CO-INJECTION RESIN TRANSFER MOLDING (CIRTM) TECHNIQUE The U.S. Army Research Laboratory and The University of Delaware Center for Composite Materials announce the joint development a novel composite manufacturing technique that enables the injection of multiple resin systems into a single fiber layup and mold/vacuum bag. The Co-Injection Resin Transfer Molding (CIRTM) technique was developed to meet the need for affordable manufacturing of integral armor for Army applications. This composite consists of multiple layers that contribute various unique properties (fire resistance, strength, ballistic protection, ect.) to the final composite. CIRTM offers the potential to satisfy multifunctional requirements, reduce costs, and increase quality, performance and durability. The cost and time reduction aspects of CIRTM will become particularly apparent during the manufacture of composites employing multiple resin systems. Additionally, CIRTM eliminates the need for secondary bonding operations and reduces the potential for disbonds. A patent application has beensubmitted to the U.S. Patent and Trademark Office. A licensing meeting is scheduled for Thursday, 29 January 1998, at Aberdeen Proving Ground, MD. Contact Mike Rausa at 410-278-5028 or visit http://www.fedlabs.org/ma/pl for technical and registration information. A non-disclosure agreement MUST be signed before attending the licensing meeting.
