Abstract: A method of manufacturing a composite core including wrapping each of a plurality of mandrels with a composite material and stacking the plurality of mandrels wrapped with the composite material in a tool. A heated fluid may be moved through an interior of the plurality of mandrels to controllably heat the composite material in a curing process. A pressure may be controllably applied to the tool with a bladder during a curing process. A tooling system for manufacturing a composite core is also discussed.

Abstract: A method of wrapping a plurality of mandrels with a composite material can include rotating each mandrel at a rotational speed; translating each mandrel at a translation speed; positioning each mandrel back to back such that an aft face of a preceding mandrel is approximate to a forward face of a trailing mandrel; and sequentially wrapping each mandrel with the composite material in a helical orientation.

Abstract: A method of joining a first bulk composite core and a second bulk composite core by applying an adhesive to a surface network of the first bulk composite core; inserting a plurality of mandrels into a plurality of cell members of the first bulk composite core and a plurality of cell members of the second composite core, thereby aligning the cell members of the first bulk composite core to the cell members of the second bulk composite core; pressing the respective surface networks of the first bulk composite core and the second bulk composite core together with the adhesive located therebetween; and curing the adhesive.

Abstract: A method of manufacturing a composite core can include: wrapping a mandrel in a mandrel wrapping process by securing a mandrel with a winding jig; orienting the composite material at a wrap angle to the mandrel; and depositing the composite material around a circumference of the mandrel. The method can further include assembling the wrapped mandrels in a tool and applying a pressure to the composite material during a curing cycle.

Abstract: A method of cutting a wafer of composite core from a bulk composite core includes stabilizing the bulk composite core with a fixture, the bulk composite core having a plurality of tube members. The method also includes cutting through each of the tube members to create the wafer while the bulk composite core is stabilized by the fixture.
