Title:
PRODUCTION OF FIBER REINFORCED MOLDED PRODUCT
Document Type and Number:
Japanese Patent JP3146120
Kind Code:
B2
Abstract:
PURPOSE: To prevent the generation of voids in a molded product by injecting a liquid resin into a reinforcing fiber material so that the permeability of the reinforcing fiber material with the liquid resin in its surface direction becomes larger than that in its thickness direction before performing mold clamping and compression molding.
CONSTITUTION: A reinforcing fiber material 40 is arranged to the wall surface 22 of a lower mold 20. At this time, a mold surface 12 is in contact with the reinforcing fiber material 40. Subsequently, a liquid resin 60 is supplied to a resin supply passage 16 to be allowed to fall from the resin supply passage 16 opened to the rear surface of an upper mold 20 to be injected into the lower mold 20. Next, the upper mold 10 is allowed to fall to be clamped to the lower mold 20. The mold surface 12 of the upper mold 10 and the mold surface 22 of the lower mold 20 come into contact with each other and the mold register surfaces 14, 24 of both molds come into contact with each other through a packing 30. Herein, a mold clamping speed is adjusted so that the permeability of the reinforcing material 40 with the liquid resin 60 in its surface direction becomes larger than that in its thickness direction and the reinforcing fiber material 40 containing the liquid resin is compressed at this mold clamping speed to be heated under pressure.
