Abstract:

Interlayer fractures and fractures are a type of damage that is common in layer composite materials. Separation mode is the break-up mode where inter layers break the easiest and the lowest inter layers break-up density. This study examined the impact of environmental temperatures between 140°C and -160°C on the inter layer broken density and broken mechanics of carbon fiber/epoxy composite material. In the findings obtained, when the medium temperature fell below 0oC, the inter layer breakdown density decreased compared to the breakdown density at the medium temperature 23oC. But the breaking characteristics at low medium temperatures are similar to the breaking characteristics at 23oC. At high environmental temperatures, the cams transition temperature of the matrix material constitutes a natural limit for the development of fractures. The epoxy matrix cams has not progressed in temperatures close to the transition temperature. At temperatures above the transmission temperature, the breakdown behavior of the material has changed completely.
