    摘要: Mandrels of various configuration, and action, including collapsible mandrels, to be used in forming composite articles with preselected three dimensional shapes and construction are disclosed and described. In one aspect, such a mandrel may have a plurality of discrete segments coupled about a longitudinal axis and collectively forming an enclosure with a substantially continuous exterior working surface. The working surface can have a network of intersecting grooves formed therein, and such grooves can cooperatively establish a substantially continuous interconnected lattice corresponding to the three dimensional geometric configuration to be imparted to a composite article formed. The mandrel may optionally include a removable core assembly to aid in collapse of the mandrel.

    摘要: Molded articles are described herein having a surface feature thereon, the articles being formed so as to include a polymeric composite material having reinforcing fibers in a polymeric matrix material. The surface feature(s) is created during heat molding of the polymeric composite material to form the article and the surface feature(s) include the polymeric matrix material and the reinforcing fibers therein. A method is also described which provides surface feature(s) to a molded article by providing a composite material as noted, placing the composite material in a mold for forming an article having a surface feature thereon, and molding the composite material using bladder inflation molding and pushing the reinforcing fibers into the surface feature of the molded article during molding using a heat molding process having a bladder inflation molding step, wherein the surface feature is created during the molding of the polymeric composite material to form the molded article and the reinforcing fibers are present in the polymeric matrix material defining the surface feature in the molded article.

    摘要: The present disclosure is drawn to a lattice support structure, comprising a plurality of fiber-based cross supports intersecting one another to form a multi-layered node. The multi-layered node can be consolidated within a rigid mold in the presence of resin, heat, and pressure. In another embodiment, a lattice support structure can comprise a first cross support comprising fiber material; a second cross support comprising a fiber material, said second cross support intersecting the first cross support; and multi-layered nodes located where the first cross support intersects the second cross support. The multi-layered nodes can comprise at least two layers of the first cross support separated by a least one layer of the second cross support. Also, one of the first cross support or the second cross support can be curved from node to node.
