Digimat for long fibre reinforced materials Advanced simulation captures part performance for fibre reinforced thermoplastics Comparing the results of isotropic material data to anisotropic material data Case study https://hexagon.com/ Figure 2: Digimat material model workflow when coupled with an FEA solver Manufacturing Intelligence hexagonmi.com2 Solution Avient leveraged Digimat to reverse-engineer material data based on the microstructure, tensile test data, and micro-mechanical modelling. Avient and Hexagon used Digimat to develop anisotropic long fibre material data for a molded connector rod. We are putting data to work to boost efficiency, productivity, quality and safety across industrial, manufacturing, infrastructure, public sector, and mobility applications.

You can trust that Avient materials meet the rigorous quality and safety management standards required across the globe You can be certain that Avient meets or exceeds the material safety data reporting requirements of your country or region

In order to meet demand and avoid delays, multiple PCR sourcing outlets are often necessary and multi-pass recycling is utilized, both of which can increase the risk of polymer degradation impacting mechanical properties and creating potential product safety issues due to food contact concerns. Convertors and brand owners need to make educated choices for their recycled materials based on formulation expertise and data science to help achieve a consistent packaging product. Based on color science, the tool helps optimize the ratio of virgin resin to PCR in order to achieve the best acceptable rendering, proven by scientific data.
