Abstract
The invention relates to a dry process for forming an arc-shaped continuous fiber composite board. The process comprises the following steps of: preparing a required fiber yarn flock, and unfolding the fiber yarn flock, so that the fiber yarn flock are distributed uniformly to form silk bundles of which the widths are 90 to 120 millimeters; impregnating the silk bundles into resin; after the silk bundles are completely impregnated, baking the silk bundles to obtain fiber preimpregnated cloth; performing pultrusion on the fiber preimpregnated cloth to form an arc-shaped product; and curing the arc-shaped product to obtain a finished product. According to the process, the impregnation process and the pultrusion process are separated, namely the impregnation process is independent, so that the impregnation speed is improved greatly, the requirement on the manufacturability of the resin is reduced, and the resin with high mechanical properties and slightly low manufacturability can be selected; and during pultrusion, the impregnation process is eliminated, so the problem of low long-term applicability of the resin is solved, the quality stability of the product is improved, a process for replacing the resin by workers at regular time is also eliminated, and a production site is clean and tidy.
Description
Technical field
the present invention relates to field of compound material, particularly relate to a kind of dry-press process technology of arc continuous fiber composite material plate.
Background technology
Along with constant development of economy, medical industry also improves the requirement of Medical Devices gradually
, and medical device is required to multifunction, high reinforcement, miniaturization, lightweight, stable words development.It is too heavy that a lot of steel constructions seem under the situation of proof strength.And carbon fibre composite has advantages such as light weight, intensity is high, thermal coefficient of expansion is low, corrosion-resistant, can solve the problem of equipment lightweight, miniaturization, and the particularly development in pluralism of carbon fiber product gets more and more people's extensive concerning.But present pultrusion preparation technology produces to linear pattern, uiform section product, has limited the application of product.
Summary of the invention
the object of the invention provides a kind of dry-press process technology of arc continuous fiber composite material plate.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of dry-press process technology of arc continuous fiber composite material plate, it may further comprise the steps:
(1), impregnation:
Prepare required silvalin group, described silvalin is rolled into a ball launched, evenly be scattered in the wide tow of 90-120mm that is; Described tow is carried out the resin impregnation; , described tow toasts and makes fiber preimpregnation cloth after soaking into fully;
(2), pultrusion:
Pultrusion camber goods are carried out with described fiber preimpregnation cloth in
; Described arc goods are cured, and solidification temperature is 150-200 ℃, and makes finished product.
preferably, the humidity of described silvalin group is less than 50%.
preferably, make described fiber preimpregnation cloth after, its two faces are carried out the covering of diaphragm, and rolling.
preferably, in the pultrusion process, described fiber pre-preg cloth is respectively through 3 humidity province: 70-90 ℃, 120-140 ℃ and 120-140 ℃.
Described tow 110-130 ℃ of baking in back 2-4 minute preferably soaked into fully in
; Perhaps 70-90 ℃ was toasted 2-4 minute, was adjusted to 100-120 ℃ and toasted 2-4 minute again.
preferably, described diaphragm is the PET mould release membrance.
preferably, described silvalin group adopts carbon fiber.
preferably, described resin adopts epoxy resin.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
1, impregnation and pultrusion separate among the present invention, and impregnation is listed separately, and impregnation speed promotes greatly, have reduced the technological requirement of resin, can choose the mechanical property excellence and the poor slightly resin of manufacturability;
Removed gum dipping process when
2, pultrusion: need not consider the long-time applicability problem of resin on the one hand, the stability of product quality improves; Also saved the workman on the other hand and regularly changed the resin operation, the production scene is neat and tidy more also.
Description of drawings
Accompanying drawing 1 is the equipment sketch map of gum dipping process of the present invention;
Accompanying drawing 2 is the equipment sketch map of pultrude process of the present invention;
accompanying drawing 3 is mould--the schematic top plan view of pulling equipment in the pultrude process equipment of the present invention.
wherein: 1, creel; 2, exhibition yarn equipment; 3, impregnation equipment; 4, post processing baking oven; 5, equipment for coating film; 6, rolling equipment; 7, mould; 8, back curing oven; 9, pulling equipment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
are existing to be example to produce the arc carbon fiber composite panel, its wide 100mm, thick 1.4mm.
The carbon filament of the eastern UTS50 of nation that fiber uses, resin system is epoxy-resin systems AS2-02, wherein:
The east UTS50-12K of nation:
Hot strength: 4900 MPa,
Stretch modulus: 240GPa,
Density: 1.8 g/cm3,
Filament diameter: 6.9 μ m;
Epoxy-resin systems AS2-02:
Hot strength: 60-80 MPa,
Heat distortion temperature: 200-220 ℃,
Bending strength: 100-130 MPa,
elongation at break: 3-5%.
Impregnation equipment comprises: creel 1, exhibition yarn equipment 2, impregnation equipment 3, post processing baking oven 4, equipment for coating film 5 and rolling equipment 6;
extruding equipment comprises: mould 7, back curing oven 8 and pulling equipment 9.
(1), impregnation: as shown in Figure 1:
A, on creel 1, place required carbon fiber yarn group, humidity>=50% needs to introduce dehumidification equipment, to guarantee the mass dryness fraction of carbon fiber yarn group;
B, carbon fiber yarn are through exhibition yarn equipment 2, and evenly distributing becomes the tow of wide 105mm;
C, configuration AS2-2 resin are poured impregnation equipment 3 into, and carbon fibre tow soaks into through impregnation fully;
D, soak into carbon fibre tow fully and get into post processing baking oven 4,120 ℃ of bakings 3 minutes; Perhaps 80 ℃ were toasted 3 minutes, were adjusted to 110 ℃ and toasted 3 minutes again, made carbon fibre initial rinse fabric;
E, back through 6 rollings of rolling equipment by the two sides covered with protective film (PET mould release membrance or other) of 5 pairs of carbon fibre initial rinse fabrics of equipment for coating film;
