Improved technique for attaching aluminum flange to aramid/epoxy duct prevents subsequent development of cracks in joint during thermal stress. Flange butted against cylindrical mold on which duct is fabricated. Flange has tapered neck so will nest in duct opening. Epoxy-impregnated aramid tape wrapped around mold so tape overlaps flange. While tape is wrapped, pressure applied to it and inside of flange as heated uniformly to maximum expected operating temperature. Heat and pressure maintained until aramid/epoxy laminations have cured.
