Abstract

The invention relates to the field of bionic layered composite materials, in particular to a micron and nano material-enhancing high-impact-resistance bionic layered composite material and a manufacturing method thereof. The material provided by the invention is formed in a manner that toughening structural material layers and enhancing material layers are composited at intervals layer by layer, and the outer layers on both faces of the bionic layered composite material are the enhancing material layers; and the toughening structural material layers are continuous fiber structural bodies formed through interweaving continuous fibers, or non-interweaved continuous fiber structural bodies formed by the continuous fibers, and the enhancing material layers are micron and nano inorganic material granular layers obtained in a manner that a mixture formed by mixing micron and nano inorganic material granules with thermoplastic macromolecular resin is coated on the toughening structural material layers. The material provided by the invention is a more-effective lightweight protective material, and some defects, such as low interlayer strength and too large load, caused by too thick composite layers, infirmness of interlayer bonding, and the like, in the prior art are overcome.

Description

technical field [0001] The invention relates to the field of bionic layered composite materials, in particular to a bionic layered composite high impact resistance material reinforced by micron and nanometer materials and a preparation method thereof. Background technique [0002] Impact-resistant materials are widely used as protective materials in security, anti-terrorist attacks and wars in modern society. According to its use, impact-resistant materials can be divided into ordinary impact-resistant materials and advanced impact-resistant materials. Ordinary impact-resistant materials are generally used in people's livelihood, such as diving suits, mountaineering suits, construction helmets, etc.; advanced impact-resistant materials are generally used in national defense, military and scientific research, such as aviation suits, experimental protective clothing, armor protective equipment and many more. However, due to the development of modern technology, the requireme...
