Description

The thermoplastic resin plastic that is used for moulded products reaches by its moulded products of making

The present invention relates to a kind of tubulose moulded products of making by fiber-reinforced thermoplastic resin plastics (FRTP), also relate to as the FRTP moulded products material of producing FRTP tubulose moulded products and with the FRTP tubulose moulded products of this FRTP moulded products manufacture of materials.

Can be used to produce FRTP tubulose moulded products for example the FRTP moulded products material of racket framework all know routinely, for example

Cylindrical casing, the thermoplastic resin by will being used for masterbatch for example polyamide and Merlon reel off raw silk from cocoons and become fiber and make the masterbatch fiber; To mix to reel off raw silk from cocoons by the fibrous masterbatch fibre bundle of masterbatch with by the fortifying fibre tow that glass fibre, carbon fiber etc. is formed and become the yarn that the circular section is arranged; This yarn is woven to sleeve pipe; Thereby formation cylindrical casing;

Fully-dipping band, it is to obtain by the thermoplastic resin impregnated fortifying fibre with fusion;

Partly-and the band of dipping, it is by only obtaining at the circumference of fortifying fibre dipping fortifying fibre with thermoplastic resin; And

Folk prescription is to cloth, and it obtains by mixing-braiding fortifying fibre and resin fibre.

Yet, producing with conventional cannula under the situation of FRTP tubulose moulded products, because carbon fibre tow (for example has big De Kesi number, the De Kesi number of carbon fibre tow is 12K), inexpensive because of it, therefore be used as the fortifying fibre tow in the yarn, but this fortifying fibre tow is thick, therefore big diameter is arranged.So the crosspoint around this fortifying fibre forms large space, they can be used as space or many resins part in the FRTP tubulose moulded products.FRTP tubulose moulded products just has the intensity that reduces like this.In addition, because the change of the crosspoint of fortifying fibre is many, therefore be difficult to flood this fortifying fibre equably with resin.So so the FRTP tubulose moulded products that obtains has the shortcoming of outward appearance, because it is to wrinkling and many resins sensitivity.

Under the situation of using traditional yarn, because this yarn is thick, diameter is big, and sleeve pipe therefrom is just thick, and the weight of per unit length is also big.Therefore, when hope had FRTP tubulose moulded products in light weight, that intensity is high, for example the racket framework only can be provided with about three layers of sleeve pipe, and like this, design freely is restricted and intensity can not be satisfactory.

In addition, when by weaving conventional yarn when making sleeve pipe, become fine, soft fur and being worn of fortifying fibre.In the case, just the problem that is lowered from the intensity of fortifying fibre generation micronic dust and gained FRTP tubulose moulded products is arranged.

So the band of above-mentioned thorough impregnation is that FRTP itself is not soft because of it.Therefore, be difficult to bring the making sleeve pipe by the braiding thorough impregnation.In addition, in the production of FRTT tubulose moulded products, twine shallowly or the like, be difficult to the band of thorough impregnation is wound on the core material according to long filament.

Above-mentioned part-impregnated tape can be quite soft.Yet it is very expensive, and therefore the FRTP tubulose moulded products that is obtained by it is also expensive.In addition, the band of some parts dipping is not soft, be difficult to so hard band production casing and be difficult to by above-mentioned complete-similar fashion of impregnated tape is wound into this band on the core material.

Above-mentioned folk prescription is very expensive to cloth.Use this folk prescription to be difficult to use the resinous fiber-impregnated fortifying fibre to cloth.When mixed weaving fortifying fibre and resin fibre, this fortifying fibre fine, soft fur that become.

Below explain first embodiment of FRTP tubulose molded article according to the present invention.

Fig. 1 demonstration is used in one of the list that is used for the FRTP moulded products among first embodiment example.This list 1 that is used for the FRTP moulded products has the thin and flat structure of laminate 4, wherein being placed on 2 rotations of shape fortifying fibre tow is used to provide between the thermoplastic resin film of matrix resin, this thermoplastic resin film is wideer than band shape fortifying fibre tow 2, and wherein thermoplastic resin film 3.3 in the edge of laminate 4 part 5,5 fusions, it is along the longitudinal direction of this laminate 4.

