Kordsa tests process-induced residual stresses in manufacturing thermosetting polymers

Fiber reinforced composite materials have been increasingly used in various structural components in the aerospace and automotive industries. This increased usage requires a detailed understanding of the process-induced residual stresses. Residual stresses are the stresses that remain in a material or structure after the source of these stresses has been removed. The non-uniform distribution of residual stresses results in deformation, matrix cracking, and even delamination.

The article in the Reinforcer Magazine by the Project Leader Dr. Fatih Ertugrul Öz, presents process-induced residual stresses and their distorting effects in the manufacture of thermosetting polymer composites and shows the effect of the different properties of constituents.
