Abstract
A rib-stiffened composite structure includes a composite face sheet having a continuous reinforcing fiber in a polymer matrix. A polymer core is in a grid pattern disposed on the composite face sheet, the grid pattern having a first series of paths crossing over a second series of paths. Material voids are formed in the spaces between the series of paths. A composite rib-cap is disposed upon an upper surface of the polymer core. The composite rib-cap includes a continuous reinforcing fiber in a polymer matrix. The fibers of the continuous reinforcing fiber of the polymer matrix of the composite rib cap are oriented in a direction along the first and second series of paths of the grid pattern of the extruded polymer core.
