Menetelmä muovisen vastuslevyn valmistamiseksi ja vastuslevy - Förfarande för framställning av en motstdndsskiva av plast och motständsskiva 5Method of making a plastic resistance plate and a resistance plate - Förfarande för framställning av en motstdndsskiva av plast och motständsskiva 5
Keksintö koskee kuituvahvieteisen muovilevyn valmistusmenetelmää, jossa ainakin eräänä kuituvahvisteena on hiilikuitukangas tai hiilikuitu-nonwoven, jota voidaan käyttää lämpölevynä. On sinänsä tunnettua valmistaa suuria 10 lämpeneviä pintoja esimerkiksi kattolämmitykseen tai lattialämmitykseen. Perinteisesti käytetään vastuksena metallia, jonka jousto-ominaisuudet eivät ole erityisen hyviä. On myös sinänsä tunnettua sijoittaa lämpövastuksia betonivalumuotteihin, jotta valutyö voidaan tehdä myös 15 kylmänä aikana. Ongelmana on kuitenkin ollut aikaansaada sellainen lämpölevy tai lämmitettävä muotti, joka samalla on ollut plastinen.The invention relates to a method of manufacturing a fiber-reinforced plastic sheet, in which at least one of the fiber reinforcements is a carbon fiber nonwoven fabric or a carbon fiber nonwoven which can be used as a heating sheet. It is known per se to produce large 10 heating surfaces for, for example, ceiling heating or underfloor heating. Traditionally, a metal with not very good elastic properties is used as a resistor. It is also known per se to place thermal resistors in concrete casting molds so that casting work can also be done during cold weather. However, the problem has been to provide a heating plate or heatable mold that has been plastic at the same time.
Keksintö perustuu nonwoven-hiilikuitukankaan muovattavuu-20 teen silloin, kun kangas on muovitetun levyn osana.The invention is based on the formability of a nonwoven carbon fiber fabric when the fabric is part of a plasticized sheet.
Keksinnön mukaiselle menetelmälle vastuslevyn valmistamiseksi on tunnusomaista se, että nonwoven-hiilikuidun tai hiilikuitukudoksen kuidut sidotaan toisiinsa kestomuovia 25 sisältävällä muovilla, jolloin saadaan muovattava, sähköllä lämmitettävä levy.The method of manufacturing a resistance sheet according to the invention is characterized in that the fibers of the nonwoven carbon fiber or carbon fiber fabric are bonded together with a plastic containing a thermoplastic material 25, whereby a moldable, electrically heated sheet is obtained.
Keksinnön mukaiselle vastuslevylle on puolestaan tunnusomaista se, että se sisältää nonwoven-hiilikuitu- tai 30 hiilikuitukudoskerroksen, jonka kuidut on sidottu toisiinsa muovilla, josta huomattava osa on kestomuovia niin, että levy voidaan muovata lämmittämällä sitä uudelleen.The resistance plate according to the invention, in turn, is characterized in that it comprises a layer of nonwoven carbon fiber or carbon fiber fabric, the fibers of which are bonded to each other by a plastic, a considerable part of which is a thermoplastic, so that the plate can be molded by reheating.
Joko hiilikuiturainan muodostuksen jälkeen tai valmiille 35 nonwoven-matolle lisätään termoplastista muovia eli kesto-muovia, jolla aikaansaadaan yhtenäinen muovilevy. Hiilikui-tumaton lisäksi voi levyssä olla muina kerroksina muita nonwoven-kuitumattoja tai jopa harvaan kudottuja kuitukan- 2 81709 kaita. Hiilikuitumaton reunaan liitetään sähkösyöttöön tarvittavat metalliliuskat tai muut siihen soveltuvat sinänsä tunnetut liittimet. Tällaista levyä voidaan muovata lämmittämällä sitä joko muotissa paineen alaisena tai 5 ilman. Levyä voidaan lämmittää vaihtelevalla tasavirralla. Näin aikaansaatu kappale voi olla varsin vaihteleva muodoltaan ja sen osa ovi poiketa merkittävästi alkuperäisestä tasosta. Jos sitä käytetään kalusteisiin, on seurattava kansallisia normeja. Luonnollisesti lait ja asetukset 10 rajoittavat lisäksi tuotteen sähkökytkentöjä. Keksintö on ennen kaikkea taloudellisesti ylivoimainen muihin tunnettuihin lämmityselementteihin verrattuna, joilla myös on plastisen muovin ominaisuudet. Nonwovenin tilalla voi olla hiilikuitukudos, mutta lopputuote ei silloin ole yhtä 15 plastinen eikä yhtä halpa. Menetelmä sopii hyvin erilaisten lämmitettävien muottien tekemiseen. Hiilikuitu toimii paitsi lämpöelementtinä myös erittäin soveliaana täyteaineena, koska se lisää lujuusominaisuuksia, on kevyt eikä sisällä tutkaheijastumaa lisäävää metallia. Lämmitysteho 20 on kokeilutuotteella ollut suurimmillaan 24 kW/m2 .Either after the formation of the carbon fiber web or on the finished 35 nonwoven mat, a thermoplastic, i.e., a thermoplastic, is added to provide a unitary plastic sheet. In addition to the carbon fiber nonwoven, the board may have other layers of other nonwoven nonwoven mats or even sparsely woven nonwoven webs. The metal strips required for the power supply or other suitable connectors known per se are connected to the edge of the carbon fiber mat. Such a sheet can be molded by heating it either in a mold under pressure or without it. The plate can be heated with alternating direct current. The body thus obtained can be quite variable in shape and part of the door deviates significantly from the original plane. If it is used for furniture, national standards must be followed. Naturally, laws and regulations 10 also limit the electrical connections of the product. Above all, the invention is economically superior to other known heating elements, which also have the properties of plastic. Nonwoven may be replaced by carbon fiber fabric, but the end product is then neither as plastic nor as cheap. The method is well suited for making various heated molds. Carbon fiber acts not only as a heating element but also as a very suitable filler because it increases strength properties, is light and does not contain metal that increases radar reflection. The heating product 20 has had a maximum of 24 kW / m2 with the experimental product.
