VIRTUAL CHEMICAL EXPOSURE OF COMPOSITE MATERIALS

Unmatched Significance
CheFEM combines chemical exposure thermodynamics (GIM/Sanchez-Lacombe Equation of States) with Finite Element Mechanics (FEM). The calibrated system has a chemical exposure temperature range of 1 Kelvin (!) to polymer matrix melting/decomposition zone and a pressure range of 0 to ≥ 2500 bar.
