초록 ▼

A unitary vacuum bag for forming of a fiber reinforced composite article, made of a fabric mesh reinforced curable elastomer, having a smooth surface on both sides. The bag is constructed upon the surface of the article which is to be reproduced and upon a planar flange extension of the mold for said article. A rigid vacuum chamber assembly consisting of a planar fiber reinforced composite or equivalent sheet is sealed on the outer periphery to the mold flange extension and on the inner periphery to the top surface of the bag by rubber seals which are attached to the vacuum chamber assembly under surface. A vacuum port through the vacuum chamber assembly between the rubber seals allows vacuum to be applied to the chamber causing it to be pressed by atmospheric pressure to the mold flange extension and bag periphery thus sealing the bag to the mold periphery and simultaneously providing a continuous vacuum source around the entire periphery of the bag. The vacuum is connected to the fiber reinforcement in the mold via multiple self sealing micro porous conduits passing under the bag periphery between the vacuum chamber and the mold cavity containing the fiber reinforcement for the article. The bag is constructed within integral multiple injection ports positioned at strategic locations for introduction of catalysed thermoset resins into the reinforcement. Optionally, a series of tubular air pressure channels are made integral to the bag which, when inflated, cause the bag to distort, resulting in resin flow channels forming under the bag on both sides of the inflated air channel. Deflation of the air channel returns the bag to it\s original contour with no trace of the flow channel evident on the surface of the completed article.

대표청구항 ▼

An apparatus for manufacturing a fiber reinforced polymer article comprising of: a contact mold with a periphery and an inner surface defining the shape of the outer surface of the article to be molded, a peripheral integral mold flange on the contact mold periphery such that the mold periphery is extended in a continuous relatively planar configuration, an impervious flexible silicone bag mold defining the shape of the inner surface of the article to be molded and containing means for introducing liquid polymer through the bag into the dry reinforcement of the article to be molded, a clamping assembly to provide a means of sealing the silicone bag peripherally to the mold flange having a rigid planar shell with inner and outer seals which contact the contact mold flange to create a vacuum chamber around the periphery of the article to be molded, a self sealing microporous conduit in fluid communication with the peripheral vacuum chamber and the reinforcement of the article to be molded for the purpose of evacuating the mold cavity defined by the contact mold surface and the silicone bag inner surface.
