Abstract
The mechanical behaviour and failure mechanism of the reinforcing fibres and the polymer matrix of a circular composite ring, subjected to radial pressure and cryogenic thermal loading, and the design of a thick composite arch, are studied using nonlinear finite element analysis. The rings are sections of a pultruded 0.203 m × 0.0065 m (8 in × ¼ in) diameter × thickness, polyester-glass pipe, reinforced in both the axial and circumferential directions. The arch is 1.0 m in radius, 0.1 m thick and 0.065 m wide. Circular rings of pultruded polyester-glass may be used at the tips of the composite radial structures, supporting the round aluminum rippled conductors of superconductive energy storage magnets.
