Composites infusion simulation accounting for mechanical deformation

Click to view webinar recording

Mechanical deformation of the preform might occur during resin injection, in processes such as Vacuum Assisted Resin Infusion (VARI), Compression-RTM (C-RTM), High Pressure RTM (HP-RTM) …. This deformation created by the resin pressure, locally modifies the properties of the preform (fiber content, thickness, permeability) and, as a consequence, affects how the resin will flow. It is thus important to capture this deformation to accurately simulate the process and predict associated manufacturing defects.

This behavior is captured thanks to a fluid-mechanics coupled simulation that will be described and demonstrated during this webinar.

This new capability was released in December 2016 version of PAM-COMPOSITES.
