| Abstract: | The carbon fiber preforms formed by weaving(braiding) are densified to make carbon carbon pin bolts.The influence factors on carbon carbon pins such as weaving(braiding) methods,densification technologies,interface,and machinability are discussed.Pitch carbon matrix by high pressure pyrolysis has relative strong bonding to carbon fiber at interface. Fiber volume fraction is a dominant factor to affect the shear strength of C/C pins. 4D Braided carbon carbon composites with good machinability normally have higher fiber fraction and higher shear strength of 63.7 MPa for example. |
