架空夹层玻璃应用的断裂后强度测试

可乐丽发布了一份新的白皮书,为层压工、工程师和建筑师提供了有关架空夹层玻璃结构性能的重要信息,特别是其破碎后性能的信息。

该论文解释了夹层玻璃在顶篷玻璃应用(例如天篷和天窗)中的设计和结构性能如何至关重要,因为它对居住者和维护人员的安全产生重大影响。而且,作为直接结果,夹层玻璃结构的断裂后强度至关重要。

The paper offers a comparison of the mechanical properties of SentryGlas® ionoplast interlayer, PVB and stiff PVB and how each of the materials perform after a breakage, in terms of the environmental conditions and the type of glass used in the lamination, which ultimately determines the breakage pattern. It goes on to analyse the structural behaviour of the different material combinations and their suitability and performance in a variety of overhead applications.

The paper then goes into detail about the two primary test methods deployed to research the phenomenon; one to ascertain immediate post breakage strength against fall through; and another to determine medium-duration post breakage strength over a range of temperatures.

The conclusions of the paper offer a highly useful insight into the relative performance of the different interlayers across different applications, laminate constructions and environmental conditions.
