Fabrication and optical/thermal properties of glass particle-epoxy optically transparent composites

摘要

The possibility of fabricating a new type of optically transparent glass particle dispersed epoxy matrix composite by tailoring the refractive index of the particle and matrix was studied. Glass particles with an average diameter of ≈8μm were incorporated into a clear epoxy matrix and the par- ticle volume fraction ranged from 0.01 to 0.17. The refractive index difference after fabrication was less than 10~-3. The light transmittance of the composite in UV-visible region and the coefficient of ther- mal expansion(CTE) of the composite were measured.
