Abstract
A carbon composite aircraft brake disc (10, 50, 60, 110, 120) is manufactured to include internally an insert member (12, 14, 18, 24, 28, 32, 36, 42, 52, 115, 125) which effects positive vibration damping for the disc (10, 50, 60, 110, 120) during operation of the brake (100). The insert member (12, 14, 18, 24, 28, 32, 36, 42, 52, 115, 125) may be a graphite material, paper, or cloth material which is introduced into the interior of material utilized for manufacturing the carbon composite aircraft disc (10, 50, 60, 110, 120). After manufacturing of the brake disc (10, 50, 60, 110, 120) is completed, the brake disc comprises a single integral carbon composite brake disc (10, 50, 60, 110, 120) having disposed completely internally therein the insert member which provides a discontinuity that effects efficiently positive vibration damping of the disc (10, 50, 60, 110, 120) during operation of the aircraft brake (100) in which the disc is located.
