Résumé : |
Carbon fibre-reinforced polymer (CFRP) materials are more and more used in various types of applicatons such as aircraft, automotive and wind harvesting systems. As production is product specific and costs are always an issue, trimming and drilling work is of special importance to minimize time and cost while constantly improving quality. Therefore, post-processing of CFRP materials is often accompanied by mechanical works like drilling or edge trimming before further use for asembly, where liquid lubricants are typically applied. High-precision holes, or dimensions (edge cutting) are needed to fulfil the requirements of the subsequent assembly process. |

- Fig. 1 : CFRP sample (lower part) and the corresponding SLE part (upper part - the visible side is adhesive tape) after a trimming experiment
- Fig. 2 : CFRP sample after drilling tests with SLE, after removal of SLE. Position of IR measurement is marked by a red dot
- Fig. 3 : Comparison of cleaned pure CFRP with CFRP next to trimming edge after SLE removal. An additional absorption peak is visible at 1?700-1,750 cm-1, indicating a slight adhesive tape residue remaining on the CFRP after SLE removal
- Fig. 4 : Schematic representation of the clamping sample plate and processing segments
- Fig. 5 : Application of SLE on the good side of the sample plate with drilling process from the back
- Table 1 : Surface free energy of CFRP before and after removing SLE
- Table 2 : XPS results of CFRP surfaces before and after use of SLE (with and without mechanical processing/cleaning) |
