【摘要】 研究了腹足纲香螺贝壳在生长过程中不同时期的壳体材料结构及力学性能。结果表明,随着贝壳的长大,贝壳文石板片厚度增大,各项力学性能指标也随之提高。贝壳体在生长过程中通过软体组织修改所产生的结构和贝壳的性能也在随之而演变。贝壳类天然生物材料的性能不同于传统工程材料中组织特征尺寸越小强度越高的准则,需要考虑贝壳材料本身的微观结构、组成和界面等多方面因素。更多还原

【Abstract】 The microstructures and mechanical properties of the gastropod shell of Hemifusus tuba during different growing periods were studied.The results show that the thickness and mechanical performance of the aragonite fiber increase with the accretion of Hemifusus tuba shell.Thus the mollusk shell alters the microstructure through the soft tissue in the growth process and the structure of mineral and mechanical performance of mollusk shell varies.The mechanical properties of mollusk shells are affected synthetically by the microstructure,organic matrix and some other factors,which are different from the higher strength and little dimension of the traditional engineering material.更多还原
