摘要

"dry self-supporting fibrous material, slotted tape or tow, method for making a slotted tape or tow, preform for receiving resin-infused liquid matrix resin, and, binder composition". disclosed herein is a self-supporting dry fibrous material, the fibers of which have been treated with a binder composition. The fibrous material may be slotted into tapes or tow that are suitable for use in an automated tape deposition (atl) or automated fiber placement (afp) process. This fibrous material is suitable for forming preforms which are configured to receive a resin infusion matrix resin in the fabrication of structural composite parts.
