Benefits of technology

The patent describes a new type of composite material that has both opaque regions and reinforceable areas within it. This design allows for better strength without adding extra weight or thickness.

Problems solved by technology

This patent describes how strong and rigid optically clear composites can have their own limitations when used with certain types of fibers or other materials. These limitations are caused by factors like the amount of glass needed for optimal results. To improve these properties, another approach would be necessary.

Embodiment Construction

[0006]FIG. 1 is a front view of a composite material in the form of a structural window, illustrating an illustrative reinforcing opaque region pattern in the composite material.

[0007]FIG. 2 is a cross-sectional view of a transparent region and an adjacent opaque region of the structural window.

[0008]FIG. 3 is a front view of another illustrative embodiment of the composite material in the form of a structural window, illustrating an alternative, grid-shaped illustrative reinforcing opaque region pattern in the composite material.

[0009]FIG. 4 is a front view of a structural window which includes a composite material having a central transparent region and an outer opaque region.

[0010]FIG. 5 is an enlarged sectional view, taken along section line 5 in FIG. 4, with reinforcing opaque elements in the opaque region oriented in generally parallel relationship with respect to optically clear elements in the transparent region of the composite material.
