Solvay Adds Polymer Data to Digimat-MX Database

10 October 2017

Solvay has added data relative to new Amodel polyphthalamide (PPA), Ryton polyphenylene sulphide (PPS) and KetaSpire polyetheretherketone (PEEK) polymer grades to the Digimat-MX database tool of Digimat software from e-Xstream engineering, to store anisotropic measurements and related micromechanical models.

“As a leading innovator in plastic to metal substitution, Solvay offers advanced computer modelling to its customers and is committed to help them effectively simulate the mechanical performance of its materials when designing lightweight fibre-reinforced thermoplastic composite parts,” reports Michel Dubois, Global Technical Expertise Manager for Solvay’s Speciality Polymers Global Business Unit. “The addition of these Solvay grades to the Digimat-MX library signals an important new phase to further support design and simulation experts seeking to replace metal parts with lightweight advanced polymers and composites.”

The Solvay materials added to Digimat-MX are:

  • Three grades of Amodel PPA – AS-4133HS, DW-1140 and DW-1150. The AS-4133HS grade, mainly for automotive applications, is 33% glass fibre reinforced, lubricated and heat stabilised, which allows fast cycle times and mouldability in hot water conditioned moulds. The DW-1140 and DW-1150 grades are approved for potable water contact in the US, France, Germany and the UK. They are respectively 40% and 50% glass fibre reinforced and are designed for high strength and stiffness. They also present good hydrolytic stability and are said to exhibit excellent dimensional stability due to a combination of low water absorption and low coefficient of thermal expansion.
  • Three glass fibre and mineral filled Ryton PPS grades – R7-120, R7-190 and R7-220. In addition, Ryton PPS R-4-200BL has been updated to meet specific customer temperature properties. Solvay’s Ryton PPS family offers a combination of properties including thermal stability, dimensional stability, chemical resistance and inherent flame retardancy.
  • KetaSpire PEEK – KT-880 CF30 – a 30% carbon fibre reinforced grade reported to provide an outstanding level of mechanical performance even at temperatures approaching 300°C and one of the lowest coefficients of thermal expansion. It also offers wear resistance, fatigue resistance and chemical resistance to organics, acids and bases.

Today, all Solvay models provided in Digimat-MX library are mainly dedicated to quasi-static applications at different temperatures (elastoplastic and thermo-elastoplastic models). In response to customer requests Solvay’s Computer-Aided Engineering team identified the need to extend models to high speed impact simulations (up to 100 sec-1). These elasto-viscoplastic models are expected to be added to e-Xstream’s Digimat-MX library soon, as well as other material models for quasi-static applications.
