The Materials Characterization Lab

Researchers at the Advanced Structures and Composites Center have the ability to probe the internal structure and properties of materials.  This allows forunderstanding of the fundamental properties of the material from the nano to macro scale. Technical capabilities include computer analysis, advanced visualization, and multiscale microscopy.  Equipment in the Materials Characterization Lab includes:

 
Atomic Force Microscope

afm.jpgThe AFM is used to take measurements of wood, fiber and wood polymer surface properties from micron scale down to nano-scale including long z-scan range above 25 microns to account for the microscope roughness of wood cellular structure.

 
X-Ray Microtomography

Dynamic Mechanical Thermal Analyzer

Used to determine physical material properties through tension, compression, three-point-bending, shear, and single- and dual-cantilever testing
 
Thermogravimetric Analyzer
