Beim Bohren von kohlefaserverstärktem Kunststoff treten verstärkt Schädigungen wie Delaminationen und Faserüberstände auf. Mit dem Ziel die Bohrlochqualität zu verbessern, wurde der Einfluss der Werkstückeinspannung hinsichtlich Einspanngeometrie, -kraft und -material untersucht. Zusätzlich zur konventionellen optischen Delaminationsmessung wurde die äußere und die innere Delamination mittels Mikrocomputertomografie analysiert. Durch eine Optimierung der Einspannung konnte die Bohrlochqualität gesteigert werden.   When drilling carbon fiber reinforced polymers damages like delamination and fiber protrusion appear. Aiming to improve the drill hole quality, the influence of the fastening device with respect to fastening geometry, force and material is analyzed. In addition to the conventional optical delamination measurement, the outer and inner delamination is investigated by micro computer tomography. The optimization of the fastening device leads to a higher drill hole quality.

Carbon Fiber Reinforced

Fe–Ni alloys with low thermal expansion coefficients were deposited on carbon fiber reinforced carbon matrix composite (C/C composite) as metallization coatings via ultrasound-assisted electrodeposition. The interface was compact at the micrometer scale, and the micro-cracks and pores on the composite surface were fully filled with the deposited alloy. The interface shear strength reached 16.24 MPa, which was a significant improvement in comparison with that of the conventional electrodeposition. These results may have been due to the residual stress reduction, the joining area increasement, and the pinning effect enhancement.
