<p>A composite material comprises a coherent, three dimensional network of structurally interconnected polymeric fibres impregnated with an extensible resin matrix having a pliable resilient nature, which exhibits the propensity for increasing strength and toughness with repeated load cycling. Pref. (1) the fibres are polypropylene and the matrix is silicone resin; and (2) the fibres are polypropylene and the matrix is a flexible epoxy resin. Used in the mfr. of flexible electrical components, belts for mechanical power transmission, seals, O-rings, tyres, gaskets, and other applications requiring high strength with elastomeric characteristics.</p> |
