Abstract

The purpose of this study is to applied reinforcement method at the joint part of the sandwich panel. Becasue the joint part of the sandwich panel has a disadvantage that flame spreads fast inside steel plates in the event of fire, leading to a big fire rapidly. In this study, the combustion performance was measured through KS F ISO 13784-1 "Reaction-to-fire tests for sandwich panel building systems" according to the application of reinforcement method to prevent flame from being brought into the internal joint of the sandwich panel. For the reinforcement inside the panel, the tape produced using expanded graphite-based heat-expandable glass fiber was attached. As a result, it was confirmed that the prevention of flame from being brought into the internal joint could delay the flash over time and the collapse of the test specimen.
