Abstract
Construction materials containing surface modified reinforcements are used to fabricate composite structures. The composite structures comprise a matrix material and surface modified reinforcements, such as fibers and particulates. The surface modifier may be applied to a fiber surface using conventional sizing equipment and provides a durable film on the fiber. The surface modifier may be selected to have multifunctional properties, for example, increasing fiber pull-out strength, imparting bio-active properties, improving moisture resistance and other desirable properties to the composite structure.
Claims55
A composite structure comprising:
- a matrix material;
- and
- surface-modified reinforcements distributed in at least a portion of the matrix material wherein the reinforcements are surface-modified by multifunctional molecules having a plurality of functions and one of the functions is to anchor the molecules to one of the reinforcement and the matrix.
