ABSTRACT:
A delamination development preventable structure is provided to prevent the development of delamination in a sandwich panel including a core and surface plates attached to the opposite surfaces of the core with respect to the thickness of the core.Arresters5are protruded inward with respect to directions parallel to the thickness of a core3from surface plates4aand4b. The development of a delaminated part formed by the separation of a part of the surface plate4afrom the core3and that of a delaminated part formed by the separation of a part of the surface plate4bfrom the core3beyond the arresters5can be prevented. Thus delamination can be limited to a narrow local region and the spread of the delaminated part over the entire sandwich panel2can be prevented. Thus the development of delamination in the sandwich panel2can be prevented and the durability of the sandwich panel2can be enhanced.
