Description
Technical field
The present invention relates to composite materials, specifically, being a kind of carbon fiber composite prepared using vinyl ester resin
Expect manufacturing process.
Background technique
Carbon fiber reinforced polymer is high with intensity, property becomes smaller, elasticity modulus is moderate, corrosion-resistant, light, fatigue resistance is excellent
The advantages that different, has been used for building structure reinforcement, seismic hardening etc., and wherein carbon cloth material has a lot of research and application real
Example, Technical comparing is mature, and the intensity of carbon fibre composite is 4-8 times of steel, and modulus is much smaller than close to steel, relative density
Steel, with glass fibre ratio, not only the performances such as intensity, modulus and relative density are more excellent, corrosion resistance, moisture resistance, and alkali resistance resists
It is salt also relatively good with fatigue durability, but China is also less to the mode of other fibre reinforced thermosetting materials.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention discloses a kind of carbon fiber using vinyl ester resin preparation is compound
Material fabrication process prepares carbon fibre composite by vinyl ester resin, not only improves the heat resistance fire resisting of resin matrix
Property, the carbon fiber of higher performance can greatly increase safety coefficient when logical.
To achieve the goals above, the technical solution that the present invention uses is as follows：
A kind of carbon fibre composite manufacturing process prepared using vinyl ester resin is mainly included raw material resin, caused
Agent, release agent, technical process include collection of filaments frame, mesh plate, pre-treatment of carbon fiber, Resin bath, molding die,
First injection resin impregnation tank is mixed evenly, by pultrusion in resin, initiator, release agent by post-processing, dragger in proportion
Technique, carbon fiber form molding die after impregnating resin, across mold, enter back into dragger.
The present invention is further improved, and molding die uses gradient-heated mode, and forming temperature is 80-140 °, to guarantee tree
Rouge curing molding.
The present invention is further improved, and composite material reinforcing rib will carry out the rear curing process in line after mold out, rear to locate
Reason temperature is higher than the glass transition temperature of material.
The present invention is further improved, the pultrusion speed 0.3-0.4m/min in pultrude process, so that carbon fiber volume content
60% or so.
The present invention is further improved, after impregnated carbon fiber resin in mold continuous curing molding, form continuous individual event
Fibrous composite.
The present invention is further improved, and resin, curing agent and release agent are pressed certain 100:2:1.5 weight ratio is mixed
Resin impregnation tank is injected after uniformly, carbon fiber is preprocessed, and continuous curing molding, pretreatment use in mold after impregnating resin
Thermal oxidation mode, processing time are 2 minutes.
Beneficial effects of the present invention：The present invention is the contact area increased with resin, can further improve carbon fiber with
The physical bond ability of vinyl ester resin, at the same thermal oxide surface treatment can in the case where not losing carbon fiber strength,
Increase the binding ability with ethylene polyester resin.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
1- collection of filaments frame in figure, 2- mesh plate, 3- pre-treatment of carbon fiber, 4- Resin bath, 5- molding die, after 6-
Processing, 7- dragger.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be described in further detail, the reality
It applies example for explaining only the invention, protection scope of the present invention is not constituted and limited.
Embodiment：A kind of carbon fibre composite manufacturing process prepared using vinyl ester resin mainly includes former material
Expect that resin, initiator, release agent, technical process include collection of filaments frame 1, mesh plate 2, pre-treatment of carbon fiber 3, resin leaching
Glue groove 4, molding die 5, post-processing 6, first injection is mixed evenly in resin, initiator, release agent by dragger 7 in proportion
Resin impregnation tank 4, by pultrude process, carbon fiber enters back into traction through impregnating resin, the formation molding die 5 after mold
Machine 7.
In this example, molding die use gradient-heated mode, forming temperature be 80-140 °, for guarantee resin solidification at
Type.
In this example, composite material reinforcing rib will carry out the rear curing process in line after mold out, and post-processing temperature is wanted
Higher than the glass transition temperature of material.
In this example, pultrusion speed 0.3-0.4m/min in pultrude process, so that carbon fiber volume content 60% or so.
In this example, after impregnated carbon fiber resin in mold continuous curing molding, form continuous individual event fiber composite
Material.
In this example, resin, curing agent and release agent are pressed certain 100:2:1.5 weight ratio is infused after being mixed evenly
Enter resin impregnation tank, carbon fiber is preprocessed, and continuous curing molding, pretreatment use at thermal oxide in mold after impregnating resin
Reason mode, processing time are 2 minutes.
Basic principles and main features and advantage of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