Band shape fortifying fibre tow 2 is thin and flat, can obtain it by the fortifying fibre tow that launches to have circular cross-section, for example obtains it from the carbon fiber rove with 800 De Kesi numbers (the long filament number is 12K).The preferred thickness of band shape fortifying fibre tow 2 is to be not more than 1mm, more preferably no more than 0.5mm.The width of band shape fortifying fibre tow 2 and the ratio of its thickness preferably are not less than 4, more preferably are not less than 10.Band shape fortifying fibre tow 2 is made by fortifying fibre (they can be aramid fiber, glass fibre, carbon fiber or the like).

The thickness of each thermoplastic resin film 3 preferably is not more than 100 μ m, more preferably no more than 50 μ m.Its width will be enough to be placed on thermoplastic resin film 3 when band shape fortifying fibre tow 2, prevent in the time of between 3 with the edge part 5 of shape fortifying fibre tow 2 from laminate 4,5 come off, and this width will be enough to connect this thermoplastic resin film in the edge of this laminate 4 part 5,5.

For example make by polyamide, Merlon, polyphenylene oxide and PEI by thermoplastic resin for thermoplastic resin film 3.

Thermoplastic resin film 3 preferably has many pore (not shown).The size of pore is in about 100 μ m-1mm diameter ranges.The degree of distribution of these pores is about 1-50 hole/cm ²

(this sleeve pipe prepares by the list that braiding is used for the FRTP moulded products when forming FRTP tubulose moulded products with sleeve pipe by vacuum drawing, and this material is the thermoplastic resin film 3 from this pore is arranged, 3 obtain), the air that is retained in the band shape fortifying fibre tow 2 can be discharged into the list outside that is used for the FRTP moulded products by this pore; So space that in the FRTP tubulose moulded products that so obtains, does not stay.

The list 1 that is used for the FRTP moulded products has and preferably is not more than 1mm, more preferably no more than the thickness of 0.5mm.This ratio of width and its thickness that is used for the list 1 of FRTP moulded products preferably is not less than 4, more preferably is not less than 10.

In the formation of the list 1 that is used for the FRTP moulded products, the weight ratio of 2 pairs of thermoplastic resin films 3 of band shape fortifying fibre tow is not limited especially; Yet it will be limited according to the volume required content (VF) of fortifying fibre 1 in the FRTP tubulose moulded products.In addition, the De Kesi number of band shape fortifying fibre tow 3 also will suitably limit according to this VF value.

Fig. 2 shows is one of the production equipment example that is preferred for the list 1 of FRTP moulded products in the production drawing 1.

In Fig. 2, the elementary feeding roller of reference number 11 expressions is twining band shape fortifying fibre tow 2 thereon;

Reference number

12a and 12b represent a pair of secondary feeding roller, are twining

thermoplastic resin film

3,3 thereon respectively; The elementary deflector roll of reference number 13 expressions;

Reference number

14a and 14b represent a pair of secondary deflector roll; Reference number 15 expressions one hot-rolling; Reference number 16 expressions one silica gel roller; With reference to 17 expressions, one takers-in.

Use the process units shown in Fig. 2, according to the following steps production list that is used for the FRTP moulded products 1 as shown in fig. 1.

At first, band shape fortifying fibre tow 2 feeds to elementary deflector roll 13, then to secondary deflector roll 14a, the space between the 14b from elementary feed roller 11.Simultaneously,

thermoplastic resin film

3,3 is from

secondary feed roller

12a, and 12b feeds to secondary deflector roll 14a, and the space between the 14b forms pressure lamination member 4 thereby will be with shape fortifying fibre tow 2 vertically to be placed between these

thermoplastic resin films

3,3.

Then, the space between heated hot-rolling 15 and the silica gel roller 16 under these pressure lamination member 4 feeding pressure.Correspondingly, because two edge parts 5 of this pressure lamination member 4,5 do not contain heat-insulating fiber are provided, so

thermoplastic resin film

3,3 are easy to fusion at these positions, so obtain being used for the list 1 of FRTP moulded products, the band shape fortifying fibre tow 2 that wherein is positioned at middle part 6 is not with the thermoplastic resin thorough impregnation that constitutes

thermoplastic resin film

3,3.

