摘要： A method of debulking a fiber preform includes debulking a three-dimensional fiber preform from a first size to a second, smaller size. A solvent may be infiltrated into the preform to distribute a tackifier material therein. The solvent is then removed and the dried preform is compressed to the smaller size such that, upon removal of the pressure, the tackifier material causes the preform to substantially remain at the smaller size.

摘要： A component to be repaired includes a relatively rigid plate. On a surface that may have been subject to fracture, a resin material is first laid down, then a relatively flexible material is positioned outwardly of the resin material to repair the barrier. A part may also be formed initially with the flexible material. In another feature of this application, a method of forming a barrier includes providing a composite material, and applying a relatively flexible material on a surface of the composite material, and concurrently molding the relatively flexible material with the composite material using a composite mold.

摘要： A method and system is described herein for repairing a part used in a gas turbine engine, which has a damaged or worn lubricant layer bonded to a surface of the part. After removing the damaged or worn lubricant layer, a polymeric adhesive may be used to attach a replacement lubricant layer to the metal surface. The polymeric adhesive may be a film or a paste. In some embodiments, the adhesive includes a non-metallic filler. The polymeric adhesive is stable at an operating temperature of the part to which it is attached. In one embodiment, the adhesive is polyimide, which is well-suited for use in a high pressure compressor of the gas turbine engine that operates at high temperatures. In other embodiments, the adhesive is bismaleimide (BMI) or cyanate ester.

摘要： A substantially microcrack- and blister-free composite can be made by drying an addition-type polyimide molding compound under suitable conditions to remove excess moisture. The molding compound includes a mixture of a polyimide resin and a plurality of carbon reinforcing fibers less than 3 mm long. The molding compound is placed into a heated material reservoir and transferred to a heated molding tool with a heated transfer ram. The ram establishes a molding pressure in a mold cavity in the molding tool sufficient to cure the molding compound into the desired composite. The molding compound is transferred to the mold cavity such that the molding compound is heated to a molding temperature at a rate of at least about 85.degree. C./min. The molding pressure and temperature are maintained in the mold cavity for a time sufficient to cure the molding compound into the desired composite. The composite is cooled and then heated to a suitable post-cure temperature at a rate sufficient to permit residual volatiles in the composite to diffuse out of the composite. The composite is held at the post-cure temperature for a sufficient time and then cooled. The invention also includes an article made by this method and a vented molding tool used in the method.
摘要翻译： 通过在合适的条件下干燥加成型聚酰亚胺模塑料以除去多余的水分，可以制备基本上不含微裂纹和无起泡的复合材料。 模塑料包括聚酰亚胺树脂和少于3mm长的多个碳增强纤维的混合物。 将模塑料置于加热的材料储存器中并转移到具有加热的转印柱的加热模制工具中。 该冲头在模制工具中的模腔中形成足够的成型压力，以将模塑料固化成所需的复合材料。 将模塑料转移到模腔中，使得模塑料以至少约85摄氏度/分钟的速率加热到模塑温度。 模塑压力和温度在模具腔中保持足以将模塑料固化成所需复合材料的时间。 将复合材料冷却，然后以足以允许复合材料中的残留挥发物扩散出复合材料的速率加热至合适的后固化温度。 复合材料在固化后温度下保持足够的时间，然后冷却。 本发明还包括通过该方法制造的制品和在该方法中使用的通风模制工具。
