Researchers from the University of Michigan Mechanical Engineering and Architecture Departments have developed a technology that increases the structural performance, strength, and durability of fiber reinforced composite materials. From aerospace to automotive to marine, there is large and increasing demand for high performance fiber composites. The developed technology enables improved composite performance without changing the fiber or matrix materials, only altering the manufacturing process. With an aviation fiber composite market of over $175M, growing at 12.8% CAGR and a marine fiber composite market of over $600M, there is a substantial market for a method to create high performance composites.

Fiber Reinforced Composites

The challenges with existing fiber reinforced composites is providing increased performance without using more expensive materials. In areas such as aerospace the strength and durability per weight are essential, thus improvements in these metrics for the same composite materials is highly desirable. The developed technology will allow for these improvements using any fiber type (e.g. carbon, glass, Kevlar) placed in textile, knitted, or pre-preg layers.
