碩士 === 國立臺灣大學 === 森林環境暨資源學研究所 === 105 === The purpose of this study was to investigate the panel products used in the system cabinets and furniture industry, including wood core panel, particle board and oriented strand board designed specifically for the use of furniture. First, corner joints constructed with removable metal KD connectors were compared with the traditional connections in order to understand the bending strength difference. Results will improve the strength of furniture joints and increase the safety and life time of products. The experimental results show that particle board constructed with wood screws (S),dowel (D) and dowel with Minifix® Häfele (DM) in the compression and extension have maximum bending moment resistance than the other two panels do. Since there are many similar KD connectors in the market, two types of products, Taiwanese imitation and the German Häfele original goods, were used to compare the strength differences each other. For the corner joint strength of panel furniture, oriented strand board (OSB) constructed with KD connectors has maximum bending moment resistance. The average compression and tension bending moment of OSB L-type corner joints with Häfele Minifix® were 15,136 and 22,459 N-mm, respectively. And the average compression and tension bending moment of OSB L-type corner joints with domestic Minifix were 14,532 and 22,927 N-mm, respectively. However, there was no significant differences between Häfele Minifix® and domestic one according to Tukey test results. Furthermore, the average compression and tension bending moment of OSB L-type corner joints with Häfele Rafix were 8,076 and 14,822 N-mm, respectively. And, the average compression and tension bending moment of OSB L-type corner joints with domestic Rafix were 12,284 and 18,202 N-mm, respectively. According to Tukey test results, there was significant differences between Häfele Minifix® and domestic one. This study can provide as scientific basis for the furniture design to the researcher, so as to facilitate the furniture engineering design and development of the furniture structure.
