A METHOD OF PRODUCING LAMINATES OF REINFORCED OR NON-REINFORCED THERMOSETTIANG RESIN IN A LOW PRESSURE CHAMBER

摘要

The manufacturing method of glass fiber reinforced unsaturated polyester products spraying fibers andresin was des cribed. The resin is sprayed to the molds, which are placed in the isolated room which is partially vacuumed. The dense air surface layer is formed to above lamina to prevent the permeation of air. Then, the molds, lammina and surface layer are exposed to the atmosphere to remove the pores formed in the process.
