Definitions

  • the present invention relates to an impact-absorbing member, protective clothing including the impact-absorbing member, and a process for producing an impact-absorbing member.
  • Patent Document 1 proposes a fiber-reinforced resin molded product as an impact-absorbing plate, and the fiber-reinforced resin molded product is formed by impregnating a fabric, which contains 0.01% by weight to 10% by weight of a fluorine compound, with a resin composition.
  • Patent Document 1 JP 2002-316319 A
  • a principal object of the present invention is to provide an impact-absorbing member having excellent blade-proof performance.
  • An impact-absorbing member according to the present invention includes a plurality of stretched resin films stacked and bonded to one another.
  • the plurality of stretched resin films include a biaxially stretched resin film.
  • the plurality of stretched resin films include the biaxially stretched resin film and a uniaxially stretched resin film.
  • At least one of principal surfaces of a laminate of the plurality of stretched resin films may be formed of a uniaxially stretched resin film.
  • the plurality of stretched resin films include a plurality of uniaxially stretched resin films whose stretching directions are mutually different.
  • the impact-absorbing member according to the present invention may further include at least one of a woven fabric and a braided fabric which is stacked on the plurality of stretched resin films.
  • the plurality of stretched resin films include a plurality of biaxially stretched resin films whose stretching directions are mutually inclined.
  • the stretched resin film includes a crystalline polymer.
  • a 180° peeling strength per 1 cm of width of the adjacent stretched resin films is preferably 0.1 kgf to 3 kgf.
  • the adjacent stretched resin films may be bonded directly to each other.
  • the impact-absorbing member according to the present invention may further include an adhesive layer which bonds adjacent stretched resin films to each other.
  • the adjacent stretched resin films may be at least partially kept from being not bonded to each other.
  • the stretched resin films may have a through-hole, and the plurality of stretched resin films may be bound together by a binding member inserted in the through-hole.
  • a binding member is formed of a metal.
  • the stretched resin film may be formed of a porous material.
  • the stretched resin film may have a vent hole.
  • the vent hole provided in one of the stretched resin films and a vent hole provided in a stretched resin film adjacent to the one of the stretched resin films do not overlap each other.
  • Protective clothing according to the present invention includes the impact-absorbing member according to the present invention.
  • a plurality of stretched resin films including a biaxially stretched resin film are stacked and thermocompression-bonded to obtain an impact-absorbing member.