Fully soft for the list 1 that is used in the FRTP moulded products, preferably be not higher than 50% fortifying fibre by thermoplastic resin impregnated.In addition, preferably be adhered to the there near fortifying fibre by fusion at least, because fortifying fibre is easy to by alignment with

thermoplastic resin film

3,3 contact surfaces.

At last, the list 1 that is used for the FRTP moulded products is sent to the chill roll (not shown) from the space between hot-rolling 15 and the silica gel roller 16, and on it, the list 1 that is used for the FRTP moulded products is cooled to room temperature, is batched on the takers-in 17 subsequently.

Because the list 1 that is being used for the FRTP moulded products, thin band shape fortifying fibre tow 2 is placed on the thermoplastic resin film 3 of the broad that matrix resin is provided, therefore between 3, when the list 1 that is used for the FRTP moulded products is thermoformed into FRTP tubulose moulded products, be desirable with thermoplastic resin impregnated fortifying fibre; Correspondingly, owing to wrinkling and many resins seldom occur, therefore can obtain having the tubular moulded products of FRTP of good appearance, in addition, all can easily produce, put down owing to it is thin from the list 1 that is used for the FRTP moulded products for sleeve pipe, cloth or prepreg that long filament twines, therefore it is soft as band shape reinforcing fiber bundles 2, it is placed on the middle part 6 of pressure lamination member 4, is not configured the thermoplastic resin thorough impregnation of

thermoplastic resin film

3,3;

Thermoplastic resin film

3,3 delamination are because they have been melted in the edge of pressure lamination member 4 part 5,5; And fortifying fibre can not separate, because band shape fortifying fibre tow 2 is surrounded by

thermoplastic resin film

3,3.

In addition, at the list 1 that is used for the FRTP moulded products by braiding and during production casing, fortifying fibre does not produce fluffing and do not wear and tear yet; Therefore can avoid the generation of fortifying fibre ash and the intensity of gained FRTP tubulose moulding material to reduce.

And because band shape fortifying fibre tow 2 can be obtained by the cheap fortifying fibre with big De Kesi number (for example carbon fibre tow of 12K), the list 1 that therefore is used for the FRTP moulded products is cheap.

Fig. 3 has shown the example of the sleeve pipe that first embodiment is used.This sleeve pipe 20 is columnar, and it is to obtain by the braiding list that is used for the FRTP moulded products 1 as shown in Figure 1.

Because the list 1 that is used for the FRTP moulded products is flat and thin, thereby broad and occupy big area, even therefore use the quality that the number of the tow of big De Kesi number and tow is lowered sleeve pipe 20 can chap; So sleeve pipe 20 can be made into thin and fine and closely woven structure.Correspondingly because the weight of unit length sleeve pipe 20 is little, therefore this sleeve pipe just can than conventional cannula many shop which floor.Therefore, can adjust fortifying fibre, and strengthen design freedom so that for the FRTP tubulose moulded products that is in control from this cover provides desirable intensity.

Fig. 4 explains that first embodiment produces the sketch of one of FRTP tubulose moulded products example.It is the situation of racket framework that this production exemplifies example explanation gained FRTP tubulose moulded products.

At first, as shown in figure 44, several (being 4 among the figure) sleeve pipe 20 coaxial stratification form hollow layer rolled-up stock 21.

Then, shown in Fig. 4 B, the periphery of the pipe of being made by silicon rubber 22 is wrapped by hollow layer rolled-up stock 21.

As Fig. 4 D shown in, with hollow layer rolled-up stock 21, with pipe 22, be placed in the mould 24 that be used to form racket framework thereafter.At this moment, the prepreg that become support component is also put into mould 24.

Then mould 24 is heated above the temperature of the thermoplastic resin fusing point that constitutes thermoplastic resin film 3, so that this thermoplastic resin of fusion and with the thermoplastic resin impregnated fortifying fibre tow 2 of this fusion.During heating, consequently suppressing this hollow layer rolled-up stock is pasting mould 24 air pressure G to be imposed on pipe 22 inside.

After this, when keeping air pressure, mould 24 is cooled off.The pressure that reduces in the pipe 22 takes out product then from mould, just obtain moulded products.

