Definitions
- the present invention relates to combinations of polyolefin filaments and yarns having high tensile strengths and moduli and low wetting and adhesive power, in particular in respect of customary matrix materials, and filaments and yarns of high wetting and adhesive power.
- Polyolefin filaments and yarns having high tensile strengths and high moduli have very poor wettability by and adhesion to hydrophilic materials, such as heat-curing phenolic, epoxy, vinylester, polyester and acrylate resin based resins customarily used for producing composite materials, and also thermoplastics and rubber. For this reason they are not particularly suitable for producing composite materials without pretreatment.
- hydrophilic materials such as heat-curing phenolic, epoxy, vinylester, polyester and acrylate resin based resins customarily used for producing composite materials, and also thermoplastics and rubber. For this reason they are not particularly suitable for producing composite materials without pretreatment.
- the polyolefin filaments and yarns of low wetting and adhesive power are those which have been produced by the gel process and subsequent high drawing.
- This gel process which is described for example in DE Offenlegungsschrift 3,724,434 and also in GB-A-2,042,414 and -2,051,667, comprises essentially dissolving a polyolefin in a solvent, moulding the solution at a temperature above the dissolving temperature of the polyolefin into a filament, cooling the filament, for gelling, to a temperature below the dissolving temperature and then drawing the gel filament with solvent removal, preferivelyably employing draw ratios of more than 20, in particular more than 30.
- the polyolefins used consist preferably of polyethylenes in particular linear polyethylenes, having an ultrahigh molecular weight of more than 600,000 g/mol (weight average of molecular weight). These polyethylenes may contain minor amounts preferably not more 5 mol %, of one or more other alkenes copolymerizable therewith, such as propylene, butylene, pentene, hexene, 4-methylpentene, octene etc.
- the polyethylenes can have from 1 to 10, in particular 2 to 6, methyl or ethyl groups per 1,000 carbon atoms.
- polystyrene resins for example polypropylene homopolymers and copolymers; furthermore, the polyolefins used may contain minor amounts of one or more other polymers in particular alkene-l-polymers.
- polyolefin filaments having tensile strengths of more than 2 GPa and moduli of more than 60 GPa.
- the filaments and yarns of high wetting and adhesive power consist preferably of glass, carbon, polyamides or polyesters. However, it is also possible to resort to other filaments and yarns of high wetting and adhesive power in respect of the abovementioned materials.
- the two filament and yarn types are combined by core spinning a filament or yarn of low wetting and adhesive power with a filament and/or a yarn of high wetting and adhesive power, or by twisting the two components.
- the proportion of filaments or yarns of high wetting and adhesive power in relation to the proportion of filaments and yarns of low wetting and adhesive power is 10 to 50% by weight, in particular 15 to 30% by weight, particularly advantageously these proportions being about 25% by weight in the case of core spinning and about 15% by weight in the case of twisting.
- Composite materials which have been produced using combinations according to the invention as reinforcing materials can be used for example to produce sport articles such as tennis rackets or golf clubs, boat hulls such as kayak or canoe boat hulls, antiballistic articles, helmets, high-pressure hoses etc.
