A Study on Craze Occurrence by Change of the Environment in Polycarbonate

摘要

In the polycarbonate as for which the polymer material used substituting metal is increasing every year and which is classified into engineering plastic especially in. Book research, which craze generates since it is low crystal object structure in. Which is used for optical parts, auto parts, etc. and is capturing the spotlight, however this material, it sets to craze at the tip of a crack. It investigated what influence craze and crack progresses, which are generated by environmental change, would have by the optical elastic method and the course textile method.
