Device for manufacturing hollow mold part from fiber-reinforced composite in e.g. automotive engineering, has inner molding tool whose upper surface includes flow channel opened towards cavity and applied with reactive polymer matrix

摘要

The device has an outer molding tool (2) enclosing a hollow space, where an inner contour of the space corresponds to an outer contour of a hollow mold part. An inner molding tool (20) is arranged in the space and expanded by volume increase in a direction of the outer tool. The tools form a cavity that follows geometry of the mold part. The cavity accommodates a reinforcing textile (19), where a reactive polymer matrix (18) is injected into the cavity. An upper surface of the inner tool attached to the cavity includes a flow channel (22) opened towards the cavity and applied with the matrix. An independent claim is also included for a method for manufacturing a hollow mold part from a fiber-reinforced composite.
