Problems solved by technology

[0005] Since the existing technology reduces the quality of the automobile B-pillar reinforcement plate by sacrificing strength, when the side of the vehicle body is hit, the automobile B-pillar reinforcement plate is more likely to be deformed, which will not only cause injury to the occupants in the vehicle, but also It is easy to make the door cannot be opened normally, resulting in the inability of the occupants to escape

Embodiment 1

[0066] This embodiment provides an automobile B-pillar reinforcement plate, which is manufactured by the following method:

[0067] The DC04 steel is placed in the stiffener shell mold for stamping to obtain a stiffener shell 1 with a thickness of 1.2 mm.

[0068] The carbon fiber composite material is molded by resin transfer molding technology, and the carbon fiber cloth of model T300 is laid into 11 layers in the mold of the inner reinforcement plate, and the laying angles are 90°, 90°, 45°, 0°, -45°, -45°, -45°, 0°, 0°, 45°, 45°. Subsequently, the mold is closed, and the amount ratio of 5.5:4.5 is injected into the mold of the inner layer reinforcing plate, and the epoxy resin and the curing agent of the models EPON135 and EPON1366 are respectively formed to form a cured inner layer reinforcing plate 2. The cured inner layer reinforcing plate 2 was demoulded to obtain an inner layer reinforcing plate 2 with a thickness of 2.2 mm.

[0069] Subsequently, place the inner re...

Embodiment 2

[0075] The DC04 steel is placed in the stiffener shell mold for stamping to obtain a stiffener shell 1 with a thickness of 1 mm.

[0076] The carbon fiber composite material is molded by resin transfer molding technology, and the carbon fiber cloth of the model T300 is laid in 10 layers in the inner reinforcement plate mold, and the laying angles are 90°, 90°, 45°, 0°, -45°, -45°, -45°, 0°, 0°, 45°. Subsequently, the mold is closed, and an epoxy resin and a curing agent of EPON135 and EPON1366 are injected into the inner layer reinforcement plate mold with a dosage ratio of 5:4 to form a cured inner layer reinforcement plate 2. The cured inner layer reinforcing plate 2 is demolded to obtain an inner layer reinforcing plate 2 with a thickness of 2 mm.

[0077] Subsequently, place the inner reinforcement board 2 in the opening groove of the reinforcement board shell 1, and use DP420 adhesive to glue the reinforcement board shell 1 and the inner layer reinforcement board 2 toget...

Embodiment 3

[0079] The DC04 steel is placed in the stiffener shell mold for stamping to obtain a stiffener shell 1 with a thickness of 1.5 mm.

[0080] The carbon fiber composite material is molded by resin transfer molding technology, and the carbon fiber cloth of model T300 is laid into 12 layers in the mold of the inner reinforcement plate, and the laying angles are 90°, 90°, 45°, 0°, -45°, -45°, -45°, 0°, 0°, 45°, 45°, 45°. Subsequently, the mold is closed, and the amount ratio of 6:5 is injected into the inner layer reinforcing plate mold, and the epoxy resin and curing agent of the models EPON135 and EPON1366 are respectively formed to form a cured inner layer reinforcing plate 2, and the The cured inner layer reinforcing plate 2 is demolded to obtain an inner layer reinforcing plate 2 with a thickness of 2.5 mm.

[0081] Subsequently, place the inner reinforcement board 2 in the opening groove of the reinforcement board shell 1, and use DP420 adhesive to glue the reinforcement boa...

Abstract

The invention discloses an automobile B-pillar reinforcement plate and a manufacturing method thereof, belonging to the field of automobile parts. The B-pillar reinforcement plate of the automobile comprises: a reinforcement plate shell and an inner layer reinforcement plate. Wherein, an opening groove is arranged in the middle part of the reinforcing plate shell. The inner reinforcing plate is fixed in the opening groove of the shell of the reinforcing plate, and the material is carbon fiber composite material. The automobile B-pillar reinforcement plate provided by the invention not only reduces the space occupied by the inner layer reinforcement plate on the reinforcement plate shell, but also makes the automobile B-pillar reinforcement plate have the characteristics of strong shock resistance, high strength and light weight, ensuring When the side of the car body is collided, the B-pillar reinforcement plate of the car is not easy to deform, so as to avoid damage to the occupants of the car, and at the same time, the door can be opened normally to ensure the smooth escape of the occupants in the car.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile B-pillar reinforcement plate and a manufacturing method thereof. Background technique [0002] The car body is provided with car A-pillar, car B-pillar and car C-pillar sequentially from front to back, to support the car body and protect the occupants in the car. Among them, the B-pillar of the car is located between the front seat and the rear seat of the cockpit, extending from the roof to the bottom of the car, and is generally provided with an integrated reinforcement plate structure, which is called the B-pillar reinforcement plate of the automobile. When the side of the vehicle body is collided, the protective effect of the B-pillar reinforcement plate on the vehicle is particularly important. However, the B-pillar reinforcement plate of the automobile is generally heavy in weight, which cannot meet the weight reduction of the automobile and achieve the purpose of e...
