Abstract

The invention relates to a method for the manufacture of a recyclable product material in order to achieve a predetermined strength within a predetermined strain rate interval. The product material comprises at least one matrix material and at least one fibre material. The matrix and fibre materials are chosen so that the values of their moduli of elasticity (Eij), moduli in shear (Gij) and the Poisson's ratios ( upsilon ij) assume a discontinuous distribution of the said matrix and fibre material quantities within different volume elements of the product material. It is further intended that a display curve defining a continuous distribution of a fibre size of the product material should exhibit symmetry in different volume elements of the product material.

Description

504 882 10 15 20 25 30 35 siktkurva. 504 882 10 15 20 25 30 35 sieve curve.

Enligt ett annat särskilt kännetecken för uppfinningen uppvisar fiberrnaterialets/de blandade fibermaterialens formfaktor, dvs förhållandet tiberlängd-/fiberdiameten spridning varigenom uppnås att ett flertal fibrer kan fås att överbrygga de öar av inhomogeniteter, som annars skulle ge upphov till bristfällig vidhäftning mellan fibrerna.According to another particular feature of the invention, the form factor of the fi bearing material / the mixed fi bearing materials, i.e. the ratio tiberlength- / erdberdiameter, has a distribution whereby it is achieved that a number of fibers can be made to bridge the islands of inhomogeneities which would otherwise give rise to defective adhesion.

Företrädesvis är som framgår av ytterligare ett särskilt kännetecken för uppfinningen närrmda fördelningar så stora att det faktum ett eller flera av matris-/fibermaterialen är kontaminerade ej inverkar menligt på produktmaterialets hâllfasthet.Preferably, as is apparent from a further particular feature of the invention, the distributions approached are so large that the fact that one or more of the matrix / carrier materials are contaminated does not adversely affect the strength of the product material.

Enligt ytterligare kännetecken för uppfinningen är nämnda fiberrnaterials resp. forrnfaktorer sådana, att kontarnineringarnas partikelstorlek överskrids, dvs att det faktum ett eller flera av matris-/ñberrnaterialen är kontarninerade, ej inverkar menligt på produktmaterialets hållfasthet.According to further features of the invention, said aterial berrnaterials resp. factors such that the particle size of the contaminants is exceeded, i.e. the fact that one or more of the matrix / ñber materials are contaminated, do not adversely affect the strength of the product material.

Ytterligare fördelar hos uppfinningen kommer att framgå av följande beskrivning av denna med hänvisning till ritningen på vilken fig 1 är ett exempel på en siktkurva vid den uppfinningssenliga metoden. Fig 2 illustrerar olika volymselement i ett produkt- material.Further advantages of the invention will become apparent from the following description thereof with reference to the drawing, in which fi g 1 is an example of a visibility curve in the inventive method. Fig. 2 illustrates different volume elements in a product material.

Vid framställning av ett återvinningsbart produktmaterial enligt den uppfinnings- enliga metoden sker denna medelst för fackmannen välkänd utrustning av konven- tionellt slag kompletterad med mätanordningar för kontroll av matris- och fibennate- rialens elasticitets- och skjuvmoduler samt ur dessa värden framräknade tvärkontrak- tionstal. Skulle den diskontinuerliga fördelningen av ovannämnda storheter ej upp- nås, som är utmärkande för uppfinningen, utföres en manuell eller automatisk korri- gering, varpå just det material hos vilket storheterna ej fått diskontinuerliga fördel- ningen återkopplas i processen, dvs materialet genomlöper processen ännu en gång.When producing a recyclable product material according to the inventive method, this is done by means of conventional equipment well known to those skilled in the art, supplemented with measuring devices for checking the elasticity and shear modules of the matrix and bone material and cross-contraction numbers calculated from these values. If the discontinuous distribution of the above-mentioned quantities is not achieved, which is characteristic of the invention, a manual or automatic correction is performed, whereupon the material with which the quantities have not received the discontinuous distribution is fed back into the process, ie the material undergoes another process. walk.

Vad beträffar siktkurvan, som definierar produktmaterialets tiberstorlek, hänvisas som exempel till tig 1. I denna siktkurva förutsättes att ett aglomerat /granulat har diametermaxima på 4 mm. Huvuddelen av fibrema har här valts till längder runt 2 mm med en spridning enligt kurvan. 3 504 882 Fig 2 avser att illustrera ett prov 1 av ett återvinningsbart produktmaterial framställt enligt den uppfinníngsenliga metoden. Aglomerat/granulat har sammanfogats som volymselement lal , la2 med olika fóreträdesriktningar hos fibrema, vilka är inba- kade i de olika volymselementen. För varje sådant volymselement skall alltså enligt uppfinningen gälla, att värdena på elasticitetsmodulen, skjuvmodulen och tvärkon- traktionstalet skall skilja sig från motsvarande storheters värden för intilligande volymselement.With regard to the sieve curve, which defines the tiber size of the product material, reference is made as an example to Fig. 1. In this sieve curve it is assumed that an agglomerate / granulate has a diameter maximum of 4 mm. The main part of the fi brema has here been chosen to lengths around 2 mm with a spread according to the curve. Fig. 2 is intended to illustrate a sample 1 of a recyclable product material prepared according to the inventive method. Aglomerates / granules have been joined together as volume elements la1, la2 with different preference directions of fi brema, which are embedded in the different volume elements. Thus, for each such volume element, according to the invention, the values of the modulus of elasticity, the shear modulus and the transverse contraction number must differ from the values of corresponding quantities for adjacent volume elements.
