Abstract

The invention concerns a method of forming preforms to manufacture fibre composites, comprising monoaxial or biaxial laid-yarn fabrics, which are injected with a thermosetting plastic or a thermoplastic material or - if the fabric is made from a thermoplastic hybrid yarn - are heated. According to the novel method, the fabric material is applied on a core (5), which is an elongate body, in the form of ribbons (1, 2, 3, 4). These are advanced at an angle relative to the core (5) and are wound onto the latter in overlapping relationship, preferably by rotation of the core (5) about the longitudinal centre core axis while said core is simultaneously being advanced in its longitudinal direction.

Description

lO l5 20 25 30 35 511 108 2 tvärgående eller längsgående. Genom att mata fram flera banor av sådana monoaxiella trådlagsdukar med i inbördes olika vinklar sig sträckande väfttrådar, den ena banan över den andra, kan man skapa en flerskiktsbana, som efter kapning i tvärled bildar en flerskiktsduk. Denna kan sedan ingå i en genom formpressning tillverkad fiber- komposit av plast. Förutom god dragstyrka i alla rikt- ningar har denna flerskiktsduk fördelen framför ovan- nämnda multiaxiella trådlagsduk att ha mycket god draper- barhet, vilket innebär, att den är väl formbar även vid gjutformar med förhållandevis kraftigt utskjutande partier utan risk för att spricka sönder eller vika sig. 10 l5 20 25 30 35 511 108 2 transverse or longitudinal. By feeding several webs of such monoaxial filament webs with weft threads extending at mutually different angles, one web over the other, one can create a multilayer web, which after cutting transversely forms a multilayer fabric. This can then be included in a fiber composite made of compression molding. In addition to good tensile strength in all directions, this multilayer fabric has the advantage over the above-mentioned multiaxial wire mesh fabric to have very good drapeability, which means that it is well malleable even in molds with relatively strongly protruding portions without risk of cracking or folding sig.

Genom uppfinningen har tillkommit en ny metod, som utgör en vidareutveckling av ovan beskrivna metod och uppvisar ytterligare fördelar framför denna. Det som utmärker den nya metoden är, att dukmaterialet appliceras på en kärna, som utgör en långsträckt kropp, i form av remsor, vilka frammatas i vinkel relativt kärnan och varandra och lindas på denna omlott genom vridning av kärnan kring dennas längdmittaxel och samtidig fram- matning av densamma i längdriktningen.Through the invention, a new method has been added, which constitutes a further development of the method described above and has further advantages over this. What distinguishes the new method is that the cloth material is applied to a core, which forms an elongate body, in the form of strips, which are advanced at an angle relative to the core and each other and wound on it by rotating the core about its longitudinal center axis and at the same time feeding it in the longitudinal direction.

Uppfinningen skall i det följande närmare beskrivas med hänvisning till de bifogade ritningarna, på vilka fig 1 visar perspektiviskt en kärna, med påbörjad pålindning av fyra remsor, fig 2 visar den struktur som bildas efter färdig lindning, fig 3 visar en variant av pålindningen i fig 1, fig 4 visar strukturen vid färdig- lindad kärna enligt fig 3 samt fig 5-7 visar ett antal trådlagsdukar med inbördes olika strukturer.The invention will be described in more detail below with reference to the accompanying drawings, in which Fig. 1 shows in perspective a core, with commenced winding of four strips, Fig. 2 shows the structure formed after finished winding, Fig. 3 shows a variant of the winding in Figs. 1, Fig. 4 shows the structure of a pre-wound core according to Fig. 3 and Figs. 5-7 show a number of wire cloths with mutually different structures.

I fig l visas ett utförande där fyra remsor l,2,3 och 4 av monoaxiella trådlagsdukar lindas på en kärna 5. Remsorna l,2,3,4 visas för åskådlighets skull något schematiskt, dvs det enda som åskàdliggjorts är sträckningen av deras trådar 6,7,8, resp 9. Sålunda sträcker sig trådarna 6 i remsan l snett relativt remsans l frammatningsriktning, trådarna 7 i remsan 2 likaledes snett relativt denna remsas 2 fram-matningsriktning och 10 15 20 25 30 35 511 108 3 trådarna 8 och 9 i remsorna 3 resp 4 vinkelrätt mot dessa remsors 8 resp 9 frammatningsriktning.Fig. 1 shows an embodiment where four strips 1, 2,3 and 4 of monoaxial wire cloths are wound on a core 5. The strips 1, 2,3,4 are shown for the sake of illustration somewhat schematically, i.e. the only thing illustrated is the stretching of their wires 6,7,8, respectively 9. Thus, the threads 6 in the strip 1 extend obliquely relative to the feed direction of the strip 1, the threads 7 in the strip 2 likewise obliquely relative to the feed direction of this strip 2 and the threads 8 and 9 in strips 3 and 4, respectively, perpendicular to the feed direction of these strips 8 and 9, respectively.

Kärnan 5 visas på ritningen såsom en långsträckt parallellepipedisk kropp med rektangulärt tvärsnitt men kan givetvis även ha andra former, t ex vara rund eller kvadratisk i tvärsnitt. Kärnan 5 består lämpligen av cellplast men kan även vara tillverkad i trä eller metall, t ex aluminium. Kärnan 5 antages vara vridbar kring sin längdmittaxel i pilens 10 riktning och även vara förskjutbar i sin längdriktning uppåt (eller inåt) i figuren.The core 5 is shown in the drawing as an elongated parallelepiped body with a rectangular cross-section, but can of course also have other shapes, for example be round or square in cross-section. The core 5 suitably consists of cellular plastic but can also be made of wood or metal, eg aluminum. The core 5 is assumed to be rotatable about its longitudinal center axis in the direction of the arrow 10 and also to be displaceable in its longitudinal direction upwards (or inwards) in the figure.

När remsorna 1,2,3,4 lindas på kärnan 5 på det sätt som framgår av fig 1 och i nämnd ordning, kommer de att på kärnan bilda en flerskiktsduk med den struktur som visas i fig 2. Sålunda kommer trådarna 6 i remsan l att lägga sig närmast kärnan 5 i dennas tvärriktning, trådarna 7 i remsan 2 att lägga sig på trådarna 6 i kärnans 5 längdriktning, trådarna 8 i remsan 3 att lägga sig på trådarna 7 i snedvinkel över dessa samt trådarna 9 i remsan 4 att lägga sig på trådarna 8 i huvudsak vinkel- rätt mot dessas riktning. Genom detta lindningssätt erhåller man en flerskiktsduk med såväl god dragstyrka i alla riktningar som god draperbarhet.When the strips 1,2,3,4 are wound on the core 5 in the manner shown in Fig. 1 and in said order, they will form on the core a multilayer fabric having the structure shown in Fig. 2. Thus, the threads 6 in the strip 1 to lie closest to the core 5 in its transverse direction, the wires 7 in the strip 2 to lie on the wires 6 in the longitudinal direction of the core 5, the wires 8 in the strip 3 to lie on the wires 7 at an oblique angle above them and the wires 9 in the strip 4 to lie on the wires 8 substantially perpendicular to their direction. Through this winding method, a multilayer fabric is obtained with both good tensile strength in all directions and good drapeability.

I fig 3 visas ett utförande som endast skiljer sig från utförandet i fig 1 i det avseendet, att remsorna 1 och 4 har bytt plats samt att remsan 2 och 3 påmatas kärnan 5 före remsorna 1 och 4. Denna lilla förändring ger den annorlunda struktur hos den bildade flerskikts- duken, som framgår av fig 4. Sålunda kommer i detta fall trådarna 7 i remsan 2 att befinna sig närmast kärnan 5 och sträcka sig i kärnans längdled, trådarna 8 i remsan 3 att ligga tvärs över trådarna 7 i remsan 2, trådarna 9 i remsan 4 att ligga vinkelrätt tvärs över trådarna 8 i remsan 3 samt trådarna 6 i remsan 1 att ligga över tråd- arna 9 i remsan 4 vinkelrätt mot kärnans längdriktning.Fig. 3 shows an embodiment which differs only from the embodiment in Fig. 1 in that strips 1 and 4 have changed places and that strips 2 and 3 are fed to the core 5 before strips 1 and 4. This small change gives the different structure of the formed multilayer fabric, as shown in Fig. 4. Thus, in this case, the wires 7 in the strip 2 will be closest to the core 5 and extend in the longitudinal direction of the core, the wires 8 in the strip 3 will lie across the wires 7 in the strip 2, the wires 9 in the strip 4 to lie perpendicularly across the wires 8 in the strip 3 and the wires 6 in the strip 1 to lie over the wires 9 in the strip 4 perpendicular to the longitudinal direction of the core.

