    摘要: A multistage filament winding process for manufacturing a composite article using a dual chemistry formulation including the steps of (a) providing a dual chemistry formulation containing components to effectuate dual cure of the formulation; (b) winding fibers on a liner or on a mandrel; (c) impregnating the wound fibers of step (b) with the dual chemistry formulation; (d) activating a first reaction (A) by UV or thermal-free radical initiation sufficient to form first macroscopic gels and to allow the first macroscopic gels to phase separate from the remaining substantially unreacted components in the formulation; (e) optionally, activating a second reaction by heating through IR lamps or other heating apparatus and controlling the second reaction sufficient to form second macroscopic gels subsequent to the formation of the first macroscopic gels which have gelled and phase separated in the formulation; (f) repeating steps (a)-(d) until a composite article having a predetermined thickness is formed; and (g) heating the formed composite article of step (f) sufficient to form a final composite article product having a predetermined glass transition temperature; a cured thermoset article prepared by the above process; and a process for manufacturing spoolable pipe.

    摘要: The present invention discloses a structure comprising a plurality of three dimensional cells, wherein each cell comprises exterior walls defining an interior void wherein the walls comprise a plurality of struts and windows, the struts forming borders for the plurality of windows, wherein the struts have a plurality of pores. The present invention further discloses a viscoelastic foam having a ratio of elastic modulus (E′) at 20° C. to 25% compression force deflection (CFD) of 25 to 125.
