Abstract | Joining technologies for incompatible materials are of high interest in many application areas as they allow the combination of the advantages of different materials. This study demonstrates a joining technique for transparent polymers and ceramics using commonly applied materials as examples, namely polymethylmethacrylate (PMMA) and low-temperature co-fired ceramics (LTCC). The concept is to use pre-structured ceramic surfaces with cavities that can be filled with polymeric material locally molten during laser transmission welding. The laser processing used to create appropriate surface textures is described. A variation of the surface pattern was performed and analysed with respect to mechanical bond strength. It was discovered that an increased structure density leads to and increased bond strength reaching a maximum value of 5.2 MPa. Furthermore a technique based on laser transmission welding to replicate surface topographies down to the nanometre scale is described. |
