금속, 유리섬유 및 탄소섬유로 보강된 코르크 보드를 복합한 온대산재 및남양재 원목마루판의 치수안정성

초록

In this study, the dimensional stability of cork composite wood floorings were evaluated using temperate and tropical hardwoods as the face layer and cork composite boards reinforced with metal, glass fiber, and carbon fiber as the core layer. Regarding the average water absorption rate of cork composite wood floorings according to the face layer, Ginkgo biloba L.(Ma) showed the highest value(35.6%), while Bangkirai(Ba) showed the lowest value(18.4%). Additionally, it was confirmed that tropical hardwoods, which have a relatively higher density compared to temperate hardwoods, showed a lower water absorption rate. Regarding the average thickness swelling according to the face layer, Zelkova serrata(Ze) showed the highest value(5.3%), while Bangkirai(Ba) showed the lowest value(3.4%). In addition, the average water absorption rate of the cork composite wood floorings was higher than that of commercial laminate flooring(2.2%), and was similar to or slightly lower than that of commercial wood flooring(30.2%) and engineered wood flooring(33.5%). Furthermore, regarding the average thickness swelling, the cork composite wood floorings were higher than that of commercial laminate flooring(0.8%) and engineered wood flooring(1.8%), and lower than that of commercial wood flooring(6.7%). Through these results, it was confirmed that the cork composite wood floorings reinforced with dissimilar materials have dimensional stability that meets KS standards, and it was determined that it can be effectively utilized as a flooring material for construction.
