Definitions

  • the invention pertains a laminate, stack, panel and formed part comprising at least one laminate of unidirectional arranged polymeric tape, in particular for anti ballistic applications.
  • This invention proposes a laminate for anti ballistic purposes which comprises unidirectional placed polymeric tapes with a E-modulus of an individual tape of at least 50 GPa and a square meter weight of the laminate above 150 grams.
  • the laminate is more easy to produce, is less fragile and to handle during production. And with the same production velocity, a higher output due to the thicker laminates is achieved.
  • a panel from a certain thickness needs fewer layers and can therefore be faster produced.
  • the laminate according to the invention exhibits a square meter weight above 210 grams, more preferably above 300 grams.
  • the tapes for the laminate according to the invention may be connected to each other only by means of hot compaction or selective melting and no adhesive is used for the laminate.
  • the laminates according to the invention are connected by means of an adhesive.
  • the adhesive content of the laminate may be at most 20% of the total weight of the laminate.
  • the square meter weight of the tapes in the laminate is at least 150 grams, more preferably at least 180 grams, most preferably at least 210 grams.
  • the final total panel weight of the panel constructed from thin laminates and from thick laminates was identical. The difference was the amount of laminates and the thickness of the laminates.
  • the laminate according to the invention comprises at least 2 unidirectional positioned drawn polymeric tapes, connect to each other by glue or thermo bonding.
  • glue at least two laminates are to be understood, which laminates have directions deviating from each other in an angle from 0 to 90 °, i.e. the laminates are not parallel to each other.
  • panel or “plate” contains a combination of two or more stacks in a rigid manner is meant, which can be achieved e.g. by applying pressure and temperature to the stack(s).
  • tape a highly drawn slitted film, an extruded mono-polymer, or bicomponent extruded drawn slitted films or co-extruded multilayer "monofilament", a so called SSE (solid state extruded) highly drawn film known as e.g. Tensylon, Pamaco and other equivalents is meant.

  • the most common polymers for these tapes are polyethylene, polypropylene, PET (Polyethylene terephthalate), PEN (Polyethylene Naphthalate), Polyamide, PPS and/or mixtures thereof.

  • Preferred adhesives or resins are e.g. lattices of Kraton, PU, Acrylics , but also dispersions of EAA, EMA, EVA ,OBC (Olefin Block Copolymer) (Infuse ® DOW) etc. or various solvent based/water based adhesives with chloroprene and alike.
  • Further suitable adhesives may be selected from the group consisting of polyethylene, ultra high molecular weight polyethylene, polypropylene, polyamide, polybutadiene terephthalate and polyethylene terephthalate, polyethylene naphthalate, polyvinyl alcohol, polyphenylidensulfide, copolymers of these polymers and mixtures thereof.

  • Two or more hard strike surface layers can also be combined with two or more of the panels, such as e.g. sandwiching the hard strike surface layers by the panels.
  • the low adhesive content in the stack according to the invention which has by nature a relatively high specific surface due to the many very small diameter filaments, in combination with the relatively small specific surface of the tapes, helps to absorb energy by delamination upon impact.
  • the multifilament yarns and tapes separate from each other when hit by e.g. a bullet which enables the energy to be absorbed and dissipated.
  • a possible variation is to connect the layers to each other by surface-fusing of the material within the stack with the lowest melting temperature to achieve a bonding of the layers in the laminate.
  • the laminate according to the present invention may comprise more than 2, e.g. 3, 4 or up to 25, even up to 50 or up to 100 monolayers of polymeric tapes all stacked in such a way that the direction of the polymeric tapes is the same in every monolayer
