ComPRIS or the Composites Pressure Resins Infusion System is a new technology for the production of composite materials. The ComPRIS process is particularly appropriate for the lamination of dissimilar materials and the reinforcement of materials with FRP.

To view the animation of the two basic ComPRIS processes, please click the images below (PC only, click ONCE in the new window to start the show). An online slide show is available for PC users, the original Powerpoint slide show (~ 1 MB) is available for both PC and Mac users.

Variant 1. The pressure gradient ComPRIS process: When employing a bagging system similar to VARTM processes, air is pushed out of the fabric by the flow of the resin,and is voided to a trap.

Variant 2. The BPM ComPRIS process: A bladder of buffer material (BPM) that allows air to be compressed in one or more interior cavities is also be used in non-bagged systems to void air from a part being infused with resin.

Society 2004 Annual Meeting and Technical Conference, Cornell University, Ithaca, NY, Oct. 11-13, 2004.

At present we do not produce composites commercially, rather we develop prototype products at our University of Maine state of the art facilities to attract industrial partners for development of the technology. We welcome your thoughts and opportunities to collaborate on the development of products that can be better produced using our ComPRIS technology.
