Abstract: A method for joining thermoplastics to glass comprising placing a sheet of continuous glass filled thermoplastic composite under glass; applying a predetermined amount of force on the bottom of the composite to achieve adequate contact and compaction between the composite and the glass; using a laser with a predetermined wavelength having a predetermined spot size to apply a predetermined amount of power to a predefined region of the composite and the glass at a predetermined speed, thereby creating a weld between the composite and the glass; cooling the joined materials for a predetermined period of time while still under compaction pressure; and removing the compaction pressure to access the joined materials.
