Debonding resistant toughened composites prepared by small particle reinforcement of the fiber-matrix interface

摘要

Fiber reinforced composite materials comprising a matrix and reinforcement fibers (10) and further comprising small particles (12) at the fiber-matrix interface provide reinforcement and/or toughening of the fiber-matrix interface without substantial reduction of the core fiber volume fraction in the composite. In another aspect, the present invention provides a method of fabricating a composite material comprising the steps of attaching small particles to a fibrous material, and consolidating the fibrous material into a matrix.
