Claims
- 1. A window for a motor vehicle comprising transparent polycarbonate plastic material and reinforcement particles dispersed within the polycarbonate plastic material, said reinforcement particles comprise less than about 10% of a total volume of the window, at least 50% of the reinforcement particles having a thickness of less than about 10 nanometers, said reinforcement particles being selected and configured such that the window has a transmittance of visible light which is at least 95% of the transmittance of visible light that would exist through the window in the absence of the reinforcement particles, said reinforcement particles comprising one or more mineral platelet layers.
- 2. A window according to claim 1, wherein at least 70% of the particles have a thickness of less than about 5 nanometers.
- 3. A window according to claim 2, wherein at least 99% of the particles have a thickness of less than about 30 nanometers.
- 4. A window according to claim 3, wherein at least 80% of the particles have an aspect ratio of between about 50 to about 300.
- 5. A window according to claim 4, wherein at least 90% of the particles have an aspect ratio of between about 100 to about 200.
- 6. A window according to claim 3, wherein said particles are of a material selected from a group consisting of montmorillonite, vermiculite, hectorite, saponite, hydrotalcites, kanemite, sodium octosilicate, magadiite, and keyaite.
- 7. A window comprising a transparent thermoplastic material selected from the group consisting of polycarbonate and acrylic, and reinforcement particles dispersed within the thermoplastic material, the reinforcement particles comprise less than 10% of a total volume of the window, at least 50% of the reinforcement particles have a thickness of less than 10 nanometers, the reinforcement particles selected and configured such that the window has a transmittance of visible light which is at least 95% of the transmittance of visible light that would exist through the window in the absence of the reinforcement particles, said reinforcement particles comprising one or more mineral platelet layers.
- 8. A window according to claim 7, wherein at least 70% of the particles have a thickness of less than about 5 nanometers.
- 9. A window according to claim 8, wherein at least 99% of the particles have a thickness of less than about 30 nanometers.
- 10. A window according to claim 9, wherein at least 80% of the particles have an aspect ratio of between about 50 to about 300.
- 11. A window according to claim 10, wherein at least 90% of the particles have an aspect ratio of between about 100 to about 200.
- 12. A window according to claim 9, wherein said particles are of a material selected from a group consisting of montmorillonite, vermiculite, hectorite, saponite, hydrotalcites, kanemite, sodium octosilicate, magadiite, and kenyaite.
