Problems solved by technology

For synthetic polymer materials, many are too brittle, resulting in insufficient energy absorption, or too strong, causing the sheet-like structure to break when subjected to external forces, ultimately unable to exhibit the true mechanical advantages of the shell structure.

Description

technical field [0001] The invention relates to a TPU modified impact-resistant transparent composite material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] Due to the unique multi-level layered structure, shells in nature naturally have excellent tensile and impact resistance and sufficient toughness. Compared with synthetic composite materials, shells not only have outstanding performance, but also have the advantages of maximizing the use of natural resources and minimizing energy requirements to build complex reinforced structures, so the imitation of shell-like composite materials greatly attracts researchers. eyeball. After exploring the reason for its enhancement, it was found that the structure of the shell is composed of a large number of inorganic nanosheets and adhesive shell substances, which endow the shell with unparalleled mechanical properties through mechanisms such as sliding, bridg...