At last, from extracting the pipe 22 desirable FRTP tubulose moulded products that just obtain shown in Fig. 4 D this moulded products out.

Therefore, because (these goods obtain with sleeve pipe 20 in the FRTP tubulose moulded products according to first embodiment, the list 1 that is used for the FRTP moulded products in this sleeve pipe is by braiding), the band shape fortifying fibre tow 2 of the list that is used for the FRTP moulded products of forming sleeves 20 is not only thin but also flat, and therefore the height difference with place, shape fortifying fibre tow crosspoint is very little; Therefore, because the crosspoint is located unappropriated space and is reduced, therefore in product, be difficult to keep the space, so this FRTP tubulose moulded products has outstanding intensity.In addition, this FRTP tubulose moulded products is cheap, because it can obtain from the cheap list that is used for the FRTP moulded products.

Fig. 5 is the sketch that is used to explain the FRTP tubulose moulded products advantage of first embodiment, shown sectional view by the goods that obtain as heating sleeve pipe shown in Figure 3, because heating causes fusion to constitute the thermoplastic resin 3a of thermoplastic resin film 3, and with this thermoplastic resin 3a impregnated tape shape fortifying fibre tow 2.As seen very little in the difference of tow crosspoint height from Fig. 5 with shape fortifying fibre tow 2.

Above-mentioned FRTP tubulose moulded products about according to first embodiment has used the list that is used for the FRTP moulded products in a kind of situation of being explained, and used band shape fortifying fibre tow 2 in this material; Yet the another kind of list that is used for the FRTP moulded products also can use, it contains a laminate and wherein is placed on the shape yarn and is used to provide between the thermoplastic resin film of matrix resin, this film is wideer than band shape yarn, and this thermoplastic resin film is melted along its longitudinal direction at the position, two edges of this laminate.The band shape yarn of Shi Yonging was not only thin but also flat in this case, can be by launching to contain precursor fiber (by the thermoplastic resin preparation) and the rove of fortifying fibre obtains it.

In addition, following band shape fortifying fibre tow 2 can contain the precursor fiber that thermoplastic resin is made.

In addition, the laminated product 4 that is used for the list 1 of FRTF moulded products can be the alternatively laminated product that aforesaid band shape fortifying fibre tow 2 or band shape yarn and being used to provides the thermoplastic resin film of matrix resin.

And, though used hot-rolling, in this process units, also can use belt conveyer or press according to the production example process units of the list 1 of the above FRTP of being used for moulded products.

Produce according to first embodiment in the method for FRTP tubulose moulded products interior pressure is imposed on hollow material, and use sleeve pipe 20, the list 1 that it is used for the FRTP moulded products forms through braiding, yet this FRTP tubulose moulded products can be with various forming method productions, and for example autoclave molding method and long filament twine method.In these methods, use by the cloth of list 1 braiding that is used for the FRTP moulded products or the prepreg that is used for long filament winding method for preparing by the list that is used for the FRTP moulded products.In the case, be smooth like that owing to be used for the list of FRTP moulded products as explained above, so it can easily be wound on the core material.

Explained later is according to second embodiment of FRTP tubulose moulded products of the present invention.

The FRTP tubulose moulded products of second embodiment obtains with different its usefulness wide materials 30 that are used for the FRTP moulded products as shown in Figure 6 that are of first embodiment.

This wide material 30 that is used for the FRTP moulded products is that many by arranging (figure is 6) list that is used for the FRTP moulded products 1 as shown in Figure 1 obtains, the adjacent list 1 that is used for the FRTP moulded products thus, 1 overlaps in such a way mutually, and the edge part 5 that promptly is used for an adjacent list of FRTP moulded products is placed on another edge part 5 in a longitudinal direction; And each the overlapping part 31 that is used for the list 1 of FRTP moulded products all is fused together; Fortifying fibre tow 2 is arranged in parallel thus.

The thickness that is used for the wide material 30 of FRTP moulded products preferably is not more than 1.0mm, more preferably no more than 0.5mm.

Fig. 7-the 9th, some sketches, purpose is to illustrate the process units that is preferred for producing the wide material 30 (as shown in Figure 6) that is used for the FRTP moulded products.
