Description
Oppfinnelsen angår sammensatte gjenstander som ut-gjøres av fibre eller filamenter som er agglomerert med en syntetisk harpiks. Eksempler på slike gjenstander er styreratt for kjøretøyer. The invention relates to composite objects which consist of fibers or filaments which are agglomerated with a synthetic resin. Examples of such objects are steering wheels for vehicles.
Slike styreratt er beskrevet f.eks. i franske patenter 1561120 og 7905080 og er av interesse for å gi føreren større sikkerhet i tilfelle av kollisjon. For styrerattet som omfatter den utførelsesform som er beskrevet i fransk patent 790508, er således armene som forbinder navet med omkretsen dannet av agglomererte fibre som er parallelle til hverandre og som absorberer kollisjonsenergien ved at de deformeres progressivt, slik at sår som eventuelt vil kunne påvirke føreren, blir sterkt redusert. Such steering wheels are described e.g. in French patents 1561120 and 7905080 and is of interest to give the driver greater safety in the event of a collision. Thus, for the steering wheel comprising the embodiment described in French patent 790508, the arms which connect the hub to the circumference are formed of agglomerated fibers which are parallel to each other and which absorb the collision energy by being progressively deformed, so that wounds which could possibly affect the driver , is greatly reduced.
I styrerattet som er beskrevet i det sistnevnte patent, er imidlertid bindemidlet som impregnerer fibrene for at disse skal agglomerere, en harpiks av den varmtherdnende type, slik at fibrene må innarbeides i bindemidlet ved en polymerisasjonsbehandlingsprosess under trykk og ved høy temperatur beregnet å skulle herde harpiksen hvori fibrene først er blitt impregnert ved neddykking. In the steering wheel described in the latter patent, however, the binder that impregnates the fibers in order for them to agglomerate is a resin of the thermosetting type, so that the fibers must be incorporated into the binder by a polymerization treatment process under pressure and at a high temperature intended to harden the resin in which the fibers have first been impregnated by immersion.
En slik prosess byr i praksis på en rekke ulemper:In practice, such a process offers a number of disadvantages:
- Den flytende harpiks flyter meget lett langs trådene med mindre de først impregnerte tråder lagres i et kaldt rom, hvilket er komplisert og kostbart. - På denne måte beskadiges materialet og maskiner og gjør vedlikeholdet vanskelig. - Harpiksen flyter inn i alle formskjøter og må fjernes fra formen, hvilket innebærer en meget kostbar rengjøring av delene. - Et stort antall former er nødvendige for denne prosess for at den skal kunne utnyttes for industriell masseproduksjon. - Det er nødvendig i hvert trinn å belegge formene med et slippmiddel for formen eller å plassere varmformede ark i formene. - Det er nødvendig omhyggelig å rense formene mellom hver formningsoperasjon for det store antall rester som be-finner seg i alle skjøteplan. - The liquid resin flows very easily along the threads unless the first impregnated threads are stored in a cold room, which is complicated and expensive. - In this way, the material and machines are damaged and maintenance is difficult. - The resin flows into all mold joints and must be removed from the mold, which involves a very expensive cleaning of the parts. - A large number of molds are necessary for this process so that it can be used for industrial mass production. - It is necessary in each step to coat the molds with a release agent for the mold or to place hot-formed sheets in the molds. - It is necessary to carefully clean the molds between each molding operation for the large number of residues that are found in all joint planes.
- De produserte deler er ujevne og med tvilsom geometri.- The manufactured parts are uneven and of questionable geometry.
- Produksjonssyklusen er lang og kostbar.- The production cycle is long and expensive.
- Polymerisasjonstiden begrenser produksjonskapasiteten.- The polymerization time limits the production capacity.
- De nødvendige investeringer er meget store for å kunne opp-nå industrielle produksjonskapasiteter som er forenlige med bilindustriens krav. - The necessary investments are very large to be able to achieve industrial production capacities that are compatible with the requirements of the car industry.
Ved den foreliggende oppfinnelse overvinnes alleWith the present invention, all are overcome
disse ulemper.these disadvantages.
