A manufacturing method of bullet-proof glass is provided to improve the bullet-proof performance economically by multi-laminating high clear polycarbonate material having strong impact resistance and high clear polyester film having excellent tensile strength. A manufacturing method of bullet-proof glass, which has multi-layered glass consisting of at least two pieces of glass such as flat glass and curved glass in order to keep the glass from the penetration of fragments from guns' warhead or strong explosive, comprises combining multi-layer film layers(90a,90b) consisting of high clear polycarbonate film layer of which thickness is at least 50-600mum and high clear polyester film layer of which thickness is at least 50-500mum on the polycarbonate film layer in the space between the normal glass parts(10a,10b,10c) and another normal glass part, and placing polyvinyl butyral film of which thickness is 380-1,500mum having excellent adhesiveness on the both faces(30a,30b,30c,30d) of the multi-layer film. |
