Dynamic Parameters for High Speed Craft Composite Component Testing

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.