Ved fremgangsmåten ifølge oppfinnelsen for fremstilling av sammensatte gjenstander som omfatter fibre som er agglomerert med en syntetisk harpiks, anvendes en harpiks av den termoplastiske type, og denne harpiks blir først påført på de enkelte fibre, hvorefter disse fibre sammen-føyes til en bunt ved smelting i harpiksen, og bunten vikles opp i formen, mens det sammensatte materiale efterlates slik at det tiltagende avkjøles i formen, hvorefter den erholdte gjenstand fjernes. Påføringen av harpiksen på enkeltfibre kan utføres på flere forskjellige måter. In the method according to the invention for the production of composite objects comprising fibers that are agglomerated with a synthetic resin, a resin of the thermoplastic type is used, and this resin is first applied to the individual fibers, after which these fibers are joined into a bundle by melting in the resin, and the bundle is wound up in the mold, while the composite material is left so that it gradually cools in the mold, after which the resulting object is removed. The application of the resin to individual fibers can be carried out in several different ways.
Ved den første måte blir kontinuerlige fibre først oppvarmet og derefter belagt med harpiksen f.eks. ved at de ledes inn i et fluidisert bad av harpikspulver, eller ved at de omhylles ved ekstrudering av smeltet harpiks, eller ved at harpikspulver blir elektrostatisk avsatt. In the first method, continuous fibers are first heated and then coated with the resin, e.g. by being led into a fluidized bath of resin powder, or by being enveloped by extrusion of molten resin, or by resin powder being electrostatically deposited.
Ifølge denne utførelsesform kan fibrene sammenføyes direkte ved forhøyet temperatur i bunter og derefter vikles i formen, hvori de agglomereres til hverandre under av-kjøling. According to this embodiment, the fibers can be joined directly at an elevated temperature into bundles and then wound into the mold, in which they are agglomerated to each other during cooling.
Ifølge en annen utførelsesform belegges kontinuerlige fibré med harpiks ved lav temperatur, f.eks. ved at fibrene innføres i en oppløsning eller ved vandig påsprutning av harpiksen eller ved anvendelse av et klebemiddel. Når fibrene derefter oppvarmes, vil oppløsningsmidlet bli fjernet eller klebemidlet bli reaktivert før eller under sammenføyningen av fibrene. According to another embodiment, continuous fibers are coated with resin at a low temperature, e.g. by introducing the fibers into a solution or by aqueous spraying of the resin or by using an adhesive. When the fibers are then heated, the solvent will be removed or the adhesive will be reactivated before or during joining of the fibers.
Ifølge de to utførelsesformer er det, selv om produktet fås direkte straks formen er blitt avkjølt og kan anvendes i denne tilstand, mulig dersom det er ønsket med en forbedret sammenpressing av fibrene mot hverandre og på navet i tilfellet av et styreratt, å herde det tidligere erholdte nettverk i en saramenpresningsform ved forhøyet temperatur. Derved fås et sluttprodukt med meget presise dimensjoner According to the two embodiments, although the product is obtained directly as soon as the mold has cooled and can be used in this state, it is possible, if desired, with an improved compression of the fibers against each other and on the hub in the case of a steering wheel, to harden it earlier obtained networks in a saramen pressing form at elevated temperature. This results in a final product with very precise dimensions
og uten noen deformasjon. Ved en slik metode er det mulig å herde metalliske innsatsstykker og plastinnsatsstykker i produktet dersom dette skulle være nødvendig, f.eks. for å forsterke armene i forhold til rattomkretsen eller for å innarbeide nødvendige deler for elektriske innretninger eller andre. and without any deformation. With such a method, it is possible to harden metallic inserts and plastic inserts in the product should this be necessary, e.g. to reinforce the arms in relation to the steering wheel circumference or to incorporate necessary parts for electrical devices or others.
