| dc.description.abstract | Glass has many advantages such as high light transmission, wear resistance, high tempera-ture resistance and high chemical stability, and is widely used. In order to meet the needs of more applications, 3D or curved glass fabrication technology is also gaining more attention. One of the bendable glass technologies, laser bending, was demonstrated by Dongjiang Wu and his team in 2008, showing that a maximum bending angle of 24° could be achieved with a CO2 laser on thin glass of 150 µm thickness and 10 mm width. Although the feasibility was con-firmed, no other results on laser glass bending have been reported since then. It is clear that there are still many problems to overcome in laser glass bending: the main challenge is how to bend large angles on glass with large thickness and width. In this study, we first adopted the same scanning strategy as in the literature, but used a near-infrared (NIR), continuous laser (CW-laser) to bend soda-lime glass and borosilicate glass of different thicknesses and widths, instead of using a CO2 laser. In this study, three bending angles of 30°, 60° and 90° were suc-cessfully performed on soda-lime glass of 550 µm thickness and borosilicate glass of 1000 µm thickness. This study also proposes a new scanning strategy to bend borosilicate glass with a thickness of 1 mm and a width of 13 mm directly, and to improve the problem of permanent material accumulation at the bend, with only about 10% increase in thickness at 30° bend angle. Finally, in order to further improve the width of the bendable glass, a simultaneous scanning strategy with dual laser sources was proposed to improve the uneven energy of the bending axis due to the energy decay of laser light propagation in the glass, and a glass width of 25 mm was successfully bent. | en_US |
