Much research has been conducted to understand the damage tolerance behavior of polymer matrix composites, but there are so many parameters involved that the development of a generic model is rather difficult. The present paper proposes an information system, which can overcome such difficulty. In this system, a list of possible parameters is generated and used as input. The output contains compression strength after impact, dent depth and damage area as well as pertinent reference information. The information system is constituted in a relational database environment and tools from expert system technology are incorporated. Case examples are included to demonstrate the practical use of the software for both data retrieval and similarity studies.
