The GE90 wide chord fan blade
incorporates over 1000 plies of uni-directional
tape and fabric to form a three dimensional airfoil shape. Thickness
varies
from up to four inches in the root of the blade to only a quarter of an
inch in the airfoil. In order to ensure structural integrity, each
blade
must pass high resolution ultrasonic and x-ray testing. Metal
hardware bonded to the edge of the blade provides erosion protection.
The
GE90 engine equips the Boeing 777 airliner.
Bypass ducts using carbon fiber and high temperature PMR15 resin provide the performance of a low weight part with resistance to temperatures up to 600ºF. These parts require high temperature cure technology capability and intricate five axis machining. Fan ducts of honeycomb sandwich construction require metal/honeycomb bonding, sound suppression, hardware riveting and assembly capability. |

Containment
cases are application critical
parts manufactured using graphite wrapped
honeycomb bonded to metal rings and reinforced with kevlar. These parts
require sophisticated cure technology to accommodate differences in
thermal
expansion during the cure process between metal and composite.
Other parts manufactured by CFAN range from engine bleed ducts made of carbon fiber and BMI resin to fiberglass and epoxy fairings up to twenty ft. in length and seven ft. in diameter. |
