Embodiment 1

[0020] to combine Figure 1 to Figure 7 The embodiment of the present invention is described, and a certain type of automobile anti-collision beam is taken as an example for specific description. The carbon fiber reinforced composite material corrugated core sandwich structure automobile anti-collision beam is formed by gluing an upper panel 1 , a corrugated core panel 2 and a lower panel 3 . The upper panel 1, the corrugated core plate 2 and the lower panel 3 are all made of carbon fiber composite materials, the upper panel 1 and the lower panel 3 are formed by hot pressing of a panel mold, and the corrugated core plate 2 is a corrugated core plate mold thermally formed. The upper panel 1, the corrugated core panel 2 and the lower panel 3 are all made of T300 or T700 unidirectional carbon fiber prepreg cloth through a hot press, and the present invention preferably selects T300 carbon fiber prepreg cloth in consideration of cost. , The single layer thickness is 0.14mm. The ...

Embodiment 2

[0023] This embodiment is the manufacturing method of the automobile anti-collision beam with corrugated core sandwich structure of carbon fiber reinforced composite material described in Example 1. This manufacturing method can simultaneously produce the upper panel 1, the corrugated core panel 2 and the lower panel 3, which greatly improves the production efficiency. Specifically include the following steps:

[0024] ①Cutting carbon fiber prepreg: Through CAE analysis, the required number of carbon fiber layers and the optimal size of the anti-collision beam are obtained, and the unidirectional carbon fiber required for the upper panel 1, corrugated core panel 2 and lower panel 3 of the anti-collision beam is calculated Prepreg area, the present invention preferably adopts T300 carbon fiber prepreg. According to the calculation results, cut out the appropriate quantity and size of carbon fiber prepreg.

[0025] ②Lay release cloth and apply release wax: first clean the corr...

Abstract

The invention provides an automobile anti-collision beam of a carbon fiber reinforced composite material corrugated core sandwich structure, and belongs to the field of automobile passive safety. Theautomobile anti-collision beam comprises an upper panel, a corrugated core plate and a lower panel, the cross section of the corrugated core plate is in a corrugated shape, enough rigidity can be provided, and the quality of the anti-collision beam can be reduced as much as possible. The upper panel is connected with the corrugated core plate, and the corrugated core plate and the lower panel areconnected through adhesive. The upper panel, the corrugated core plate and the lower panel all adopt 0-degree, -45-degree, 45-degree and 90-degree mixed alternate layer paving modes, and the respective thickness can be controlled through the number of layers of carbon fiber prepreg. A mold comprises a corrugated core plate male mold, a corrugated core plate female mold and a panel female mold, thecorrugated core plate female mold is also a panel male mold, so that the mold cost and the production time cost can be saved. According to the invention, the lightweight design of the anti-collisionbeam can be effectively realized, and the fuel consumption of the fuel automobile is reduced or the endurance mileage of the electric automobile is increased.

Description

technical field [0001] The invention belongs to the technical field of automobile passive safety, and in particular relates to an automobile anti-collision beam with a corrugated core sandwich structure of carbon fiber reinforced composite material. Background technique [0002] As the country vigorously promotes new energy vehicles, new energy vehicles have developed rapidly in recent years. However, the battery mileage of pure electric vehicles has not made a big breakthrough, and the weight of electric vehicles can be reduced by 10%, and its mileage can be increased by 5.5%. Lightweight has a great effect on electric vehicles. On the one hand, the automobile anti-collision beam is an important part of the front-end structure of the body-in-white. The lightweight design of the anti-collision beam can make an important contribution to the lightweight design of the vehicle. The energy-absorbing parts during the collision must bear the impact load of the collision, absorb th...
