Abstract
Hybrid composite strut tower was designed to prevent permanent deformation of upper mount by the impact from the uneven road. When exceeding energy absorption capacity of tire and suspension systems, residual impact is delivered to upper mount. Especially, in case of using high-rigidity suspension system for high driving performance, the conventional strut tower can be easily deformed due to reduction of energy absorption capacity of suspension systems. In this study, optimal design of hybrid composite strut tower which made of back-up metal and carbon fiber reinforced composite was suggested by using finite element analysis, and low velocity impact test was performed to investigate their dynamic characteristics. Also, 3D measuring and ultra c-scanning methods were carried out to diagnose damages in the strut towers.
