Preliminary Study on Bamboo Timber of Ximeng, Yunnan
The physical and mechanical properties of 1-5-years-old dragon bamboo and the physical and mechanical properties of different parts of dragon bamboo were studied. The results showed that the selection of bamboo age was an important factor affecting the performance of bamboo products, and the selection of different parts of bamboo should also be considered. The results showed that the bamboo wall thickness is uneven, resulting in greater shrinkage stress and easier cracking, and the bamboo tube at the root was easier to crack. The bamboo tube at the root of Phyllostachys praecox is easier to crack due to its higher moisture content. Longzhu, whose bamboo age is less than 4 years, is more prone to cracking. Bamboo wall thickness is one of the important factors affecting bamboo cracking, and bamboo with thinner bamboo wall is more prone to cracking.
