Preparation and torsion test of all-carbon fiber composite drive shaft with flange and shaft tube integrated molding
The existing carbon fiber composite drive shaft is usually composed of metal flange and carbon fiber composite shaft tube.The metal flange has heavy weight and needs to be connected to the shaft tube by adhesive bonding or riveting,so it can increase the inertia during starting or braking and affect the overall performance.Therefore,the preparation and torsion test research of all-carbon fiber composite drive shaft with flange and shaft tube integrated molding were presented.The all-carbon fiber compos-ite drive shaft was prepared using the tube coiling and flange flanging and wrapping process,the total length of the drive shaft was 1 980 mm,and the layering scheme was[(±45°)32/45°].At last,the static torsion and torsional fatigue tests were conducted.Accord-ing to the test results,the all-carbon fiber composite drive shaft has no damage under 12 000 N·m static torsion test,and its torsional stiffness is 1.93×105 N·m/rad.No damage occurs in the torsional fatigue tests with 200 000 times,which met the normal working requirements.The maximum residual torsional stiffness in the torsional fatigue test is 2.02×105 N·m/rad,and the minimum residual torsional stiffness is 1.89×105 N·m/rad.
