Abstract
An automated method for producing a fibrous preform on a tool surface. Such fibrous preform is configured to receive liquid resin via resin infusion. A disposable layer containing a small amount of radiation absorbing material is placed onto the tool surface prior to the automated placement of the first ply of dry fibrous material. Particles of a polymeric or resinous binder are applied on an exposed surface of the disposable layer to enhance adhesion of the first ply. The dry fibrous material may be in the form of elongated, narrow-width fiber tapes or broader fabrics that can be deposited onto the tool surface by an automated placement method. The disposable layer may be in the form of a flexible polymeric film, a release film, a peel ply or a polymer-coated glass cloth.
