    摘要： A machine for filament winding, in particular on a liner for the manufacture of tanks, comprising a displacement system able to drive a body in rotation around its longitudinal axis (A) and to effect a relative displacement of the body with respect to winding means. The winding means comprise a rotating support, mounted so as to rotate around a rotation axis (B), on which are mounted at least two winding systems, each winding system comprising a winding head associated with storage means, so that, by rotation of said rotating support around its rotation axis (B), each winding system can be displaced into an active position for winding fiber via its winding head, and an inactive position in which an operator can perform maintenance operations.

    摘要： A system for producing an impregnated fiber roving, the system including a feed unit having a spool with a fiber roving, an impregnation unit configured for applying liquid matrix material onto the moving fiber roving fed from the feed unit, a matrix supply unit fluidically connected to the impregnation unit for supplying liquid matrix material to the impregnation unit, a tension sensing unit adapted to determine a tension of the fiber roving fed from the feed unit to the impregnation unit, a speed sensor for determining a speed of the fiber roving fed from the feed unit to the impregnation unit, control means configured for monitoring the tension determined by the tension sensing unit and adapting the speed of the fiber roving depending on the monitored tension, monitoring the fiber roving speed determined by the speed sensor and adapting the supply of liquid matrix material based on the monitored fiber roving speed.

    摘要： A joint for a composite frame includes a first composite rod, a first shell abutting the first composite rod, a second shell abutting the first composite rod and disposed opposite the first shell relative to the first composite rod. The first and second shells are joined together such that composite rod is fixed therebetween. A method of forming joints of composite frame includes forming a composite frame by interconnecting a plurality of composite rods formed by an Automated Fiber Placement (AFP) manufacturing method around a mandrel, applying a first shell to the plurality of composite rods at a first location where composite rods are interconnected, applying a second shell at the first location opposite the first shell relative to the composite rods, and joining the first and second shells together with the composite rods at the first location disposed between the first and second shells.

    摘要： Automated methods of forming composite structures may include applying fibers having various predetermined lengths to a removable backing material to form a net shape or near net shape pattern for forming a composite structure having a varying transverse cross-section. Sheets of composite material may comprise strips of composite material adhered to a backing material in a net shape or near net shape pattern for forming a composite structure with a varying transverse cross-section. Further methods of manufacturing sheets of composite material may comprise applying fibers having various predetermined lengths to a removable backing material in a net shape or near net shape pattern for forming a composite structure having a varying transverse cross-section. Pattern preparation systems may include a material placement device programmed and configured to apply fibers having various predetermined lengths to a removable backing material. Forming systems may include an indicia locating device.
