Definitions
- the present invention concerns a bullet- and splinter- proof material.
- bonded layers for this purpose each layer consisting of a fabric-type structure (woven or non-woven fabric, loose fibres, for example nylon, carbon or Kevlar, a Dupont registered trademark, or other aromatic polyammides or aramides) which is impregnated or in any event coated with plastic material.
- a fabric-type structure woven or non-woven fabric, loose fibres, for example nylon, carbon or Kevlar, a Dupont registered trademark, or other aromatic polyammides or aramides
- plastic material thus far in use there are difficulties in achieving a homogeneous material, as far as ballistic proofing characteristics are concerned, especially when manufacturing large items.
- the material used up to now has a relatively high unit weight, rendering the items produced too heavy or too bulky. Normally anti-ballistic material is also difficult to form.
- the aim of the present invention is to provide a material having high ballistic proofing over its entire surface, that also has a low unit weight and is preferably easy to process.
- the above aims have been achieved with a material consisting of loose fibres, spun products, woven and non-woven fabrics, impregnated or coated with cellulose acetate butyrate or cellulose acetate propionate or ethyl vinyl acetate as such or plasticated or mixed with other resins the content of which is lower than 50%.
- the above described material is preferably produced by immersing the base layer in a tank containing a solution or a dispersion of the above-mentioned resin and then subjecting it to heat treatment to allow the solvents or the water to evaporate.
- the amount of product deposited on each layer is adjusted simply by changing the viscosity of the solution or the dispersion or by constantly squeezing the base. In this manner a high degree of evenness is easily achieved in the production of each layer. Heating is preferably carried out in a heated vertical tunnel through which the material is passed, an impregnated product being obtained that feels soft and is therefore easily shaped.
- the material is heated to a higher temperature, 120-130°C, the result is a semi-rigid impregnated product suitable for flat shapes.
- the material according to the invention offers a series of advantages. As far as its characteristics are concerned, it has a lower unit weight than other known materials having the same strength, its ballistic proofing is even and remains unchanged by time. As far as its formability is concerned, being produced with a thermoplastic resin the material lends itself to re-shaping and re-forming: all that is required is heating to make the hardened product become plastic again. As regards cost, the production cycle is economical because the process does not involve any critical step, thus it requires only limited supervision.
