Abstract

The invention discloses an energy-absorbing 3D printing material, a preparation method thereof, and an energy-absorbing device. The energy-absorbing 3D printing material includes a mixture of tert-butyl methacrylate, aliphatic epoxy acrylate and a photoinitiator, and the tert-butyl methacrylate and aliphatic epoxy acrylate are mixed according to the ratio of the two reactions . The energy-absorbing device is formed by photocuring the energy-absorbing 3D printing material of the present invention. The components of the energy-absorbing 3D printing material in the embodiment of the present invention have good coordination and synergistic effects, a stable dispersion system, and 3D printability, and the material formed after photocuring has excellent stretchability and excellent energy absorption effect. It also has shape memory properties.

Description

Technical field [0001] The present invention belongs to the field of energy-absorbing 3D printing material technology, particularly relates to an energy-absorbing 3D printing material and its preparation method and energy-absorbing device. Background [0002] According to data provided by the World Health Organization, about 1.25 million people die in road traffic accidents worldwide every year, and the main cause of death is the failure of collision protection devices due to violent collisions at too fast speeds. Most of the existing anti-collision protection devices are made of metal materials such as steel or aluminum, but metal materials often have a large weight, which is not conducive to lightweighting and energy saving. In addition, most metal materials have low tensile properties and are limited by existing processing and manufacturing technologies, resulting in low design freedom, which is difficult to exert the energy absorption ability of the material itself, and can o...
