<p>An elongate composite element looking like a monofilament is made from parallel, very long, symmetrical fibers impregnated with a heat cured resin. The fibers have an initial expansion modulus≥2.3 GPa, elastic deformation in compression≥2% and greater resistance to rupture when compressed than when under tension. Independent claims are included for the following: (a) An elastomeric strip reinforced with the above elements. (b) An element as above where the fibers form 60 - 80% of the total mass and its density≤2.2. Preferred Features: The element has a circular cross section≥0.4 mm. The elements are arranged side-by side in superposed layers laid at opposite angles.</p> |
