Optically clear strong transparent polymer glass composite

University of Missouri System: Missouri University of Science and Technology
posted on 05/04/2009

A process has been developed whereby glass fibers can be combined with a polymer so as to produce a fiber glass reinforced plastic (FRP) composite which has an optical transparency that is essentially equivalent to that of ordinary window or plate glass. This process does not require any unusual equipment, can be completed in only 30 min., and is adaptable to automated, mass production. Compared to the polymer matrix, the composite has greatly improved mechanical properties; the flexural strength and elastic modulus is increased by 2 to 6 times, the impact strength is increased by up to 10 times, and the work of fracture is up to 5 times larger.

Suggested Uses

  • Security Windows
  • Personal Protective Equipment – faceshields
  • Aerospace Applications – windshields, windows
  • Transparent Armor


  • Optically Clear
  • Strong
  • Lightweight
  • Impact Resistant
  • Easy to Manufacture

Innovation Details

Detailed Description

Optically transparent composite material and process for preparing same: Glass ribbon-reinforced transparent polymer composites which provide excellent optical transparency and a low distortion level over a wide temperature range while exhibiting superior mechanical properties as compared to non-reinforced polymer counterparts, and equivalent properties as compared to glass fiber-reinforced counterparts.
