Exceptional 3D printing method to produce high-performance composites
from AZO Materials
Since ancient civilizations first joined mud and straw together to form bricks, people have fabricated engineered composites of increasing complexity and performance. However, replicating the extraordinary mechanical properties and multifaceted microstructures found in nature has been difficult. Currently, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have showed a novel 3D printing technique that yields exceptional control of the arrangement of short fibers embedded in polymer matrices. They used this additive manufacturing method to program fiber orientation within epoxy composites in specified locations, enabling the formation of structural materials that are enhanced for stiffness, strength and damage tolerance.
