    • 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.
    • 一种使用双重化学配方制造复合制品的多级纤维缠绕工艺,包括以下步骤:(a)提供含有组分的双重化学配方以实现配方的双重固化; (b)将纤维缠绕在衬垫上或心轴上; (c)用双重化学配方浸渍步骤(b)的卷绕纤维; (d)通过UV或无热自由基引发活化第一反应(A),足以形成第一宏观凝胶并使第一宏观凝胶与制剂中剩余的基本上未反应的组分相分离; (e)任选地,通过经IR灯或其他加热设备加热来激活第二反应,并且在形成已在配方中凝胶化和相分离的第一宏观凝胶之后控制第二反应足以形成第二宏观凝胶; (f)重复步骤(a) - (d)直到形成具有预定厚度的复合制品; 和(g)加热步骤(f)形成的复合制品足以形成具有预定玻璃化转变温度的最终复合制品产品; 通过上述方法制备的固化热固性制品; 和一种制造缠绕管的方法。
