The textile filler further contains a layer (4) of synthetic fibres provided, at least, at one of the surfaces, the said layer (4) is either glued to an outer surface of the complex (1, 2, 3) or all layers of the complex (1, 2, 3) are mutually needled.

Description

Oblasť technikyTechnical field

Vynález sa týka zlepšenia textilných výplní na výrobu kompozitných materiálov, t. j. výrobkov na báze živice, polyestru a ďalších, vystužených textilným rúnom.The invention relates to the improvement of textile padding for the production of composite materials, i. j. products based on resin, polyester and others, reinforced with textile fleece.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Vynález sa predovšetkým týka zlepšenia výplni, ktoré sú predmetom francúzskeho vynálezu č. FR-A-2 646 442, ktorého obsah je súčasťou opisu predkladaného vynálezu.In particular, the present invention relates to improvements to the fillers which are the subject of French invention no. FR-A-2 646 442, the contents of which are included in the description of the present invention.

Výplň, ktorá je predmetom spomenutého francúzskeho vynálezu, je tvorená aspoň dvoma textilnými vystužovacími vrstvami, usporiadanými z obidvoch strán centrálnej vrstvy, udávajúcej hrúbku tohto materiálu, pričom je táto centrálna vrstva tvorená rúnom na báze syntetických vlákien, ktoré majú jednotnú vyššiu dĺžkovú hmotnosť a ktoré boli vopred oblúčkované alebo stále skučeravené, vedúca k vytvoreniu ľahkého rúna, objemného a vzdušného. Výhodne sú spojené rôzne vrstvy medzi sebou prešitím/prepletením.The filler object of the French invention consists of at least two textile reinforcing layers arranged on both sides of a central layer indicating the thickness of the material, the central layer consisting of a synthetic fiber web having a uniform higher length weight and having pre-hemmed or still curled, resulting in the formation of a light fleece, bulky and airy. Preferably, the different layers are joined together by stitching / interlocking.

Súčasné textilné vystužovacie vrstvy umiestnené z jednej aj druhej strany centrálnej vrstvy, ktorá udáva materiálu hrúbku, sú výhodne vytvorené z vlákien podušiek, prípadne pripojených k ďalším textilným výstuhám. Výplne vyrobené v súlade s citovaným vynálezom sú obzvlášť upravené na použitie pri postupoch ako je liatie pod tlakom, liatie vstrekom a vákuové liatie.The present textile reinforcement layers located on either side of the central layer, which indicates the thickness of the material, are preferably formed of cushion fibers, optionally attached to other textile reinforcements. Fillers manufactured in accordance with the cited invention are particularly adapted for use in processes such as die casting, injection molding and vacuum casting.

Skonštatovalo sa, že pri určitých aplikáciách má spojenie rôznych vrstiev prešitím/prepletením niekedy za následok povrchové chyby, predovšetkým zo strany retiazkového stehu, ktorý tvorí tieto spoje.It has been noted that in certain applications, the bonding of the various layers by stitching / interlocking sometimes results in surface defects, especially from the side of the chain stitch that forms these bonds.

Zistilo sa však, a toto je práve predmetom vynálezu, že je možné nielen zlepšiť stav povrchu kompozitných materiálov obsahujúcich takéto výplne, ale rovnako upraviť určité technické parametre, ako je priestorová stabilita výrobku, možnosti deformácie podľa potreby príslušného použitia takýchto materiálov.However, it has been found, and this is precisely the object of the invention, that it is not only possible to improve the surface condition of composite materials containing such fillers, but also to adjust certain technical parameters such as spatial stability of the product, deformation possibilities according to the respective use of such materials.

Podstata vynálezuSUMMARY OF THE INVENTION

Všeobecne zlepšenie podľa vynálezu spočíva v tom, že výplň je v podstate typu opísaného v predmete citovaného francúzskeho vynálezu, a teda obsahuje aspoň dve vrstvy spevňovacích textilných vrstiev umiestnených z obidvoch strán centrálnej vrstvy, dodávajúca hrúbku tomuto materiálu, pričom tieto vrstvy sú medzi sebou spojené šitim/pletením, podľa vynálezu však navyše obsahuje aspoň na jednej z obidvoch vonkajších strán rúno zo syntetických vlákien, pripevnený buď prilepením k vonkajšiemu povrchu komplexu alebo prostredníctvom šitia spájajúcich rôzne vrstvy medzi sebou.In general, the improvement according to the invention is that the filler is essentially of the type described in the subject matter of the French invention and thus comprises at least two layers of reinforcing textile layers placed on both sides of the central layer imparting thickness to the material. However, according to the invention, in addition, it comprises, at least on one of the two outer sides, a synthetic fiber fleece, fixed either by gluing to the outer surface of the complex or by means of suturing joining the different layers therebetween.