Som fibre kan naturlige eller syntetiske fibre, mineralfibre eller organiske fibre, som fibre av polyamider, polyethylen, polypropylen, polyacrylharpikser, eller fibre av bomull, bor, carbon, glass eller metall, som aluminium eller stål, eller også blandinger av fibre av forskjellig art anvendes. Det er også av interesse å anvende fibre som på den ene side omfatter et belegg med en første harpiks påført ved elektrostatisk avsetning av harpikspulver på fibrene, og som på den annen side har en omhyIling av en annen termoplastisk harpiks som kan være den samme eller forskjellig og som fås ved ekstrudering av denne, i henhold til fransk patent 8310632 av 28. juni 1983. Som termoplastisk harpiks kan polyamider, polyethylener, polypropylener, polystyrener eller slike modifiserte harpikser eller lignende harpikser anvendes. As fibers, natural or synthetic fibers, mineral fibers or organic fibers, such as fibers of polyamides, polyethylene, polypropylene, polyacrylic resins, or fibers of cotton, boron, carbon, glass or metal, such as aluminum or steel, or also mixtures of fibers of different types are used. It is also of interest to use fibers which on the one hand comprise a coating with a first resin applied by electrostatic deposition of resin powder on the fibres, and which on the other hand have a coating of another thermoplastic resin which may be the same or different and which is obtained by extruding this, according to French patent 8310632 of 28 June 1983. As thermoplastic resin, polyamides, polyethylenes, polypropylenes, polystyrenes or such modified resins or similar resins can be used.
Fordelen ved dsn foreliggende fremgangsmåte sammen-lignet med de kjente fremgangsmåter, og spesielt den fremgangsmåte som er beskrevet i fransk patent 7905080,er å muliggjøre en produksjon som bare krever en enkelt filament-viklingsform og eventuelt en sammenpresningsform for å opp- The advantage of the present method compared to the known methods, and in particular the method described in French patent 7905080, is to enable a production that only requires a single filament winding form and possibly a compression form in order to
nå en bedre overflatetilstand eller for at delen skal få en spesiell form. Dessuten kan begge former eventuelt være forbundet med hverandre og sammenpresningen fås ved stengning av formen. I tillegg vil delene komme ut fra formene uten grader, og det er ikke behov for å anvende et slippmiddel for formen, og de produserte deler er gode uten noen finishing-behandling. to achieve a better surface condition or to give the part a special shape. In addition, both molds can optionally be connected to each other and the compression is achieved by closing the mold. In addition, the parts will come out of the molds without burrs, and there is no need to use a release agent for the mold, and the produced parts are good without any finishing treatment.
I de nedenstående eksempler er utførelsen av den foreliggende fremgangsmåte beskrevet i forbindelse med fremstilling av styreratt for biler og under henvisning til den ledsagende tegning, i form av to utførelsesformer. De på tegningen viste to figurer gjengir skjematisk trinnrekke-følgen for den foreliggende fremgangsmåte. In the examples below, the implementation of the present method is described in connection with the production of steering wheels for cars and with reference to the accompanying drawing, in the form of two embodiments. The two figures shown in the drawing schematically represent the sequence of steps for the present method.
Eksempel 1Example 1
På Fig. 1 er skjematisk vist spoler 1 hvorfra de enkelte fibre 2 vikles av for agglomerering for å utgjøre gjenstandens rammeverk. Disse fibre kan eventuelt forvarmes av en HT-spole 3, og de neddykkes derefter i et bad 4 som inneholder pulverformig harpiks som holdes i fluidisert tilstand ved hjelp av en luftblest 5. Partiklene hefter til fibrene 2 som føres gjennom harpiksvolumet 4, på grunn av elektrostatisk tiltrekning. Ved utløpet passerer fibrene gjennom en annen oppvarmingssone 5 hvori partiklene smelter under innvirkning av varme og danner et bindemiddel som agglomerer fibrene til en fleksibel, enhetlig bunt 6 Fig. 1 schematically shows spools 1 from which the individual fibers 2 are unwound for agglomeration to form the object's framework. These fibers can optionally be preheated by an HT coil 3, and they are then immersed in a bath 4 containing powdery resin which is kept in a fluidized state by means of an air blast 5. The particles adhere to the fibers 2 which are passed through the resin volume 4, due to electrostatic attraction. At the outlet, the fibers pass through another heating zone 5 in which the particles melt under the influence of heat and form a binder that agglomerates the fibers into a flexible, uniform bundle 6
som efter å ha passert gjennom en utligningstrekkeplate 7, plasseres i en form 9 ved hjelp av en robot 8, og i formen avkjøles fibrene mens de får den sluttelige form. which, after passing through an equalizing drawing plate 7, is placed in a mold 9 with the help of a robot 8, and in the mold the fibers cool while they take their final shape.
Ved praktiseringen av dette eksempel er fibrene 1 glassfibre som har betegnelsen "Roving R 28 of 320 tex". In the practice of this example, the fibers 1 are glass fibers which have the designation "Roving R 28 of 320 tex".
