Abstract
A bicycle frame is composed of the tubes and jointers, which are connected with each other by ultrasonic welding. Said tube or jointer consists of internal carbon fibre reinforced resin-base plastic tube, middle reticular carbon fibre fabric layer and external weatherable high-strength engineering plastic layer. It features high strength.
Description
Technical field
The present invention relates to a kind of carbon fiber composite material bicycle rack
Background technology
Bicycle rack in the market mainly adopts steel structure or aluminium alloy structure tubing, and the steel structure frame strength is high but heavier, and aluminium alloy bicycle frame is low weight but intensity is poor slightly.
Summary of the invention
The objective of the invention is: a kind of carbon fiber composite material bicycle rack is provided, and this vehicle frame is existing than higher intensity, and weight is lighter again, and outer need not to spray paint just can reach the requirement of light bright in luster, can directly print or pad pasting carries out dressing of a surface.
Technical scheme of the present invention is: a kind of carbon fiber composite material bicycle rack, comprise tubing, joint, and the internal layer of described tubing is that carbon fiber enhancement resin base plastic pipe, middle level are that netlike carbon fiber cloth, skin are the type of anti-marquis high-strength engineering plastic coating.
The further technical scheme of the present invention is: a kind of carbon fiber composite material bicycle rack, comprise tubing, joint, the internal layer of described tubing is that carbon fiber enhancement resin base plastic pipe, middle level are that netlike carbon fiber cloth, skin are the type of anti-marquis high-strength engineering plastic coating; The internal layer of described joint is that carbon fiber enhancement resin base plastic pipe, middle level are that netlike carbon fiber cloth, skin are the type of anti-marquis high-strength engineering plastic coating.
The more detailed technical scheme of the present invention is: a kind of carbon fiber composite material bicycle rack, comprise tubing, joint, the internal layer of described tubing is that carbon fiber enhancement resin base plastic pipe, middle level are that netlike carbon fiber cloth, skin are the type of anti-marquis high-strength engineering plastic coating; The internal layer of described joint is that carbon fiber enhancement resin base plastic pipe, middle level are that netlike carbon fiber cloth, skin are the type of anti-marquis high-strength engineering plastic coating; Described tubing adopts ultrasonic welding to be connected with joint.
Advantage of the present invention is:
1. the present invention adopts the high-strength carbon fiber glass fiber reinforced plastic compound tubing, its structural strength is suitable with the steel structure vehicle frame, but weight has only 2/3rds of steel structure, strength-to-density ratio is higher mutually with aluminium alloy structure, and its weight ratio aluminum alloy is also light, not only but great deal of steel and aluminum alloy materials also can be saved a large amount of energy.
2. the present invention adopts the high-strength carbon fiber glass fiber reinforced plastic compound tubing, skin is coated high-strength engineering plastic, is convenient to adopt ultrasonic welding process, and its welding is not only solid and reliable, and outward appearance need not to spray paint and just can reach the requirement of light bright in luster, can directly print or pad pasting carries out dressing of a surface.
Description of drawings
The invention will be further described below in conjunction with embodiment:
Fig. 1 is the body frame structure for automotive scheme drawing;
Fig. 2 is the pipe structure scheme drawing;
Fig. 3 is the joint design scheme drawing.
Wherein: 1 tubing; 11 carbon fiber enhancement resin base plastic pipes; 12 netlike carbon fiber cloth; 13 type of anti-marquis high-strength engineering plastic coatings (ASA); 2 joints; 21 carbon fiber enhancement resin base plastic pipes; 22 netlike carbon fiber cloth; 23 type of anti-marquis high-strength engineering plastic coatings (ASA).
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of carbon fiber composite material bicycle rack, comprise tubing (1), joint (2), the internal layer of described tubing (1) is that carbon fiber enhancement resin base plastic pipe (11), middle level are that netlike carbon fiber cloth (12), skin are the type of anti-marquis high-strength engineering plastic coating (ASA) (13); The internal layer of described joint (2) is that carbon fiber enhancement resin base plastic pipe (21), middle level are that netlike carbon fiber cloth (22), skin are the type of anti-marquis high-strength engineering plastic coating (ASA) (23); Described tubing (1) adopts ultrasonic welding to be connected with joint (2).
The present invention adopts the high-strength carbon fiber glass fiber reinforced plastic compound tubing, its structural strength is suitable with the steel structure vehicle frame, but weight has only 2/3rds of steel structure, strength-to-density ratio is higher mutually with aluminium alloy structure, and its weight ratio aluminum alloy is also light, not only but great deal of steel and aluminum alloy materials also can be saved a large amount of energy; The present invention adopts the high-strength carbon fiber glass fiber reinforced plastic compound tubing, skin is coated high-strength engineering plastic, is convenient to adopt ultrasonic welding process, and its welding is not only solid and reliable, and outward appearance need not to spray paint and just can reach the requirement of light bright in luster, can directly print or pad pasting carries out dressing of a surface.
Claims (3)
1. carbon fiber composite material bicycle rack, comprise tubing (1), joint (2), it is characterized in that: the internal layer of described tubing (1) is that carbon fiber enhancement resin base plastic pipe (11), middle level are that netlike carbon fiber cloth (12), skin are the type of anti-marquis high-strength engineering plastic coating (13).
2. carbon fiber composite material bicycle rack according to claim 1 is characterized in that: the internal layer of described joint (2) is that carbon fiber enhancement resin base plastic pipe (21), middle level are that netlike carbon fiber cloth (22), skin are the type of anti-marquis high-strength engineering plastic coating (23).
