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:
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.
The SMARTCOMP: Research and Development of Smart Composites Based on the Implementation of Textronic Elements and Functional Materials project aims to develop smart textile structures for use in the manufacture of composites for decoration, interior design, habitats and the creative industries in general.
Chongqing Polycomp International Corp (CPIC) has developed a family of fibreglass products with a flat rather than round cross-section that is said to facilitate higher fibre loading levels and better mechanical properties in injection moulded thermoplastic composites and reduce warpage in thin wall sections.
Plastics converters using the IRONJAW system, which boosts the clamping force of an injection moulding machine, save an average of €10,000 per month and per injection machine, its developer claims.
