Lambdoidal Reinforced Microstructure of Mactridae Shell
A scanning electron microscope (SEM) was used for observing the microstructures of a Mactridae shell.It showed that the shell is a kind of natural bioceramic composite,which consists of aragonite sheets and organic matrix with laminated structure.It also showed that there are various reinforced microstructures in the shell,which include a kind of lambdoidal one.The maximum pullout force of the lambdoidal reinforced microstructure,which is related to the fracture toughness of the shell,was analyzed and compared with that of a conventional 0°-structure based on their representative models.The result indicated that the maximum pullout force of the lambdoidal reinforced microstructure is markedly larger than that of the 0°-structure,which was experimentally verified.
