    摘要: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure (33). The upper and lower skins (51a, 51b) and the core (22) are pulled automatically through tooling (23) where the skin material is wetted-out with resin and the entire composite laminate (33) is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine (24) that deposits "groupings of fiber filaments" at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that a extension of each "grouping of fiber filaments" remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station (39). Next the preformed composite laminate travels into a pultrusion die (26) where the extended "groupings of fiber filaments" are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die. The composite laminate continues to be pulled by grippers that then feed it into a gantry CNC machine (36, 37) that is synchronous with the pull speed of the grippers (34, 35) and where computerized machining, drilling, and cutting operations take place. This entire method is accomplished automatically without the need for human operators.

    摘要: The invention relates to a composite material, comprising a fiber composite (1) consisting of a plurality of fiber layers (2) embedded in a polymeric matrix, some of which preferably have fiber orientations (2) differing from the fiber orientations of the other fiber layers (2), in addition to a connecting area (4) formed by a reinforcement material (9) that is highly resistant to bearing pressure, wherein a transition area (3) is formed between the fiber composite (1) and the connecting area (4), in which the fiber layers (2) meet with the reinforcement material (9) of the connecting area (4). The invention aims at providing a composite material that is highly resistant to tensile strength and bearing pressure in the connecting area (4). This is achieved in that the connecting area (4) is formed by fiber layers (9) passing from the reinforcement material through the transition area (3) into the connecting area (4) and in that non-continuos fiber layers (2) meet with the corresponding layers (9) from the reinforcement material in the transition area (3) between the continuos fibers layers (2).
