Abstract
The invention relates to the technical field of composite materials, in particular to a composite material forming vacuum bag film and an air bag with exhaust and flow guide functions.
Description
Technical Field
The invention relates to the technical field of composite materials, in particular to a composite material forming vacuum bag film with exhaust and flow guide functions and an air bag.
Background
All will use vacuum bag membrane or gasbag in carbon-fibre composite forming process, form certain intensity after vacuum bag membrane or gasbag are blown, then pile up composite such as carbon fiber on vacuum bag membrane or gasbag surface, in the use in the past, vacuum bag membrane or gasbag surface and carbon-fibre composite's cooperation department are the easy overstocked air, and the overstocked air causes carbon-fibre composite's surface easily to have the bulge or cave in, great influence the quality of product.
Disclosure of Invention
In order to solve the defects and problems in the forming of the carbon fiber composite material in the prior art, a composite material forming vacuum bag film with exhaust and flow guide functions and an air bag are provided.
The technical scheme adopted by the invention for solving the technical problem is as follows: the invention relates to a composite material forming vacuum bag film with exhaust and flow guide functions and an air bag.
The diversion trench is formed by molding a die.
The diversion trench is formed by an extrusion forming machine.
The invention has the beneficial effects that: compared with the prior art, the composite material forming vacuum bag film with exhaust and flow guide and the air bag have the advantages that the flow guide groove is formed in the surface of the bag film or the air bag, air between the bag film or the air bag and the accumulation layer is exhausted through the flow guide groove, the smoothness and the flatness of the surface of the carbon fiber composite material are guaranteed, and the quality of a product can be greatly improved.
Drawings
The composite material forming vacuum bag film and the air bag with exhaust and flow guide of the invention are further described with reference to the accompanying drawings and the specific embodiments.
FIG. 1 is a schematic structural view of a composite material formed vacuum bag film and an airbag with exhaust and flow guide functions according to the present invention.
The specific implementation mode is as follows:
as shown in figure 1, the composite material forming vacuum bag film and the air bag with the exhaust and flow guide functions comprises a bag film or an air bag 1, wherein a flow guide groove 2 is arranged on the surface of the bag film or the air bag 1, and the flow guide groove 2 covers the surface of the bag film or the air bag 1. The diversion trench 2 can be formed by drawing a die, and when the bag film or the airbag 1 is formed, a trench is arranged on the die, so that the bag film or the airbag 1 naturally forms the diversion trench 2 after the die is drawn out. The diversion trench 2 can also be formed by extrusion molding of an extrusion molding machine, namely after the bag film or the air bag 1 is molded, the bag film or the air bag 1 is placed on a pressing plate mold to be pressed into a row of small grooves, so that the diversion trench 2 is formed. When the carbon fiber composite material is wrapped on the surface of the bag film or the air bag 1, air at the matched part is led out through the diversion trench 2, and the overstocked carbon fiber composite material cannot be influenced due to the fact that the diameter of the diversion trench 2 is small, and the bag film or the air bag 1 adopting the diversion trench 2 is particularly suitable for a forming body with a long length.
In summary, compared with the prior art, the composite material forming vacuum bag film and the air bag with exhaust and flow guide of the invention have the advantages that the flow guide groove is arranged on the surface of the bag film or the air bag, air between the bag film or the air bag and the accumulation layer is exhausted through the flow guide groove, the smoothness and the flatness of the surface of the carbon fiber composite material are ensured, and the quality of a product can be greatly improved.
The present invention has been described in accordance with embodiments thereof with the understanding that the present invention is not limited thereto but rather it is to be understood that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims, and any such modifications, equivalents and the like as fall within the true spirit and scope of the invention.
Claims (3)
1. The utility model provides a compound material shaping vacuum bag membrane and gasbag with exhaust water conservancy diversion which characterized in that: the bag film or the airbag is provided with a diversion trench on the surface, and the diversion trench is formed on the surface of the bag film or the airbag.
2. The composite material forming vacuum bag film and the air bag with exhaust and flow guide functions as claimed in claim 1, wherein: the diversion trench is formed by molding a die.
