Resin impregnated multi orientation composite material

A composite material made of multiple filament bands is disclosed. The filament bands are wound to create a composite material. The filament bands may be impregnated with a solid or semi-solid resin. The filament bands are wound in multiple orientations to form a sheet of composite material. Additionally, the composite material may be made to have a varying number of layer and fiber orientations throughout the sheet of composite material. In another embodiment, a composite component requiring multiple layers and fiber orientations may be substantially manufactured during a filament winding process.

20250091283 · 2025-03-20 ·

A filament winding machine and method for winding a fibrous ply onto a body, the machine comprising at least one winding head having a final guide member, a movement system capable of rotating the body and of moving the body relative to the winding head, and a resin application system capable of applying a resin composition to the fibrous ply. The resin application system comprises a nozzle capable of coating one of the main faces of the fibrous ply with a resin composition upstream of the final guide member and a feed device capable of supplying the nozzle with the resin composition at a flow rate that is regulated according to the travel speed of the fibrous ply.

Winding head for at least two fiber strands, and winding method for producing fiber-reinforced components

A winding head includes a first supply spool for receiving a first fiber strand and a second supply spool for receiving a second fiber strand, an impregnation unit through which the first fiber strand and the second fiber strand can be guided for impregnation with liquid resin, a first deflection roller assigned to the first supply spool, and a second deflection roller assigned to the second supply spool. The winding head further includes a bundling roller, at which the first fiber strand and the second fiber strand can be combined to form a complete fiber strand upstream of the impregnation unit, and which is arranged downstream of and spaced apart from the first deflection roller and the second deflection roller. A spreading roller is arranged downstream of and spaced apart from the bundling roller to form two fiber spreading sections.
