ABSTRACT:
A method for producing a composite structural beam, particularly a sine wave beam, is disclosed utilizing as an essential feature, the bonding of the junctures of the sine wave web to the opposite flange areas of the beam with a fibrous braided material. The braiding is carried out during assembly of the composite web and composite flange components, prior to curing the components. In one embodiment the braided material extends along the entire height of the web, as well as along the flange areas, and is bonded thereto. In another embodiment the braided material does not extend along the entire height of the web, but only along the opposite edge portions of the web adjacent the junctures thereof with the flanges, the central portion of the web having no braided material applied thereto.
