Abstract

The invention discloses a preparation method of a bionic shell material, and belongs to the technical field of bionic structural mechanics materials. The preparation method comprises the following steps of (1) carrying out construction of brick-wall structure by using modeling software; (2) taking a photosensitive resin as a raw material, adding a diluent and a photoinitiator, and printing an organic framework of a shell structure by adopting micro-nano 3D printing equipment; (3) depositing calcium carbonate in the printed organic framework by adopting an in-situ precipitation method to obtainthe organic framework for depositing calcium carbonate; and (4) carrying out hot pressing on the organic framework deposited with the calcium carbonate by virtue of a hot pressing method to obtain the bionic shell material. The preparation method is simple in process, the prepared bionic shell material is good in uniformity, the strength and fracture toughness property of the prepared bionic shell material are close to that of the shell material, the bionic shell material has very practical value in the fields of mechanical engineering, aerospace, bullet-proof armor and the like.

Description

technical field

[0001] The invention belongs to the technical field of bionic structural mechanics materials, and in particular relates to a preparation method of a bionic shell material. Background technique

[0002] In recent years, biomimetic materials have aroused extensive research interest in the scientific community because of their excellent various properties. Among them, the shell, as the shell of the mollusk near the water, is a calcification formed by the secretion of a special glandular cell of the mollusc, which has the function of protecting the animal body.

[0003] Due to the unique "brick-wall" structure, the shell has excellent strength, stiffness, hardness and strong fracture toughness, and is an ideal bionic model. The structure of shells is usually composed of overlapping layers of lamellae. The main component of the inorganic lamellar structure is CaCO 3 , provides the strength properties of the shell, while the organic protein of the amorphous stru...
