Plastic laminates and methods for making the same
View Patent ↗In one embodiment, a laminate comprises: a plastic sheet, a second sheet, an adhesive disposed between and in physical contact with the plastic sheet and the second sheet, and an interlayer formed from a liquid filling having a viscosity that does not form bubbles visible to the unaided eye. The laminate has a storage modulus that varies by a factor less than or equal to about 200 at 1 Hz in the temperature range of −40° C. to 200° C. In another embodiment, a laminate comprises: a plastic sheet, a second sheet, an adhesive disposed between and in physical contact with the plastic sheet and the second sheet, and an elastomer interlayer formed from a liquid RTV filling. In one embodiment, a method for making a laminate comprises: adhering a glass sheet to a plastic sheet with an adhesive to form a gap therebetween, and introducing a liquid RTV filling to the gap.

5. The laminate of claim 1 , wherein the adhesive comprises an acrylic foam tape.
6. The laminate of claim 1 , wherein the interlayer is disposed in the gap between the plastic sheet first surface and the second sheet second surface, and wherein the adhesive substantially surrounds the gap.
7. The laminate of claim 1 , wherein the interlayer fills the gap between the plastic sheet first surface and the second sheet second surface.
8. The laminate of claim 1 , wherein there are no bubbles visible to the unaided eye in the interlayer.
9. A laminate, comprising:
a plastic sheet having a plastic sheet first surface;
a second sheet having a second sheet second surface, wherein the second sheet comprises plastic or glass;
an adhesive disposed between and in physical contact with the plastic sheet first surface and the second sheet second surface, wherein the adhesive forms a gap between the plastic sheet first surface and the second sheet second surface; and
an elastomer interlayer formed from a liquid room temperature vulcanize filling that is cured;
wherein the elastomer interlayer is located between and in physical contact with the plastic sheet first surface and the second sheet second surface.
10. The laminate of claim 9 , wherein the elastomer interlayer further comprises a storage modulus that varies by a factor of less than or equal to about 500 at 1 Hz in the temperature range of −40° C. to 200° C.
11. The laminate of claim 9 , wherein the liquid room temperature vulcanize filling comprises silicone room temperature vulcanize.

14. The laminate of claim 9 , wherein there are no bubbles visible to the unaided eye in the interlayer.
15. A laminate, comprising:
a thermoplastic sheet having a thermoplastic sheet first surface;
a glass sheet having a glass sheet second surface;
an acrylic foam disposed between and in physical contact with the thermoplastic sheet first surface and the glass sheet second surface, wherein the acrylic foam forms a gap between the thermoplastic sheet first surface and the glass sheet second surface; and
an elastomer interlayer formed from a silicone room temperature vulcanize filling that is cured, wherein the elastomer interlayer is located between and in physical contact with the glass sheet second surface and the thermoplastic sheet first surface.
16. The laminate of claim 15 , wherein the acrylic foam is disposed around the elastomeric interlayer.
17. The laminate of claim 15 , wherein the elastomeric interlayer fills the gap.
18. A method for making a laminate, comprising:
