the roving without jetting.
