Problems solved by technology

[0004] The purpose of the present invention is to provide a tussah carbon fiber composite helmet based on multi-component coupling bionics and a preparation method. The helmet will not be sunken after being subjected to external force, and the impact force can be effectively absorbed, and the damage area of ​​the helmet can be reduced to the greatest extent. , the advantage of ensuring the safety of the user's head solves the problem that the existing helmet has a single structure and poor impact resistance. After the helmet is subjected to an external force, it is easy to cause the helmet to sag, the damage area of ​​the helmet is large, and the helmet is damaged in severe cases , cannot effectively absorb the impact force, cannot guarantee the safety of the user's head, and there are certain safety hazards

Abstract

The invention discloses a tussah silk carbon fiber composite helmet based on multi-element coupling bionics and a preparation method, the tussah silk carbon fiber composite helmet comprises a helmet shell and multi-element bionic elements, the helmet shell comprises a reinforcing layer, the inner wall of the reinforcing layer is bonded with a tussah silk carbon fiber hybrid composite layer, and the tussah silk carbon fiber hybrid composite layer is bonded with the reinforcing layer. A buffer layer is adhered to the inner wall of the tussah silk carbon fiber hybrid composite material layer, and finally the helmet shell which is wrapped by the reinforcing layer, the hybrid composite material layer and the buffer layer layer by layer is prepared. The multi-element bionic elements comprise an exponential stiffness gradient structure, a cross-scale multi-stage wave interface form, a controllable pore content, size and space distribution structure and a soft and hard collaborative bionic structure. The problems that after an existing helmet is subjected to external acting force, the helmet is prone to being sunken, the helmet is damaged when the external acting force is serious, impact force cannot be effectively absorbed, safety of the head of a user cannot be guaranteed, and certain potential safety hazards exist are solved.

Description

technical field [0001] The invention relates to the technical field of helmets, in particular to an tussah carbon fiber composite helmet based on multi-coupling bionics and a preparation method. Background technique [0002] Helmet is a device to protect the head. It is a hat worn by soldiers in training and combat. It is an indispensable tool in people's transportation. It is divided into military helmets, police helmets and civilian helmets. The shell, lining and suspension device are composed of three parts. The shell is made of special steel, FRP, reinforced plastic, leather, nylon and other materials to resist the damage of warheads, shrapnel and other strikes to the head. [0003] The existing helmet has a single structure and poor impact resistance. After the helmet is subjected to an external force, it is easy to cause a dent in the helmet, and the damage area of ​​the helmet is large. It can ensure the safety of the user's head, and there are certain safety hazards...