Centrálne rúno je výhodne na báze syntetických vlákien s väčšou dĺžkovou hmotnosťou a skučeravených podobne, ako pri citovanom vynáleze, ale môže rovnako byť na báze iných hrubých vlákien, napríklad rastlinných vlákien. Toto centrálne rúno má výhodne plošnú hmotnosť medzi 150 g/m2 a 400 g/m2. Totiž pri plošnej hmotnosti menšej ako 150 g/m2 stráca komplex svoju odolnosť a rovnomernosť, zatiaľ čo väčšia hmotnosť ako 400 g/m2 vedie k výrobkom s hrúbkou, ktorá je v praxi neodôvodniteľná. Hrúbka tohto centrálneho rúna býva obyčajne medzi 3 a asi 8 mm.The central web is preferably based on synthetic fibers of greater length and collapsed similarly to the cited invention, but may also be based on other coarse fibers, for example plant fibers. The central web preferably has a basis weight between 150 g / m 2 and 400 g / m 2 . Indeed, at a basis weight of less than 150 g / m 2 , the complex loses its durability and uniformity, while a weight of more than 400 g / m 2 leads to products with a thickness which is unjustifiable in practice. The thickness of this central web is usually between 3 and about 8 mm.

Textilné vystužovacie vrstvy, umiestnené z obidvoch strán centrálnej vrstvy, sú výhodne tvorené sklenenou po duškou, prípadne vystužením textilnou mriežkou, pričom plošná hmotnosť týchto vrstiev je spravidla medzi 300 a 600 g/m2.The textile reinforcement layers placed on both sides of the central layer are preferably formed by glass punch or a textile grid reinforcement, the basis weight of these layers being generally between 300 and 600 g / m 2 .

Výhodné je, ak sa použije rúno zo syntetických vlákien, ktoré má plošnú hmotnosť v rozmedzí 50 a 150 g/m2, pričom vlákna, z ktorých je rúno vyrobené, sú veľmi jemné a majú spravidla dĺžkovú hmotnosť 0,1 až 0,7 g/km, t. j. vlákna omnoho jemnejšie než vlákna použité v kompozícii opísanej výplne. Týmto spôsobom sa docieli to, že povrchové vlákna majú veľmi dobrú homogenitu podporujúcu rozloženie živice počas liatia. Pritom tieto povrchové vlákna zabraňujú značkovaniu týmito hrubými vláknami vnútornej štruktúry.It is preferable to use a synthetic fiber web having a basis weight between 50 and 150 g / m 2 , the fibers of which the web is made are very fine and generally have a length weight of 0.1 to 0.7 g / km, ie fibers much finer than the fibers used in the filler composition described. In this way, it is achieved that the surface fibers have a very good homogeneity promoting the distribution of the resin during casting. These surface fibers prevent marking with these coarse fibers of the internal structure.

Vynález a z neho vyplývajúce výhody budú lepšie badateľné zo štyroch nakreslených a opísaných príkladov uskutočnenia podľa vynálezu.The invention and the resulting advantages thereof will be better understood from the four illustrated and described embodiments of the invention.

Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS

Príklady uskutočnenia textilnej výplne vynálezu sú na obr. 1 až 4, z ktoiých je vidieť štyri základné typy výrobkov.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE TEXTILE FILLING OF THE INVENTION FIG. 1 to 4, from which four basic types of products can be seen.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Štyri výrobky, vytvorené podľa vynálezu zahrnujú základnú štruktúru, vyrobenú v súlade s vynálezom FR-A-2 646 442, ktorá obsahuje:The four articles made according to the invention comprise a base structure made in accordance with the invention FR-A-2 646 442 comprising:

- jednu vnútornú vrstvu 1 pozostávajúcu z netkaného rúna, vytvoreného mykaním polyesterových vlákien, ktoré majú jednotnú dĺžkovú hmotnosť 4 g/km a dĺžku rezu 60 mm, pričom vlákna boli dopredu skučeravené pred narezaním takýmto spôsobom, ktorým vznikne stála oblúčkovitosť - v tomto prípade 2,3 oblúčikov na centimeter, toto rúno má plošnú hmotnosť asi 250 g/m2 a hrúbku asi 5 mm;- one inner layer 1 consisting of a nonwoven web produced by carding polyester fibers having a uniform length of 4 g / km and a cutting length of 60 mm, the fibers being crimped prior to cutting in such a way as to produce a permanent curvature - in this case 2, 3 arches per centimeter, the web having a basis weight of about 250 g / m 2 and a thickness of about 5 mm;

- dve vystužovacie textilné rúna 2, 3 sú umiestnené z obidvoch strán vnútornej vrstvy 1, pričom tieto vystužovacie textilné rúna 2, 3 sú obe tvorené sklenenou poduškou s plošnou hmotnosťou 450 g/m2, získanou narezaním sklenených vlákien a klasickým vrstvením suchou cestou, tieto sklenené vlákna majú dĺžkovú hmotnosť aspoň 2,5 g/km, pričom dĺžka rezu je 50 mm.- two reinforcing textile webs 2, 3 are placed on both sides of the inner layer 1, these reinforcing textile webs 2, 3 being both a glass cushion having a basis weight of 450 g / m 2 , obtained by cutting glass fibers and by classical dry-layering, the glass fibers have a length of at least 2.5 g / km, the length of the cut being 50 mm.

