The dynamic characterization of polymer composites is becoming an increasingly important USN topic. As the Navy moves towards increased construction of composite high-speed craft, it becomes very important to have a complete understanding of their strength, stiffness and durability in such environments. This requires a proper composite materials database. The parameters necessary to deduce methods for the required tests have yet to be determined. Once they are, the test methods and equipment needed to produce the database could be designed. Impact Matrix Systems, LLC has a large database defining the response of a broad range of composite materials to the high strain rate impact events typically encountered by high-speed craft. Its source is a seven-year test program executed in conjunction with a major US producer of high-speed craft. The information includes high rate strain and accelerometer data. IMS has outlined a comprehensive Phase I project for the development of the required strain event definitions and test methodology. IMS will employ its combined internal and affiliate expertise to deliver an effective combined solution. Successful proposal execution proposal will provide benefits to the USN in the form of lighter weight, lower cost and more predictably durable composite craft structures.
Benefit: Expected benefits of this program will be a better understanding and ability to predict the durability and true safety factors of the vessels produced drawing upon this information. This will result in potential cost reductions for craft produced with composite materials. In addition, they should also possess longer life expectancies and lower maintenance/repair cost requirements. The generation of improved
