Abstract
This application relates to metal alloy knitted fabrics for high temperature insulation. Metal alloy knitted fabrics, thermal protection members formed therefrom, and methods of construction thereof are disclosed. This unique ability to knit drapable high temperature metal alloy wire allows near net shape generation at production level speeds. In addition, ceramic insulation can also be integrated at the same time to provide enhanced thermal protection. By providing a cover that withstands higher operating temperatures than stainless steel, the metal alloy knitted fabrics described herein overcome the limitations of current welded stainless steel mesh seal covers and are resistant to abrasion and clogging, capable of being a separate seal layer or as Part of an integrated sealed construction that can accommodate tight curvature changes to achieve complex shapes without wrinkling or buckling, and can be joined, sewn or mechanically fastened during knitting without welding.
Description
technical field [0001] Embodiments described herein relate generally to knitted fabrics, and more particularly to metal alloy knitted fabrics for high temperature applications, components formed therefrom, and methods of construction thereof. Background technique [0002] In many high temperature applications, such as aircraft structures, heat seals are often used between opposing faces or components. Typically, the heat seal member provides a thermal barrier that will be subjected to specified conditions (eg, exposure to temperatures in excess of 1000 degrees Celsius for a period of time greater than 15 minutes). These opposing components are subjected to operating load vibrations and repeated opening and closing during operation and maintenance procedures. As such, these heat seal components are subject to a high degree of wear and potential for damage. [0003] Current techniques for making heat-sealed members include the use of multiple layers of materials including, f...
