Woven composite clutch friction member with dual-directional moduli of elasticity

A power transmission comprising:

• a torque-transmitting mechanism including:
• a friction member;
• an opposing reaction member, said friction member and reaction member being selectively engageable for transmitting power;
• said friction member having a friction surface for sliding contact with said reaction member, wherein said sliding contact is characterized by a coefficient of friction, said sliding contact acting to engage said torque-transmitting mechanism;
• said friction member having:
• a first material;
• and a second material;
• wherein said first and second material are woven, said friction material being characterized by a first modulus of elasticity in a first direction with respect to said sliding contact and a second modulus of elasticity in a second direction with respect to said sliding contact;
• and wherein said second modulus of elasticity is greater than said first modulus of elasticity.

A friction member for engagement in a torque-transmitting mechanism, the friction member comprising:

• a first material;
• and a second material;
• wherein said first and second materials are woven together to provide a friction surface, the friction member being characterized by a first modulus of elasticity in a first direction with respect to said friction surface and a second modulus of elasticity in a second direction with respect to said friction surface, wherein said second modulus of elasticity is greater than said first modulus of elasticity;
• wherein the woven friction member forms channels disposed in said first direction for transporting lubricant through the friction member in said first direction, said first modulus of elasticity being at least partially affected by lubricant transport through said channels to thereby at least partially increase said coefficient of friction;
• wherein the woven friction member forms channels disposed in said second direction for transporting lubricant through the friction member in said second direction, said second modulus of elasticity being at least partially affected by lubricant transport through said channels to thereby at least partially decrease vibrational shudder of the torque-transmitting mechanism;
• wherein said first and second materials are woven such that said friction surface is substantially formed by said second material;
• wherein said first material is disposed substantially away from said friction surface;
• wherein said first material includes fibers at least partially composed of poly-paraphenylene terephthalamide;
• and wherein said second material includes carbon-based fibers.
