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 reinforced panel and a manufacturing method thereof and belongs to the field of automobile parts. The automobile B-pillar reinforced panel comprises a reinforced panel outer shell and an inner layer stiffening plate, wherein an open groove is formed in the middle part of the reinforced panel outer shell. The inner layer stiffening plate is fixed in the open groove of the reinforced panel outer shell and is made of carbon fibre composite material. The automobile B-pillar reinforced panel has the advantages that the space, on the reinforced panel outer shell, occupied by the inner layer stiffening plate is reduced; strong shock resistance, high strength and light mass are realized; the automobile B-pillar reinforced panel is guaranteed to be uneasy to deform when the side surface of an automobile body suffers a collision so that injuries of people in the automobile are avoided; and meanwhile, an automobile door can be normally opened to ensure that the people in the automobile smoothly escape.

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...
