In a curtain wall of metal-stud-frame type in which a metal frame is attached to the back surface of a concrete panel through a flexible anchor, a self-supporting type solid, knitted goods formed by knitting fibers in three dimensional directions with a pitch between each fabric exceeding 5 mm is buried in the skin of said concrete panel and the forward end of said flexible anchor is held in the space of cell of said solid, knitted goods. The curtain wall has a high bending strength and is easily manufactured and, therefore, suitable for use in external materials of buildings.

A method of making a curtain wall building panel, comprising the steps of: providing a plurality of first sets of first fibers, each of said first fibers extending substantially parallel to a first direction, each of said first sets containing a plurality of said first fibers disposed in a respective plane and spaced from each other by respective first distances, each of said respective planes of said first sets being disposed substantially parallel to each other and being spaced from each other by respective second distances, a plurality of second sets of second fibers, each of said second fibers extending substantially parallel to a second direction perpendicular to said first direction, each of said second sets containing a plurality of said second fibers disposed in a respective plane and spaced from each other by respective third distances, each of said respective planes of said second sets being disposed substantially parallel to each other and to said respective planes of said first sets and being spaced from each other by said respective second distances, said first fibers of each of said first sets being connected to said second fibers in an associated one of said second sets at intersection points, a plurality of third fibers extending substantially parallel to a third direction substantially perpendicular to both said first and said second directions, each of said third fibers being connected to an associated one of said intersection points in each of said first and second sets, said first, said second and said third fibers being formed from one or more of the group consisting of carbon, aramid, glass, formalized polyvinylalcohol or polyethelene, whereby said first, second and third fibers comprise edges of at least one cell and define a self-supporting three dimensional braid, a frame spaced from said braid and extending in a plane substantially parallel to said respective planes of said first and second sets, and at least one flexible anchor extending between said frame and said braid, a first end of said anchor being connected to said frame and a second end of said anchor being connected to said braid; providing a mold having sides defining a shape corresponding to, and a volume greater than, said braid; placing said braid within said mold with said braid spaced from said sides; placing a curable building material within said mold to encompass, and essentially fill said at least on cell of, said braid and to encompass a portion of said at least on anchor; allowing sufficient time for said curable building material to become self-supporting; and removing said braid, and therefore said building material, from said mold.
