Fatigue Assessment of Hybrid Composite Joint for the Tilting Car Body

틸팅차량용 Hybrid차체 접합체결부의 피로 특성 평가

Fatigue fracture behavior of a hybrid joint between side-panel and under-frame by riveting and adhesive bonding has been evaluated. Two kinds of joint specimens based on real geometry were fabricated for shearing test as well as bending test. Static and cyclic loadings were used for fatigue assessment. Fatigue fracture results obtained by such experiments were reflected in modifications of design parameters of the hybrid joint.
