ABSTRACT:
A curtain wall building panel having a metal frame secured to the reverse side of a concrete panel with flexible anchors. A 3-D braid is formed in such a manner that non-metallic fibers are braided in the three directions at a pitch of 5 mm or more and have a self-supporting characteristic. The braid is embedded in the concrete panel and the front ends of the flexible anchors are secured to cell spaces in the 3-D braid. The curtain wall exhibits excellent bending strength, can be easily manufactured and can be used for exterior finish of multistory buildings. A method of making the building panel is also disclosed.
