Multiple function, self-repairing composites with special adhesives
First Claim
1. A method of making a composite comprising:
- placing a porous conduit on a first layer,placing a second layer on top of a porous conduit, wherein the first and second lavers comprise fibers;
transferring a curable resin through the porous conduit and through the layers, the transferring comprising applying a pressure of from 0 psi to 10,000 psi;
voiding the porous conduit after the transferring; and
allowing the curable resin to harden to form a matrix, wherein the voided porous conduit is a tube positioned in the matrix.

Abstract
A system for self-repairing matrices such as concrete or cementitous matrices, polymeric matrices, and/or fibrous matrices, including laminates thereof The system includes repair agents retained in and/or on vessels, such as hollow fibers, within the matrix. Upon impact, the vessel rupture, releasing the chemicals. For multi-layer laminates, the systems provides a total dynamic energetic circulation system that functions as an in situ fluidic system in at least one layer or area. The energy from the impact ruptures the vessels to release the chemical(s), and mixes the chemical(s) and pushes the chemical(s) and/or resulting compound through the matrix. The repair agents can withstand high temperatures, such as the heat of processing of many laminates, e.g., 250-350° F.
