Problems solved by technology

[0002] At present, the vehicle anti-collision beams used for the front and rear of traffic vehicles have been made of metal plate materials. They are stamped with cold-rolled steel plates to form U-shaped grooves. The metal plates are about 5mm thick, with low strength and poor cushioning effect. It is easy to deform and break, does not absorb energy, and has no protective function; although increasing the thickness of the metal plate can enhance the strength of the anti-collision beam, the cost of the material is high, the weight of the vehicle is increased, and the fuel consumption is increased. The cost is too high, especially on the surface of the metal plate material Smooth, the car rebounds or bounces after impact and causes secondary accidents

Embodiment Construction

[0019] As shown in the figure, the present invention provides a fiber-reinforced composite material anti-collision beam. The anti-collision beam is an integrated structure, including a main body (1) of the anti-collision beam, and a pillar (4) is arranged at each end of the pillar. A connecting plate (3) is provided, and the two anti-collision beam connecting plates are connected with the vehicle frame longitudinal beam. The structure is made of fiber-reinforced resin-based composite light-body material, and adopts a quadrilateral honeycomb porous cavity structure (2). The reinforcing fiber of the fiber-reinforced resin composite material is glass fiber, and the resin used is epoxy resin. The anti-collision beam connecting plate (3) and the vehicle frame longitudinal beam can be connected by bolts.

[0020] A fiber-reinforced composite anti-collision beam is made by molding. First, the reinforcing fiber and resin are mixed in proportion, heated to above the softening point an...

Abstract

The invention belongs to the technical field of automobile auxiliary equipment, and particularly relates to a novel anti-collision beam for vehicles. The invention provides a fiber reinforced composite material anti-collision beam. The anti-collision beam is an integrated member formed by compression molding of a fiber reinforced resin-based composite light weight material, and adopts a honeycombporous cyst cavity structure. The fiber reinforced composite material anti-collision beam can reduce the weight of members, the cushioning performance is strong, the anti-impact performance is strong,and the probability of secondary accident caused by sliding after the collision of the vehicles is effectively reduced; and rust not occurs in wet and rainy weathers, the oxidation, fatigue and corrosion resistance is achieved, and the maintenance cost is low.

Description

technical field [0001] The invention belongs to the technical field of automobile auxiliary equipment, and in particular relates to a fiber-reinforced composite anti-collision beam. Background technique [0002] At present, the vehicle anti-collision beams used for the front and rear of traffic vehicles have always been made of metal plate materials, and U-shaped grooves are stamped with cold-rolled steel plates. The thickness of the metal plates is about 5mm, with low strength and poor cushioning effect. It is easy to deform and break, does not absorb energy, and has no protective function; although increasing the thickness of the metal plate can enhance the strength of the anti-collision beam, the cost of the material is high, the weight of the vehicle is increased, and the fuel consumption is increased. The cost is too high, especially on the surface of the metal plate material Smooth, the car rebounds or bounces after impact and causes secondary accidents. Contents of ...