De har en diameter av ca. 10 og passerer gjennom badet med en hastighet som eventuelt kan nå opp til 100 m/min. Harpiksen er av polyamidtypen, og oppspolingsenhetene 3 og 5 har en temperatur av 220°C. They have a diameter of approx. 10 and passes through the bath at a speed that can possibly reach up to 100 m/min. The resin is of the polyamide type, and the winding units 3 and 5 have a temperature of 220°C.
Eksempel 2Example 2
Det fremgår av Fig. 2 at ifølge den annen utførelses-form av den foreliggende fremgangsmåte overføres bunten som forlater badet, til en ekstruder 10 som den forlater omhyllet med et belegg av termoplastisk harpiks som kan være den samme harpiks som i badet 4 eller en annen harpiks. Derfra blir den omhyllede tråd trukket av en innretning 11 gjennom en kjølesone 12 og til slutt lagret i en spole 13. Denne mellomlagring er nødvendig på grunn av den kjensgjern-ing at den behandlede tråd 4-10 kommer fra en forgarnsspole 1' og krysser hele systemet med en hastighet av ca. 1000 m/min. Derefter avrulles omhyllet tråd fra flere spoler 13a, 13b, 13c osv. og sammenføres til en bunt 14 og oppvarmes igjen i 15, slik at ved fornyet oppvarming vil harpikspar-tiklene som er dekket av omhyllingen, smelte og sammen med omhyIlingen dannet bindemidlet som agglomererer fibrene. Denne bunt legges ned og fordeles ved hjelp av et robothode 8' i formen 9' i hvilken den avkjøles mens den får sin endelige form, som i eksempel 1. Ved til slutt å stenge formen 9 (eller 9') under trykk blir gjenstandens overflatetilstand forbedret eller dens form forandret. For eksempel blir små søkk dannet langs styrerattets omkrets og forbedrer grepet. Montasjen i formen kan også dannes uten oppvarming idet formen oppvarmes senere. Oppvarmingen kan utføres ved hjelp av infrarøde stråler, med en ikke-oxyderende flamme, med laser eller med et hvilket som helst annet middel. It is clear from Fig. 2 that according to the second embodiment of the present method, the bundle leaving the bath is transferred to an extruder 10 which leaves it coated with a coating of thermoplastic resin which can be the same resin as in the bath 4 or another resin. From there, the sheathed thread is pulled by a device 11 through a cooling zone 12 and finally stored in a spool 13. This intermediate storage is necessary due to the fact that the treated thread 4-10 comes from a pre-yarn spool 1' and crosses the entire the system at a speed of approx. 1000 m/min. Then coated wire is unwound from several coils 13a, 13b, 13c, etc. and brought together into a bundle 14 and heated again in 15, so that upon renewed heating the resin particles covered by the coating will melt and together with the coating form the binder that agglomerates the fibers. This bundle is laid down and distributed by means of a robot head 8' into the mold 9' in which it cools while it takes its final shape, as in example 1. By finally closing the mold 9 (or 9') under pressure, the surface condition of the object becomes improved or its form changed. For example, small depressions are formed along the circumference of the steering wheel and improve grip. The assembly in the mold can also be formed without heating, as the mold is heated later. The heating can be carried out by means of infrared rays, with a non-oxidizing flame, with a laser or by any other means.
Formen anvendt i dette eksempel fører til dannelseThe form used in this example leads to formation
av styreratt hvis særtrekk er spesielt verdifulle, som angitt i beskrivelsens innledning,omen metodene ifølge oppfinnelsen kan generelt anvendes for sammensatte gjenstander med filamentoppvikling som for tiden erholdt fra varmtherdnende harpikser, og nærmere bestemt slike som ikke kan rulles opp på en spindel. Som eksempler kan nevnes innen bilindustrien, torsjonsstenger, propellaksler, opphengningsinnretninger, of a steering wheel whose distinctive features are particularly valuable, as indicated in the introduction of the description, although the methods according to the invention can generally be used for composite objects with filament winding currently obtained from heat-setting resins, and more specifically those that cannot be rolled up on a spindle. As examples can be mentioned in the automotive industry, torsion bars, propeller shafts, suspension devices,
