Lambdoidal Reinforced Microstructure of Mactridae Shell
A scanning electronic microscope (SEM) was used for observing the microstructures of a Mactridae shell. The observed result shows that the shell is a kind of natural bioceramic composite, which consists of aragonite sheets and organic matrix with laminated structure. The observed result also shows that the aragonite sheets compose various reinforced microstructures, 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 indicates that the maximum pullout force of the lambdoidal reinforced microstructure is markedly larger than that of the 0° structure, which was experimentally verified.
