Abstract

The present invention proposes a method of industrial composite manufacturing. The method combines the resin transferring molding method with vacuum process and compression process in appropriate orders for achieving high quality products. In the curing process, microwaves are used to harden the plastic resin in the mold. Specifically, the main steps of the method are following: step 1: preparation of materials and equipment; Step 2: Disposition of the reinforced fibers/fabrics and mold closing at the extend position; Step 3: Vacuum and transfer plastic resin into the mold; Step 4: Mold closing by compression pressure; Step 5: Plastic resin curing by using a microwave system; Step 6: Open the mold and take the composite product.
