Abstract
Official abstract text for this publication.
A method for producing FRP in which a preform made of a reinforcing fiber base material is disposed in a cavity of a mold, a resin injection path and a suction path that sucks at least air are provided to the mold, and resin from the resin injection path is caused to flow in the direction toward the suction path in the cavity to be impregnated into the preform, wherein a high flow resistance region for partially making the resin flowing in the preform hardly flow is formed in the preform itself, and a flow front of the resin flowing in the direction toward the suction path through the high flow resistance region is controlled to settle within a permitted region that has been predetermined relative to a shape of a product to be molded.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing FRP comprising disposing a preform made of a reinforcing fiber base material in a cavity of a mold, providing a resin injection path and a suction path that sucks at least air to said mold, and causing resin from said resin injection path to flow in a direction toward said suction path in said cavity to be impregnated into said preform, wherein 1) a high flow resistance region that partially causes said resin flowing in said prefor…
