Abstract

Abstract: The experiment on the crude fiber content and mechanical characteristic of fresh tea leaf showed the elastic modulus of Tie-Guan-Yin、MaoXie、HuangDang、Fudingdabaicha and RouGui is within the range of 4β158.88~14β849.11βkPa, the maximum stess is within the range of 870.00~1β842.97βkPa, the fracture stress is within the range of 673.33~1β639.62βkPa, the influence of leaf position to modulus of elasticity, maximum stess and breaking stress is highly significant. third leaf >second leaf> first leaf. The maximum strain of tea shoots is within the range of 10.61%~18.36%, the fault strain is within 12.19%~26.95%, the leaf position shows a highly significant effects on the maximum stain and breaking strain, and the order as follows: third leaf>second leaf>first leaf, there are some differences between different cultivars.

Key words: modules of elasticity, fracture stress, leaf position, mechanical properties
