Ultrasonic welding of fibre reinforced thermosetting resin sections |
| abstract |
A process for forming a permanent join between two sections of fibrous material contained in a thermosetting resin matrix, comprising overlaying the two sections and subjecting the overlaid sections to ultrasonic welding to form a permanent join between the two sections, wherein there is no significant change in the sub-ambient Tg of the fibrous material contained in the thermosetting resin matrix in the region of the permanent join. Preferably, the thickness of the permanent joint is from 50% to 150% of the average thickness of each of the two overlaid sections before they are overlaid. The ultrasonic welding may be carried out by contacting the overlaid sections with a sonotrode while they are supported by an anvil; the anvil may be a flat plate, a drum or a roller. The sonotrode preferably has a contact surface which covers the entire area of overlap. The process may be used to join the ends of tape which are to be fed to an automatic tape lay up process. The thermosetting resin may comprise an epoxy resin. The invention also relates to sections of fibrous material contained in a thermosetting resin matrix permanently joined together by a process according to the present invention. |
