Manufacturing Methods for Self-Sealing Fuel Lines.
Abstract
The techniques of brading FRP parts are developed. It relates to the establishment of those manufacturing process parameters to permit the use of the braiding process in manufacturing lightweight, reproducible, and economical self-sealing fuel lines for combat aircraft. Tests were conducted to determine the required overbraid on aluminum, stainless steel, and titanium fuel lines to eliminate deformation and control petalling which results from a impact with a .50-caliber, armor-piercing projectile. Two different reinforcing fibrous materials, FRP YARN AND PRD-49 yarn with epoxy as the matrix, were evaluated as the required overbraid. Braid angles and the number of plies were the sensitive parameters investigated in this pahse. The braiding process as a means of applying a cover over the sealant material is established. The manufacturing process is demonstrated. This was accomplished through a physical demonstration of the manufacturing process to invited aerospace industry and DOD PERSONNEL. (Author, modified-PL)
