Definitions
- U.S. Patent no. 5,237,758 to Zachman this uses semi-elliptical sections intersecting at loops with adjacent webs of adjacent loops intersecting with flexible rods directed through the intersecting loops to minimise lateral displacement of adjacent webs.
- U.S. Patent no. 5,285,583 to Aleven this uses a protective layer composed of plastic and including a flexible forepart portion having an insole board bonded to its bottom surface and a fabric liner bonded to its top surface during the process of moulding the protective plastic layer. The plastic used by Aleven is molten plastic injected in the final bonding process.
- Figure 4 is a vertical cross-sectional view of a boot having a fourth embodiment of the sole construction according to the present invention.
- polyester and/ or polyether-based polyurethane is injected into the mould cavity containing the outer (lower) sole 14 at the base of the sole to form the intermediate sole 15.
- the polyurethane after injection into the mould has a typical density of ⁇ 1000 kg/m 3 .
- the polyaramid layers 18 as described in the embodiments above are further interwoven with carbon graphite fibres having 12K TOW and a tensile strength of 470,000 PSI and modulus of 35 million PSI with the boot sole 13 being made in the same manner as described above.
- the use of interwoven carbon graphite fibres has the advantage of further increasing strength and stiffness and of improving wear resistance.
- a layer of composite S-Glass fibres can be added into the middle or upper sole 14, 15 (see Figures 4, 4-A and 4-B).
- the boot sole 13 incorporating the layer of S-Glass fibres 41 , 42 allows for protection against hot gasses with a temperature resistance of 815 degrees Celsius for the very brief duration of the blast.
