Embodiment Construction

[0021] Referring now to the accompanying drawings, which are shown for purposes of illustrating preferred and various embodiments of the present disclosure, figure 1 Shown in is a block diagram of a system 100 that includes a composite structure 102 and a light source 180 for emitting light 182 toward the composite structure 102 . Composite structure 102 may be composed of a polymer matrix 114 and a plurality of reinforcing fibers 116 embedded in matrix 114 . Fiber 116 may have a fiber index of refraction 200 . The matrix 114 may have a matrix index of refraction 202 . Advantageously, matrix 114 and / or fibers 116 may include photoreactive material 148 that may be sensitive to one or more wavelengths of light 182 that may be emitted by light source 180 to induce a reaction in photoreactive material 148, resulting in matrix 114 changes in the refractive index. In one example, the matrix 114 and / or fiber 116 can include a photosensitive chromophore 150 that can be sensitive to...

Abstract

The name of the invention is high temperature range and high strain range transparent composites based on matrices having optically tunable refractive indices. A system may include a composite structure and a light source. The composite structure may include a matrix having a matrix refractive index, a plurality of fibers embedded in the matrix, and a light-reactive material in the matrix. The light source may be capable of emitting light of an activation wavelength that induces a reaction in the light-reactive material causing a change in the matrix refractive index.

Description

technical field [0001] The present disclosure relates generally to composite materials and, more particularly, to controlling the transparency of fiber-reinforced composite structures. Background technique [0002] Due to its outstanding optical properties, glass is widely used as a transparency in a variety of applications. For example, single sheets of glass are commonly used as glazing materials or as construction materials for buildings. Single panes of glass are also commonly used as transparencies in a variety of vehicular applications. Unfortunately, glass is a relatively dense material and is also relatively brittle such that relatively large thicknesses are required to provide a glass sheet with sufficient strength to resist fracture under load. [0003] Transparencies may also be made from polymeric materials in an attempt to avoid the weight disadvantages associated with single panes of glass. For example, a monolithic sheet can be formed from a clear polymer s...
