Definitions

  • the present invention relates to a combination of filaments having substantially different damping re­sponses to mechanical vibrations in a matrix.
  • filaments having substantially different damping responses to mechanical vibrations preferably filaments having high internal damping and consisting of highly drawn filaments of polymers having ultrahigh molecular weight and high tensile strengths and also moduli and filaments of low internal damping, for example glass fibers or carbon fibers, being embed­ded in a matrix made preferably of epoxy resin.
  • suitable materials for the matrix are unsaturated poly­ester, polyethylene, vinyl or thermoplastics.
  • the filaments of high internal damping have pre­ferably been produced by the gel process with subsequent drawing to high draw ratios.
  • the filaments of high internal damping consist of poly­mers having an ultrahigh molecular weight of more than 600,000 g/mol (weight average of molecular weight), in particular polyolefins.
  • the filaments of high internal damping are present in a proportion from 30 to 50% by volume of the total quantity of filaments in the composite material or combination.
  • a gel process whereby the filaments of high in­ternal damping are preferably produced is described for example in GB-A-2,042,414 and -2,051,667 and also in DE Offenlegungsschrift 3,724,434 and comprises essentially dissolving the particular polymer used for filament produc­tion in a solvent, molding the solution at a temperature above the dissolving temperature of the polymer into a filament, cooling the filament, for gelling, down to a temperature below the dissolving temperature and drawing the filament with solvent removal.
  • the polymer used for producing the filaments of high internal damping can be of any desired type, for example polyolefins, polyesters, polyamides, as also polyacrylonitrile, polyvinyl alcohol, polyvinyl chloride etc.
  • the filaments of high internal damp­ing consist of polymers of ultrahigh molecular weight, in particular polyolefins, particular preference being given to polyethylenes, in particular linear polyethy­lenes.
  • polyethylenes may contain minor amounts, preferably not more than 5 mol-%, of one or more other alkenes copolymerizable therewith, such as propylene, butylene, pentene, hexene, 4-methylpentene, octene etc. and have 1 to 10, in particular 2 to 6, methyl or ethyl groups per 1,000 carbon atoms.
  • other polyolefins for example polypropylene homo­polymers and copolymers.
  • the polyolefins used may also contain minor amounts of one or more other polymers, in particular alkene-1 polymers.
  • the filaments of high internal damp­ing have an oscillation damping factor of more than 20 . 10 ⁇ 3.
  • Filaments made of polyethylene of ultrahigh molecular weight have an internal damping factor of more than 100 . 10 ⁇ 3.
  • the filaments of high internal damping and of low internal damping are preferably embedded in a plastic matrix, made in particular of epoxy resin, polyester, polyethylene or the like.
  • the filaments of low internal damping are arranged around the filaments of high internal damping.
  • the combination of fibers of high internal damp­ing and fibers of low internal damping in a matrix improves the dynamic behavior of the composition as a consequence of the high damping capacity of the filaments, made for example of polyethylene of ultrahigh molecular weight, and as a consequence of the high energy absorption by the filament/­matrix interface, in particular if the filaments consist of a polyethylene of ultrahigh molecular weight and matrix of epoxy resin.
  • the composite materials made of filaments of high internal damping, filaments of low internal damping and a matrix in which the filaments are embedded are preferivelyably suitable for producing skis, hockey sticks, tennis rac­kets, arms for industrial robots, machine housings, angling rods, competition bows or the like.
  • the polyethylene filaments of ultrahigh molecular weight are preferably covered with glass fibers. In the event of oscillations this prevents the polyethylene fibers from emerging and projecting out of the matrix.
  • the composite article can be covered with a nonwoven to produce a smooth surface.
