3001 竹繊維の引張強度特性(S40-1 天然繊維,グリーンコンポジットの機械的性質,S40 バイオマス由来材料の成形加工と特性評価)
詳細
Deformation and tensile response of Bamboo fibers for various Bamboo, Phyllostachys heterocycla, Phyllostachys bambusoides, Phyllostachys nigra and Phyllostachys Makinoi Hayata are investigated using Instron type tensile testing machine at room temperature. Fiber strength value to the direction of thickness for Bamboo increases with shifting outside location. Specific tensile strength of the Phyllostachys heterocycla is comparable to that of the commercial glass fiber. Additional Alkali treatment is effective to improve the fiber strength and the elastic modulus. However, the microcrak of the alkali-treated fiber along load axis, such as delamination craking is mainly observed at the lower strain range.
