  • Publication number: 20210362542
    Abstract: A non-pneumatic wheel includes an outer band, a hub and a plurality of spokes formed from a polyamine material. Each of the plurality of spokes is displaced to create pretension in the radial direction under a design load and the displacement is equal to or greater than the predetermined deflection of the outer band. The plurality of spokes is made from a polyamide material having a conditioned tensile modulus between 600 MPa and 3000 MPa, an equilibrium moisture content of no more than 1.5%, and a fatigue failure resistance that can withstand at least 1 million cycles.

  • Patent number: 10889031
    Abstract: The present invention is related to a method and an apparatus for curing a polymeric form. The method includes arranging an uncured polymeric form within a curing chamber (60) formed by a base member (20) and a constraining member (40). A thermal expansion member (30) is additionally positioned within the curing chamber (60) with the uncured polymeric form (70) such that the thermal expansion member and the uncured polymeric form are positioned between the base member (20) and the constraining member (40). The thermal expansion member (30) is heated to expand in size into an expanded state. In the expanded state the thermal expansion member (30) applies pressure to the uncured polymeric form (70) within the curing chamber. The expansion of the thermal expansion member (30) is maintained to maintain the application of pressure to the uncured polymeric form while the uncured polymeric form is being cured to form a cured polymeric form.
