Definitions

  • Shutters made of aluminum and steel are currently used to protect vulnerable portions of buildings and houses because shutters made from these materials can be manufactured to meet building and housing codes in regions which experience severe weather conditions.
  • steel and even aluminum shutters undergo pitting and strength degradation associated with corrosion, particularly in regions along the sea coast, where the air contains a high concentration of corrosive salt.
  • metal shutters can be somewhat heavy.
  • the present invention satisfies the current needs in the art by providing a panel precursor which can be used to produce an impact and puncture resistant panel, having a fiber reinforced polymeric matrix, which is relatively resistant to penetration, inexpensive, corrosion resistant and lightweight.
  • the impact and puncture resistant panels of the present invention are formed using a panel precursor comprising a plurality of laminae.
  • Each of the laminae comprises a plurality of strands, with each strand comprising a plurality of fibers, including reinforcing fibers, and at least one polymeric material.
  • the polymeric material forms all, substantially all, or at least part, of the matrix for the panel.
  • All of the matrix refers to the polymeric material from the strands providing all of the matrix except for that formed by any chemical treatment that may have been applied to the reinforcing fibers or any fiber made from the polymeric material.
  • Substantially all refers to the polymeric material from the strands being enough to provide a matrix for all of the reinforcing fibers of the panel.
  • Fig. 7 A presents a sectional view of the shutter shown in Fig. 7, taken along lines 7A-7A.
  • Fig. 8 presents a perspective view of a plurality of panels of this invention in the form of an additional alternate shutter.
  • the present invention is directed to an impact and puncture resistant panel 10.
  • the present panel 10 is a lamination comprising a plurality of laminae 12, each of which is formed from a plurality of reinforcement strands 16.
  • Each strand 16 includes a plurality of reinforcing fibers 17 and at least one polymeric material 19.
  • Useful reinforcing fibers can be any suitable reinforcing fiber including those selected from the group consisting of E-glass fibers, S-glass fibers, graphite fibers, aramid fibers, silicon carbide fibers, other fibers having suitable reinforcing characteristics and various combinations thereof.
  • the polymeric material 19 can be any suitable polymeric material including a thermoplastic polymeric material selected from the group consisting of polyamides, polypropylenes, polyesters, polyethylenes, polyphenylene sulfides and other like thermoplastic materials.
  • the polymeric material 19 may be in the form of polymeric fibers which are commingled or combined with one or more reinforcing fibers 17 to form the strands 16.
  • Methods for making commingled reinforcing and polymer fiber strands are disclosed in detail in copending U.S. Patent Application Serial No. 08/311,817 filed September 26, 1994 (Attorney Docket 23422A) and entitled “METHOD AND APPARATUS FOR FORMING COMPOSITE STRANDS," by Andrew B.

However, to insure the cohesiveness of the fibers, it is desirable for the chemical treatment to be applied to the fibers in a sufficient amount to also at least partially, if not fully, preimpregnate the resulting strand 16. As an alternative, the chemical treatment can be partially or fully impregnated into a formed strand 16.

Abstract

L'invention a trait à un panneau (10) léger, à l'épreuve du percement et de la corrosion et résistant aux impacts, façonné à l'aide d'un panneau précurseur comprenant plusieurs strates (12) dont chacune comporte plusieurs brins (16), chaque brin (16) étant constitué de plusieurs fibres, dont des fibres de renfort (17), et d'au moins un matériau polymère (19). Ce dernier constitue au moins une partie de la matrice du panneau (10).
