- Abstract
- This final report describes the results of a six month study by Coleman Research Corporation (CRC) to investigate the impact of storage environments on composite materials. The objectives developed to achieve this program consisted of the following tasks: 1) Locate and identify the use of composite materials designed into military weapons; 2) Perform a literature search to determine if studies were performed by various military agencies; 3) Design a data base which will store the physical characteristics of composite materials; 4) Design a test program which will demonstrate the effects of storage environments on composite materials; 5) Prepare a request for bid to the local test laboratories to perform these tests; 6) Prepare Phase 2 proposal; and 7) Prepare final report. CRC's surveys of government, industry, and other literature sources yielded the conclusion that composite materials are limited in use in the design of fielded weapon systems and long term environmental effects on composite materials to lower the costs, weight, and maintenance requirements. In summary, while composite materials have a bright future, they are currently limited in deployed weapons systems.
