摘要:
A manufacturing method of a reinforcing structure includes: preparing a stringer having a fiber exposure surface; arranging an insulation protection material to cover at least a part of the fiber exposure surface; arranging the stringer on a skin having an uncured resin component; and curing the skin after the arranging the stringer. The insulation protection material includes a composite material having a resin component and an insulative fiber component. The curing the skin includes curing the skin and the insulation protection material at the same time in the manufacturing method of a reinforcing structure, an edge glow discharge can be prevented without increasing a manufacturing process.
摘要:
Methods of forming a ceramic component and a high temperature mold for use therewith are provided. The method includes providing a fixture having a receiving surface configured to receive an unfired ceramic component. The method includes applying a continuous high temperature membrane to a surface of the unfired ceramic component. The method includes covering the continuous high temperature membrane and unfired ceramic component with a high temperature loose media. The method includes heating the unfired ceramic component to a firing temperature. The high temperature mold includes the fixture and a support structure forming a compartment surrounding the fixture. The mold allows the high temperature loose media to be contained within the compartment and to cover the continuous high temperature membrane. The continuous high temperature membrane and high temperature loose media are evenly distributed over the uncured ceramic component and operable to provide constant pressure during processing using the mold.

摘要:
A method for fabricating a carbon fiber composite part, for example, a sun shield structural assembly on a satellite. The composite part is fabricated on a carbon fiber/bismaleimide (BMI) composite tool, where a moisture barrier is positioned on the tool prior to carbon fiber part ply layers being positioned on the tool to prevent moisture from the tool from entering the part. In one embodiment, the moisture barrier includes cross-wise strips of aluminum foil. A wrinkle barrier is positioned on the moisture barrier before the carbon fiber part ply layers so that anomalies or wrinkles in the moisture barrier are not transferred to the part layers.