Podľa vynálezu je aspoň k jednej z vonkajších plôch tejto základnej konštrukcie pripojené rúno 4 zo syntetických vlákien. Toto rúno 4 alebo tieto rúna 4 zo syntetických vlákien môžu byť buď prilepené k exteriéru trojvrstvového komplexu spojenému šitím/pletením alebo môžu byť priložené z jednej či z obidvoch vonkajších strán komplexu ešte predtým, než boli vrstvy spojené šitím/pletením.According to the invention, a synthetic fiber web 4 is attached to at least one of the outer surfaces of this basic structure. The web 4 or these synthetic fiber webs 4 may either be glued to the exterior of the three-layer complex by sewing / knitting bonded or may be applied from one or both of the outer sides of the complex before the layers are sewn / knitting bonded.

V príklade uskutočnenia nakreslenom na obr. 1 je pripevnený k vonkajšej vystužovacej vrstve 2 jediné rúno 4, tvorené polyesterovými vláknami, ktorých dĺžková hmotnosť je 0,1 až 0,7 g/km a plošná hmotnosť medzi 50 a 150 g/m2, pričom tieto dve vrstvy spolu sú zošité polyesterovým vláknom s dĺžkovou hmotnosťou 17,6 g/km.In the embodiment shown in FIG. 1 is fastened to the outer reinforcing layer 2 by a single web 4 made of polyester fibers having a length of 0.1 to 0.7 g / km and a basis weight between 50 and 150 g / m 2 , the two layers being sewn together with polyester fiber with a length of 17.6 g / km.

V porovnaní s komplexom uskutočneným podľa citovaného francúzskeho vynálezu č. FR-A-2 646 442, ktorý neobsahuje polyesterové rúno, získa sa pri výrobe kompozitného materiálu lepší stav povrchu. Z iného hľadiska má ešte taká konštrukcia lepšiu priestorovú stabilitu a menej sa deformuje.Compared to the complex according to the cited French invention no. FR-A-2 646 442, which does not contain a polyester fleece, provides a better surface condition in the manufacture of the composite material. In another aspect, such a construction still has better spatial stability and less deformation.

Na obr. 2 je nakreslený ďalší príklad uskutočnenia podľa vynálezu, kde to isté rúno 4 je pripevnené k vonkajšej strane komplexu 1, 2,3, dopredu spojeného šitím/pletením.In FIG. 2, another embodiment of the present invention is illustrated, wherein the same web 4 is attached to the outside of the complex 1, 2, 3, previously stitched / knitted.

V porovnaní s materiálom nakresleným na obr. 1, získa sa rovnako lepší stav povrchu, rovnako ako väčšia možnosť deformácie výrobku.Compared to the material shown in FIG. 1, a better surface condition is obtained as well as a greater possibility of deformation of the article.

V príklade uskutočnenia nakreslenom na obr. 3 sú dve rúna 4 pripojené z obidvoch strán komplexu, pričom je jedno umiestnené na rúne 3 a je prišité, druhé je umiestnené na rúne 2 a je prilepené nad prešitím.In the embodiment shown in FIG. 3, two webs 4 are attached from both sides of the complex, one being placed on the web 3 and being sewn, the other being placed on the web 2 and glued over the suture.

Takýto výrobok umožňuje získanie kompozitného materiálu s vynikajúcim stavom povrchu na obidvoch stranách hotového dielu.Such a product makes it possible to obtain a composite material with excellent surface condition on both sides of the finished part.

Na obr. 4 je nakreslený štvrtý variant, kde dve rúna 4 sú prilepené z obidvoch strán komplexu 1, 2, 3, spojeného prešitím. Získa sa rovnako vynikajúci stav povrchu, rovnako ako veľmi dobré charakteristiky deformácie porovnateľné s charakteristikami materiálu vyrobeného podľa citovaného francúzskeho vynálezu č. FR-A-2 646 442.In FIG. 4 shows a fourth variant wherein two webs 4 are glued from both sides of complex 1, 2, 3 joined by stitching. An equally excellent surface condition is obtained, as well as very good deformation characteristics comparable to those of the material produced according to the cited French invention no. FR-A-2,646,442.

Vynález samozrejme nie je obmedzený na opísané príklady uskutočnenia, ale vzťahujú sa na všetky varianty, uskutočnené v jeho duchu.Of course, the invention is not limited to the described embodiments, but applies to all variations made in its spirit.
