MANUFACTURING METHOD FOR THERMOFORMING A FIBER-REINFORCED COMPOSITE LAMINATE
A manufacturing method for thermoforming a fiber-reinforced composite laminate with fiber rovings embedded within a thermoplastic matrix includes: mounting fiber rovings to a transport frame, the mounted rovings being arranged to form a support grid layer laterally framed by the transport frame, each roving being mounted on both ends under tension to the transport frame; placing a matrix material layup of thermoplastic material on top of the support grid layer, wherein the tension of the rovings and a density of the support grid layer are configured such that the support grid layer supports the matrix material layup; softening the matrix material layup by heating the support grid layer together with the matrix material layup within a heating station; forming a semi-finished composite laminate by pressing the support grid layer together with the softened matrix material layup; and consolidating the semi-finished composite laminate to form the fiber-reinforced composite laminate.
