Recently in the automobile industries, the development of environment friendly materials for improving the safety and
fuel efficiency of automobiles has come to the fore. As the demand for the technological development to achieve high
performance and high efficiency increases, the research on applying advanced high-strength steel to parts manufactured by the
hot press process has progressed. Further, research and development for fuel efficiency through additional weight reduction
using Tailor Welded Blanks (TWBs) and Partial Quenching (PQ) has quickly spread in the automobile industry. Moreover,
lighter materials than those currently used, materials having a high strength-weight-ratio and specific strength, are required
such as hybrid steel/CFRP composites. Many car components have been replaced with various materials to improve collision
toughness and safety during car crash. However, the standard of evaluation to replace auto part is still lacking. The standard
needs to depend on mechanical properties of tensile and bending. The car crash test was conducted at IIHS to evaluate safety.
But it’s expensive and hard to evaluate collision toughness each car component. In this study, the side crash test was conducted
by simulation and the collision characteristic of the center-pillar was evaluated. Fracture toughness was compared according
to materials to propose a standard of collision test condition. As a result, the correlation between mechanical properties, weigh
reduction and collision toughness was investigated.
