    • A method of making a fenestration framing member includes providing a core of desired cross section and geometry lengthwise of the core. A fiberglass mat is placed around the core to form a fiberglass-enclosed core, and resin is vacuum infused into the mat to form a fenestration framing member that includes fiberglass-reinforced resin enclosing the core. The starting core and the final fenestration framing member preferably are of curved geometry lengthwise of the core and member. The step of vacuum infusing resin into the mat surrounding the core preferably is carried out by placing the fiberglass-enclosed core into a vacuum enclosure, preferably a vacuum bag, and connecting the vacuum enclosure to a vacuum source and a resin source.
    • 制造开窗框架构件的方法包括提供具有期望的横截面的芯和纵向的芯的几何形状。 玻璃纤维垫被放置在芯周围以形成玻璃纤维封闭的芯,并且将树脂真空注入垫中以形成包含封闭芯的玻璃纤维增​​强树脂的开窗框架构件。 起始芯和最终的开窗框架构件优选地在芯部和构件的纵向上具有弯曲的几何形状。 优选通过将玻璃纤维封闭的芯放置在真空包装中,优选真空袋中并将真空外壳连接到真空源和树脂源来进行将围绕芯的真空注入树脂的垫片的步骤。
