Abstract
Thermoplastic materials are joined to non-thermoplastic materials such as thermosetting materials by laser radiant energy which causes the thermoplastic material to flow onto the thermosetting material, preferably into a notch or groove or over a shoulder or lip to form a joint by mechanically locking the materials together.
Claims6
A method for joining thermoplastic material to thermosetting material comprising the steps of:
- forming a projection locking surface on the thermosetting material,
- causing the termoplastic material to melt and flow merely by projecting a laser beam to impinge upon the thermoplastic material at the area adjacent to said locking surface,
- the melted material flowing out of its own plane over said locking surface to form a joint at the interface between the thermosetting and thermoplastic materials.
