The invention relates to the technical field of glass forming, and particularly provides metal fiber cloth for glass forming weakening, a manufacturing method for glass forming weakening by using the metal fiber cloth and laminated glass. The metal fiber cloth comprises a forming protection area and a forming weakening area, the forming protection area is in direct contact with the surface of the softened glass plate and does not damage the surface, and the forming weakening area is in direct contact with the surface of the softened glass plate and forms a microcrack area on the surface. According to the laminated glass, the surface optical quality of the central area of the laminated glass can be guaranteed, the safety strength requirement for protecting passengers in an automobile when the laminated glass is used as automobile glass is met, the surface impact strength of the glass can be obviously reduced, the HIC value of the laminated glass is smaller than 1000, and the service life of the laminated glass is prolonged. The impact strength at the stage that the head of a pedestrian collides with the outer glass and is broken when the pedestrian collides with the laminated glass can be obviously reduced, and the safety of the pedestrian can be protected to the greatest extent.
本申请涉及玻璃成型技术领域,具体地提供一种用于玻璃成型弱化的金属纤维布,以及使用该金属纤维布进行玻璃成型弱化的制造方法和夹层玻璃。所述金属纤维布包括成型保护区和成型弱化区,成型保护区与软化的玻璃板的表面直接接触且不破坏所述表面,成型弱化区与软化的玻璃板的表面直接接触且在所述表面上形成微裂纹区域。本申请既能够保证夹层玻璃的中央区域的表面光学质量,以及满足作为汽车玻璃使用时保护车内乘客的安全强度要求,又能够明显地降低玻璃表面冲击强度,使夹层玻璃的HIC值小于1000,能够显著降低行人与夹层玻璃发生碰撞时在其头部与外片玻璃碰撞并破碎的阶段的冲击强度,有利于最大程度地保护行人的安全。
