Flexlock non-textile fabrics use intimately linked elements that are formed from formable, preferably solid phase forgeable materials into generally triangular shapes with hinging connection features along edges of a generally triangular overall shape. These hinging connection portions permit other elements to rotate about axes that intersect at intersections. Buttressing portions are located near these intersections and include cylindrical or conical shapes that abut the buttressing portions of adjacent formed elements. This abutting can occur even when adjacent elements are rotated or twisted out of a common plane. Connection portions include direct formed engagements with knuckles of the other elements. These connection portions and the engaged knuckles can include headed pintles, axles, or oppositely facing conical protrusions, and may be configured to permit the non-textile fabric to bend on itself within its own thickness without undue strain on the connection features.
