Prediction of residual stresses and distortion in carbon fiber-epoxy composite parts due to curing process using finite element analysis

Tavakol, Behrouz; Roozbehjavan, Pooneh; Ahmed, Ashraf Uddin; Das, Rony; Joven, Ronald; Koushyar, Hoda; Rodriguez, Alejandro J.; Minaie, Bob (Wiley-Blackwell, 2013-04-15)

To predict the final geometry of carbon fiber-epoxy composite parts, a methodology is introduced that takes into account cure kinetics, cure shrinkage, thermal strains, tool-part interface, and development of mechanical ...
Stress relaxation behavior of carbon fiber-epoxy prepreg composites during and after cure

Das, Rony (Wichita State University, 2012-05)

This study presents the experimental results of time-temperature dependent viscoelastic behavior and cure kinetics of two commercial carbon fiber/epoxy prepregs, IM7/977-2 unidirectional tape (UD) and IM7/977-2 plain weave ...
