thread334-177933: Young's Modulus from DMA Data?

Dear all

We are currently in a research project of enchancing thiol-ene composites strenght. However with respect to what is noted in the previous thread, DMTA is not specifically used for obtaining E-moldulus (young's modulus) of a material, though it should give a close result to the actual value. in several performs to obtain this for pure thio-ene, an E-modulus of 9 GPa is given by DMTA while according to literatures, it should be around 1. caliberation has been double checked but such deviation from the actual value is completely unexpected. I would appreciate it if anyone could shed some light on this.
