本文从研究温石棉纤维的卷曲构造着手,分析了温石棉纤维中存在结晶应力场的原因。根据原子间结合力(价键力)的大小,计算了温石棉及另外一些纤维矿物的理论抗拉强度(σ_T)。以温石棉为例分析了理论抗拉强度与实测强度(σ_t)存在差异的主要原因。

The Tensile Strength of Chrysotile Fibre Shen Wenhua;Xu JiamiIn the present paper, by beginning with the discussion of chrysotile fibre's cylindrical structure, we analyze the causes of field of crystalline stress ex- isted in the chrysotile fibre. According to the amount of valence bonding force between the atoms, the theoretical tensile strength (σ_T) of chrysotile and some other fibrous minerals has been calculated, Taking chrysotile for example, the principal causes of existed difference between the theoretical and practical tensile strength (σ_t) have been explained.
