Summary: | 碩士 === 國立屏東科技大學 === 木材科學與設計系所 === 102 === This study uses the set temperature electric heat gun bent Moso bamboo with set different temperatures and the heating time, and discriminate upper, middle and lower from bamboo split to explore and bamboo bending skills in product design and production, the results of this study shows:
1. The use a electric heat gun to bend bamboo, temperature setting 650 ℃, time of 2 min are up close to the curved portion of the glass transition temperature of bamboo, there will be a smaller bending rebound.
2. Bending method is use to bamboo skin outside (raised face) which is the most suitable for bamboo bending, electric heat gun temperature setting to 650 ℃, heating time to 2 min to bend, to reach 9.21% of the small springback rate.
3. Minimum bend radius destructive testing showed, in the 3 mm bamboo strip that the upper and middle is succeed of the bamboo bending ,but in the lower bend is cracking. Relationship site with bamboo minimum bend radius is unapparent, although bamboo bending spring back rate is vary from different parts, but the minimum bend radius is not direct and correlation.
4. Bamboo chair use bamboo as material to design, in addition to the use of bamboo pliable outer characteristics of bamboo itself will also be reflected in the bending resistance and stiffness of a bamboo chair.The bamboo chair designed as an isosceles triangle with two ladder-type, ladder provides flexible comfort and isosceles triangle with bamboo bending stiffness to make bamboo chair.
