Design and Validation of Standardized Wave Slam Test Equipment and Time-Temperature Superposition Procedures

Wave slam loading on hull structures are characterized by a rapid rise to a very high peak pressure, followed by a slower drop to a longer duration, lower pressure. An event can be as short as 10 msec, with a 200 psi peak pressure. Loads of this type are known to be a major consideration in the design of composite high speed hulls, but to date no efficient method for testing panels in a laboratory with a properly simulated loading has been developed. KaZaK Composites proposes the design, development and demonstration of a novel test method capable of rapidly loading multiple composite panels with an accurate simulation of wave slam pressure-time pulse. KaZaK’s system will feature multiple panels loaded at the same time, as well as provisions to incorporate accelerated aging technology to further reduce test time. We will work with a commercial boat builder with industry-leading slam test experience, as well as a world–renowned composite test expert to ensure that our evolving test process far exceeds current state of the art. Our Phase I program will conclude with hardware demonstration of the test procedure concept. The ultimate objective will be ASTM certification of the proposed methodology.
