| 摘要 |
Polymer composite products, including products made of polymer concrete, reinforced polymer concrete and reinforced plastics, such as bulk molding compound, sheet molding compound, mineral molding compound and advanced molding compound systems, are produced by the simultaneous application of vibration, heat and pressure to a mixture of filler and polymeric binder. The simultaneous application of vibration, heat and pressure provides a protective layer of polymerized binder that protects the surfaces of the mold and provides products that are substantially free of curling, cracking or voids. The process of the present invention substantially reduces the time required to cure polymer composite products. |
