This paper describes a study of application LCA (Life Cycle Analysis/Assessment) concept on polymer based composite materials. Composite materials are considered that they are not environmental conscious materials because of their difficulty in recycling. However, they can be used for a long time compared with conventional materials. In addition, they can bring high fuel efficiency by reducing weight of products. Therefore, environmental load of materials should be evaluated all through lifetime period and applying LCA to composite materials is important to develop environmental conscious composites. In this paper, first, application LCA to CFRP is mentioned. And to evaluate environmental load per unit performance, the calculation system for selecting materials according to mechanical properties using WWW is introduced. Finally, sensitivity analysis examples for polymer data are presented and difference of importance among inventory data is discussed.
