Property Analysis
The LPWA automatically calculates the A11, A22, D11, and D22 stiffness matrix
   components for the studied material,  rendering strength properties in principle directions.
By accurately measuring bulk and plate wave mode velocities material, the LPWA detects
   small density and  modulus changes in bulk specimens, which can profoundly impact
   structural performance.
By using pulse shape analysis tools which are unique to the LPWA, delaminations
   and debonds in a specimen can be clearly ID'd and located.
Quality Assurance
Material properties can be measured in situ before, during and after performance tests
   such as stress-strain, temperature and fatigue
Laminated composite material properties can be monitored throughout curing process.
Final quality control by verifying expected characteristics and inspecting for damage.
