Abstract : Structural cores in the form of open-ended polyhedrons joined together along common edges or sides are generating high industrial interest because of the great strengths they possess relative to their weights. A structural core medium of interwoven fibrous filaments coated with plastic is highly satisfactory, but it has the disadvantage that it is very difficult, if not heretofore impossible to produce in other than planar, sandwich or cylindrical form. A jig for the fabrication of such cores has not come into existance. This invention provides a jig which makes possible the fabrication of such polyhedral structural cores. (Author)
