Rework press assembly for component rework systems and methods of using the same
A rework press assembly for reworking a dimensionally non-conformant component is provided. The rework press assembly includes a frame, a die coupled to the frame and configured to contact a first portion of the component, and a ram. The ram is coupled to the frame opposite the die with respect to an axis of the rework press assembly and is configured to contact a second portion of the component. The ram and the die define a component cavity therebetween. At least one of the die and the ram has a first length, relative to the axis, in response to the rework press assembly being at a first thermal condition. The at least one of the die and the ram has a second length, relative to the axis, in response to the rework press assembly being at a second thermal condition, and the second length is greater than the first length. |

Method of shaping composite blade
Provided is a method of shaping a composite blade made of a composite material by curing prepreg in which reinforcing fibers are impregnated with resin. A foaming agent disposed in an internal space of the composite blade contains a plurality of foaming bodies and foaming agent resin. The foaming bodies foam by being heated. The foaming agent resin cures by being heated. The foaming bodies include low-temperature side foaming bodies and high-temperature side foaming bodies. The low-temperature side foaming bodies foam in a low temperature range during a curing step. The high-temperature side foaming bodies foam in a high temperature range corresponding to temperatures higher than the low temperature range during the curing step. |

Composite component void repair
Methods for repairing composite component voids are provided. For example, one method comprises locating a void in a composite component and subjecting the composite component to a process for repair. The process for repair includes creating a flow path through the void, applying a filler material to the composite component at the flow path, and processing the composite component having the filler material. In some embodiments, the flow path has a first opening on a first side of the composite component and a second opening on a second, opposite side of the composite component. In other embodiments, at least one portion of the flow path extends at a first angle with respect to a lateral direction defined by the CMC component, and at least another portion extends at a second angle with respect to the lateral direction. |
