Forced entry resistant transparent laminate
A forced entry resistant transparent laminate comprising a combined rigid and energy absorbing laminate panel assembly having a strike side surface opposing a direction of an anticipated threat, bonded together with a transparent, ether-based thermoplastic elastomer interlayer interposed between glass or polymer layers, where the thermoplastic elastomer interlayer further includes a transparent polyurethane having an ultra-high modulus of elasticity. The energy absorbing layers include a transparent, quasi-thermoset cast from an aliphatic urethane bonded to the rigid laminate layers.
1. A forced entry protective laminate comprising a first film;
a first optically clear structure connected to said first film;
a first thermally activated interlayer connected to said first optically clear;
a first energy absorbing layer comprising a pseudo-polymer quasi-thermoset resin;
a second thermally activated interlayer connected to said first energy absorbing layer;
a second optically clear structure connected to said second thermally activated interlayer;
a third thermally activated interlayer connected to said second optically clear structure;
a second energy absorbing layer connected to said third thermally activated interlayer;
a fourth thermally activated interlayer connected to said second energy absorbing layer;
a third optically clear structure connected to said fourth thermally activated interlayer; and
a second film.
2. The forced entry protective laminate of claim 1 , wherein said first optically clear structure is annealed glass.
3. The forced entry protective laminate of claim 2 , wherein said second optically clear structure is annealed glass.
4. The forced entry protective laminate of claim 3 wherein said third optically clear structure is a polycarbonate.
5. The forced entry protective laminate of claim 1 , wherein said first film is an anti-graffiti film.
6. The forced entry protective laminate of claim 1 , wherein said second film is a structural film.
