Abstract

The present invention provides for a resin mixture that comprises a highly structured resin 40 and a less structured resin 50 . The highly structured resin 40 and the less structured resin 50 are mixed to a ratio of between 1:9 and 4:1 by volume, with a more particular ratio of 1:5 to 3:1. The highly structured resin forms ordered micro regions and the ordered micro regions impose order on surrounding less structured resin molecules. The micro regions are essentially groups of the HS resin that will naturally form order structures.

Claims (13)

1. A composite resin mixture comprising:

a highly structured resin comprising highly structured resin molecules;

a less structured resin comprising less structured resin molecules;

wherein said highly structured resin and said less structured resin are mixed to form the composite resin mixture;

wherein the ratio of highly structured resin to less structured resin in the composite resin mixture is from 1:9 to 4:1 by volume;

wherein, within the composite resin mixture, a plurality of the highly structured resin molecules are effective to impose order on a plurality of surrounding less structured resin molecules and to cause the plurality of surrounding less structured resin molecules to adopt an orientation similar to that of the plurality of the highly structured resin molecules, thereby forming ordered micro regions in the composite resin mixture comprising the plurality of the highly structured resin molecules and the plurality of surrounding less structured resin molecules; and

a plurality of cross linking agents effective to covalently bond the plurality of highly structured resin molecules to respective molecules of the plurality of surrounding less structured resin molecules and effective to stabilize the ordered micro regions upon activation of the cross linking agents.

2. The composite resin mixture of claim 1 , wherein said ordered micro regions form continuous matrices within said resin composite mixture.

3. The composite resin mixture of claim 1 , wherein said highly structured resin is a liquid crystal thermoset.

4. The composite resin mixture of claim 1 , wherein said highly structured resin is a polyhedral oligomeric silsesquioxane.

5. The composite resin mixture of claim 1 , wherein said ratio of highly structured resin to said less structured resin is from 1:5 to 3:1 by volume.

6. The resin mixture of claim 1 , wherein the plurality of the highly structured resin molecules are aligned by application of an external field to a degree effective to pull the plurality of surrounding less structured resin molecules into alignment with the plurality of the highly structured resin molecules.

7. An insulating tape impregnated with the composite resin mixture of claim 1 .
