METHOD AND APPARATUS FOR IMPREGNATING SEMI-FINISHED FIBROUS PRODUCTS

摘要

In a method for impregnating semi-finished fibrous products using resin as the impregnating means, winding or laying the semi-finished fibrous products in a plurality of layers on top of one another onto a receiving carrier is initially performed. Here, lower layers lie close to the receiving carrier, and upper layers lie more remote therefrom. The receiving carrier is configured so as to be permeable to the impregnating means. The impregnating means is then introduced through the receiving carrier into the semi-finished fibrous products, wherein the impregnating means initially permeates the lower layers and then permeates the upper layers of the semi-finished fibrous products.

1. A method for impregnating semi-finished fibrous products in the form of long or endless fibers or fiber bundles using an impregnating means, preferably a liquid impregnating means and/or resin, the method comprising the following steps:
winding or laying the semi-finished fibrous products onto a receiving carrier which is permeable to the impregnating means, wherein the semi-finished fibrous products are provided in a plurality of layers on top of and across one another, wherein lower layers lie so as to be close to the receiving carrier and upper layers lie so as to be more remote from the receiving carrier, introducing the impregnating means into the semi-finished fibrous products, wherein the impregnating means hereby passes through the receiving carrier at least once.
