Embodiment

[0026] Such as Figure 1 to Figure 6 As shown, an energy-absorbing module made of composite materials for automobiles is provided with two adjacent first basic modules 1 and second basic modules 2 that can be used for frictional energy absorption and structural crushing energy absorption. The first base module 1 and the second base module 2 respectively comprise at least two first base layers 3 and second base layers 4 with an adjacent interface 5, the first base layer 3 and the second base layer at the adjacent interface 5 4 Relatively move under force and break apart structurally. The first base layer 3 and the second base layer 4 respectively include a base material 6 and a reinforcing material 7 arranged in the base material 6, and a flexible layer is provided between the first base layer 3 and the second base layer 4 at the adjacent interface 5. The connecting piece 8, the flexible connecting piece 8 is respectively connected to the reinforcing material 7 in the first ba...

Abstract

The invention discloses an automobile composite material energy-absorbing module, which is provided with at least one group of adjacent basic modules which can be used for frictional energy-absorbing and structurally crushing energy-absorbing. The beneficial effects of the present invention are: step-by-step damage can be achieved, which can make the damage range of the car different under different collision energies, so that when the car is repaired, it only needs to replace the local structure in a targeted manner, reduce the maintenance cost, and can achieve metal The energy-absorbing effect of material energy-absorbing structural parts.

Description

technical field [0001] The invention relates to the technical field of protective materials, and more specifically, to an energy-absorbing module and an energy-absorbing method of an automobile composite material. Background technique [0002] In the automobile anti-collision system, the traditional design is to install an energy-absorbing box between the anti-collision beam and the main structure of the vehicle body. When a low-speed collision occurs, the anti-collision beam will transmit the impact force to the energy-absorbing box, so that the The box is damaged first. When a high-speed collision occurs, the energy-absorbing box transmits energy to the main structure of the vehicle body. In this traditional design, the energy-absorbing structure will be destroyed as a whole when a collision occurs, and the overall replacement is generally performed when repairing. [0003] With the increasing demand for environmental protection and energy saving, the lightweight of auto...
