Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation.
This carbon fibre composite skylight of the present invention reinforces plate producing process, as shown in figure 3, include the following steps, it is accurate
Standby carbon fibre composite prepreg；Prepreg is cut and integral is coated with shape；Mold pre-treatment；By the prepreg after cutting
Layering is coated on mould surface from level to level；Outside is coated with vacuum bag, vacuumize process after prepreg is coated with；It is whole after being coated with
It is sent into autoclave heat-pressure curing；Cooling and demolding processing.Its material, by different angle laying, is adopted using carbon fiber prepreg
The structure being molded with autoclave process, production process use automatic blanking machine fabric dividing, manual laying, good product quality, property
It can be high.
In the present invention, it is coated with using middle layer as symmetrical centre both sides laying angle symmetrical.
Prepreg after cutting is integrally coated with 17 layers, and 0 ° of direction is coated with 5 layers, and 45 ° of directions are coated with 4 layers, and -45 ° of directions are coated with 4
Layer, 90 ° of directions are coated with 4 layers.
Every layer of prepreg thickness is 0.13-0.16mm.
The 9th layer of centre and the laying direction of setting are in 0 ° of laying, from middle layer to both sides by 90 °, -45 °, 0 °, 45 ° of pavings
Layer angle sequence is coated with.
- 0.1Mpa is evacuated in step 4).
Step 5) hot pressing pressure tank is 0.4-0.6Mpa, heats 70-90 DEG C and maintains 30 minutes, then is warming up to 120-140 DEG C
It maintains 120 minutes.Autoclave forming process, high temperature, the molding of the high pressure field of force, product quality and performance higher.
Operating mode and performance requirement are actually used according to skylight reinforcing plate, the general rule of material Lay up design are answered in conjunction with carbon fiber
Model need to be designed to isotropism.By CAE analysis meet performance requirements, lightweight requirements, actual operation requirements and at
In the case of type technological requirement, and meet the electrochemical corrosion requirement of surface and metalwork, product is avoided to deform and turn round
The defects of bent, is coated with using whole.
Carbon fibre composite skylight of the present invention reinforces plate producing process, during laying, is coated with, i.e., will using whole
Prepreg cut it is integral is coated with shape, set on paving face and be coated with origin 3 and be coated with direction 4, by setting be coated with angle into
Row laying.Entirety, which is coated with, follows laying angle symmetry principle, it then follows ± 45 ° principle occur in pairs, it then follows equidirectional layer number is not
More than 60% principle of total number of plies, the defects of to enhance reinforcing plate structural strength, product avoided to deform and distort.With under product
Surface is that patch die face is coated with, and patch die face refers to that layer of structure contacted with metal die.Using product outermost boundary as
The paving boundary 2 of engineering boundary.
An embodiment of the present invention, it is to be coated with origin 3 to build out coordinate origin in piece surface.Y-axis is selected to be spread as 0 °
Cover direction 4.Laying scheme is as follows：Skylight reinforcing plate is integrally coated with 17 layers, and laying thickness in monolayer is 0.145mm, and overall thickness is total
2.465mm.0 ° of direction is coated with 5 layers, accounts for total layer：29.41%.45 ° of directions are coated with 4 layers, account for total layer：23.53%.- 45 ° of direction pavings
4 layers are covered, total layer is accounted for：23.53%.90 ° of directions are coated with 4 layers, account for total layer；23.53%.
Using automatic blanking machine fabric dividing, manual laying, using prepreg die press technology for forming, autoclave forming process is high
Temperature, the molding of the high pressure field of force, product quality and performance higher.During entire solidification, to ensure Product Process stability and continuing
Monitoring, the measuring temperature time interval for recording each thermocouple are no more than 10 minutes.
Carbon fibre composite skylight of the present invention reinforces plate producing process, meets performance requirements, lightweight requirements, reality
Border requirement and moulding process requirement, the skylight reinforcing plate produced is specifically light-weight, and intensity is high, corrosion-resistant, damping good
The advantages that.Using autoclave forming process, the carbon fiber product of higher quality and performance has been obtained, has been added compared to conventional metals skylight
Strong plate, 40% or more loss of weight, light weight effect is apparent, has preferable application prospect.
Above in conjunction with attached drawing, the present invention is exemplarily described, it is clear that the present invention implements not by above-mentioned side
The limitation of formula, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is used, or without
It improves and the design of the present invention and technical solution is directly applied into other occasions, within protection scope of the present invention.
