Composite Mechanics
Research & Development
Composite Mechanics
The CMRL studies composite mechanics with experimental testing and observation through micromechanical failure mechanisms as well as computational analysis. The Laboratory studies and replicates the mechanics of resin development creating new prepreg design concepts. These studies allow the design of new resin and prepreg systems meeting future needs for our customers.
Mechanics research activities include:
- Micromechanics of composite/neat resin including experimental mechanics and computational analysis
- Study on Prepreg permeability for OOA cure material systems
Equipment and analysis tools:
- Mechanical testing frame
- Finite Element Method (FEM)
- Digital Image Correlation(2D/3D DIC)

Resin Compression Test - Preparation of Cylindrical coupon investigating
resin compression failure mechanism

Digital Image Correlation Setup - 2D DIC capturing edge/displacements/
3D DIC capturing in-place displacements
V-Notch Test – DIC measurement: Shear strain
Center-notched Tension Test - Opening displacement/Sliding displacement
obtained from DIC
Microscopy of OHC Specimen – Identification of OHC failure mechanism (Kink-band in the 0deg layer)
FEM Analysis –
Crack propagation simulated using
Progressive First Ply Failure (PFPF)
