Abstract

In this paper, we propose a method to prevent wrinkling o.f the facings of a sandwich panel structure, whose outer and inner facings are at different temperatures. So, by using this method the wrinkling of the outer facing of a sandwich panel structure such as a sandwich panel refrigerator box can be prevented. In order to prevent wrinkling of the facings of the structure, it is necessary to determine the wrinkling stress by using a compression test, and to reduce the thermal stress under the wrinkling stress for a sandwich panel structure. And it is observed that a sandwich panel structure with a slit in the facing reduces the thermal stress. In this study, we use sandwich panel refrigerator containers to examine whether the prevent method can prevent wrinkling.
