ABSTRACT:
Glass clad/polycarbonate structures that can be fabricated to pass stringent impact resistant tests for hurricane resistant window qualifications and/or be used in security application such as bullet resistant side windows in automobiles. The window structure consists of two layers of glass held together with two sided adhesive tape. The function of the tape is to act as a resin diking system and to control the overall thickness of the glass composite. A polycarbonate film between the glass is held in place by a resinous adhesive. The polycarbonate film is smaller in length and width and essentially floats in the cured resin. Expansion and contraction of the polycarbonate film is not restricted in the highly flexible adhesive. Fatigue adhesion failure and subsequent delamination with time is virtually eliminated.
The framing structure involves mechanically bonding the frame to the window structure via nylon shims. These shims are placed through holes in the frame and glass and fastened to the outside of the frame. With the assistance of metal rollers on the bottom of the frame, the structure can move freely about in the frame. This movement is restricted with sealants. Upon impact the framing structure will absorb some of the energy as well as keeping the window in the frame.
