searching for the poisson's ratio or shear modulus of resin
(OP)
I would like to know what is approximatively the poisson's ratio or shear modulus of resin (epoxy or cyanate ester)
Thank you in advance.

RE: searching for the poisson's ratio or shear modulus of resin
But, as an approximation for Poisson's Ratio, try something around 0.33 for the neat resins, but between 0.19 and 0.34 for fiber reinforced composites.
The shear modulus, Poisson's ratio, and Young's Modulus should be related by the standard equation; but remember the Modulus of elasticity of a polymer is time dependent (and most reported measurements are based on the smount of deformation that occurs at a given stress over 10 seconds.)
