In this study the MMI ConfidentDesign multiscale approach (consisting in a non-linear multiscale simulation based on DIGIMAT registered including the injection modeling of the filled polymer and a multiscale mechanical model using the fiber orientation tensor resulting from the injection) has been combined with an orthotropic damageable elastic simulation. The anisotropic properties (including rupture criterion) are estimated and a multiscale simulation including the heterogeneous material properties issued from injection process is done. The impact of fiber ratios is then investigated. The structural simulation predicts stresses localized close to the punch, as well in injected PA66 than in composite part. Greater the fiber volume ratio, greater the modulus and more brittle the composite.
