Systems and methods are provided for fabricating a hybrid composite part. A method includes braiding a first set of fibers to form a weave having a closed cross-sectional shape, braiding a second set of fibers into the weave that are chemically distinct from the first set of fibers, impregnating the weave with a resin, and hardening the resin within the weave to form a hybrid composite part.

Hybrid braided composite parts

A system for manufacturing a particulate-binder composite article including a mold defining a mold cavity, a first opening into the mold cavity, and a second opening into the mold cavity, a mass of a particulate material received in the mold cavity, a binder source in selective fluid communication with the mold cavity by way of the first opening, the binder source including a binder material, a first filter disposed across the first opening, the first filter being permeable to the binder material and substantially impermeable to the particulate material, and a second filter disposed across the second opening, the second filter being permeable to air and substantially impermeable to the particulate material.

Systems for manufacturing a particulate-binder composite article

A system for manufacturing a composite article includes a resin-wetting control layer configured to be placed in contact with a composite ply of a composite preform. The resin-wetting control layer is configured complementary to a ply surface of the composite ply.

A system for manufacturing a composite article may include a resin-wetting control layer configured to be placed in contact with a composite ply of a composite preform. The resin-wetting control layer may be configured complementary to a ply surface of the composite ply.

Method of manufacturing a composite article

Techniques and apparatus for providing a fly away caul plate are disclosed. In an embodiment, a method for curing a composite structure includes placing a pre-cured caul plate proximate an uncured composite lay-up, the lay-up may or may not include one or more stiffeners extending substantially perpendicular to the lay-up surface, the caul plate including an aperture for receiving the at least one stiffener. A force may be exerted against the caul plate to engage the composite lay-up. Heat and/or pressure may be applied to the composite lay-up to cure the stiffener panel and co-bond the caul plate to the composite lay-up.

Fly away caul plate

A hollow core composite assemblyis provided, including a hollow core basehaving at least one open core surface, a bondable solid filmapplied to the open core surface, at least one dry face plylaid up dry and placed on top of the solid film, and a liquid resinapplied to the at least one dry face plyand then cured.