Med mycket enkla medel kan man med metoden enligt uppfinningen ändra den på kärnan 5 bildade fler- 'l '12 Éšff-'í 2-15 11:22 LÉ: “~.PE.I"“~.K.FG“~.ÄNSKPZÉ?H25?_D01" 511108 10 15 20 25 30 4 skiktsdukens såväl struktur som tjocklek. Detta kan således göras genom att ändra bredden på remsorna l,2,3,4, genom att ändra tråddensiteten i tyget, genom att ändra hastigheten på kärnans frammatning i sin längdled, genom att ändra kärnans 5 vridningshastighet eller genom att ändra remsornas l,2,3,4 inmatningsvinkel relativt kärnan 5. Givetvis kan man även ändra antalet remsor, som samtidigt matas på kärnan 5. Vid användning av biaxiella trådlagsdukar kan man uppnå samma fler- skiktsstruktur med färre antal remsor.With very simple means it is possible with the method according to the invention to change the multiple formed on the core 5 '1 '12 Éšff-'í 2-15 11:22 LÉ: “~ .PE.I" “~ .K.FG“ ~. ÄNSKPZÉ? H25? _D01 "511108 10 15 20 25 30 4 both the structure and the thickness of the layer cloth. This can thus be done by changing the width of the strips 1, 2,3,4, by changing the thread density in the fabric, by changing the speed of the feed of the core in its longitudinal direction, by changing the rotational speed of the core 5 or by changing the strips 1, 2 , 3,4 feed angle relative to the core 5. Of course, you can also change the number of strips, which are fed to the core 5 at the same time. When using biaxial wire cloths, you can achieve the same multilayer structure with fewer strips.

En fördel med metoden enligt uppfinningen gentemot ovan beskrivna metod enligt SE 9700893-2, där tygbanor matas fram i samma riktning och lägges på varandra för att bilda en flerskiktsduk är, att material- spillet blir mindre och att rovingtrådarna inte löper i hela kärnans 5 riktning utan endast är så långa som remsornas bredd. Detta ökar draperbarheten utan någon reducering av dragstyrkan i flerskiktsduken. Lämpligt är dock att linda remsorna något omlott för att beakta fibermaterialets mekaniska egenskaper.An advantage of the method according to the invention compared to the method described above according to SE 9700893-2, where fabric webs are fed in the same direction and laid on top of each other to form a multilayer cloth, is that the material waste becomes smaller and that the roving threads do not run in the whole core direction. but are only as long as the width of the strips. This increases the drapeability without any reduction in the tensile strength of the multilayer fabric. It is suitable, however, to wrap the strips slightly wrapped to take into account the mechanical properties of the fibrous material.

I fig 5,6 och 7 visas slutligen exempel på hur man genom kombination av tràdlagsdukar med olika struktur kan erhålla en flerskiktsduk av samma karaktär. Genom att sålunda anbringa duken i fig 5b mellan dukarna i fig 5a och c, duken i fig 6b mellan dukarna i fig 6a och c samt duken i 7b mellan dukarna i fig 7a och c erhålles fler- skiktsdukar med samma struktur.Finally, Figures 5, 6 and 7 show examples of how a multilayer cloth of the same character can be obtained by combining wire cloths with different structures. Thus, by placing the cloth in Fig. 5b between the cloths in Figs. 5a and c, the cloth in Fig. 6b between the cloths in Figs. 6a and c and the cloth in 7b between the cloths in Figs. 7a and c, multilayer cloths with the same structure are obtained.
