摘要： A method of forming ablative insulation coatings on aerospace structures and articles produced thereby. The method includes forming a mold having a cavity configured to complementarily receive at least a portion of the structure and directly molding the ablative coating to a surface of the structure by introducing a prepared ablative mixture, such as an epoxy resin, into the mold. The process may desirably include curing at atmospheric pressures to reduce the expense and equipment required in carrying out the process. The method of applying the ablative coating further includes features such as varying the thickness of the ablative coating from one portion of the component to another. Control of the thickness may be effected through use of spacers embedded into the ablative coating and formed of the same or similar material previously cured prior to placement in the mold.

摘要： A method of forming a composite elongated member is provided. The method includes forming a preform having at least one of a groove and a ridge. The at least one of a groove and a ridge extends a length of the preform. The preform is then shaped to create the elongated member having a desired cross-sectional shape with at least one curve formed along at least one of the at least one groove and ridge.

摘要： An apparatus for fiber impregnation for use in a fiber placement system is disclosed. Resin is impregnated in the fiber rovings as they pass through a manifold. The manifold includes grooves for the fibers to travel, a reservoir to receive the resin and channels for the resin to flow to the individual fibers for impregnation. A control system measures and monitors the fiber speed and then mixes, pumps and delivers the desired quantity of resin to the tows for impregnation.
