Abstract: | Laser welding of transparent and semi-transparent thermoplastics using layers of carbon nanotube (CNT) web as absorbant is reported. Single lap shear specimens were manufactured placing the layers of CNT-web between two polyethylene terephthalate glycol-modified (PETG) sheets, that were successively irradiated with laser power at a wavelength of 1064 nm. Optical analyses were performed to assess the transmittance of the joint under different configurations; for the single layer of CNT web a transmittance of 83 %, in the visible range, was obtained after welding. Single-lap shear tests were performed and a shear strength of 23 MPa was obtained when using one layer of CNT-web. The investigated technology allows using a solid film as laser absorbing material, replacing conventional liquid or dye that need to be processed and applied on the surface before welding, thus speeding up the manufacturing process. |
