Air Bonded, FOD Resistant Metal Matrix Fan Blades.

Abstract

A low cost air bonding process was developed for the fabrication of boron-aluminum fan blades from monotapes. Boron-aluminum systems of 8 mil boron-1100, 1100/2024 hybrid, and 6061 aluminum were successfully air bonded with properties equivalent to higher cost vacuum bonded material. The 8 mil boron-1100 system was selected for property characterization because of high Charpy energy absorption, 46 foot-lbs in + or - 15 deg orientation. The mechanical properties were compared to design requirements analytically determined for an advanced first stage fan blade, the J-101.
