Modelling and predicting the durability of reinforced plastic components is highly complex and challenging. This is why e-Xstream engineering and DSM have decided to join forces and combine their efforts to enable use of a new methodology and workflow within the Digimat platform. The combination of DSM’s high-performance thermoplastic solution and modelling approach of fatigue failure mechanisms, and e-Xstream’s accurate and convenient numerical tools, will give users the opportunity to access an improved fatigue modeling methodology within Digimat. The approach has been developed and validated on DSM grades to empower durability prediction of reinforced plastic components.
«Assessing the lifetime of reinforced plastic component by simulation is challenging, but we do believe thanks to this cooperation with DSM to be able to reduce design lead time with reliable workflow and results. DSM material users will benefit from a material database combined with a validated methodology and a dedicated fatigue post-processing tool within Digimat.» said Guillaume Boisot, Business Development Manager at e-Xstream engineering.
Within this partnership, DSM has added two grades in Digimat-MX:
- The Akulon S223-HG0, a 50% glass reinforced and heat stabilized PA66 material that is used by its customers in applications ranging from automotive, electronics & electrical, to furniture and packaging. In molded parts, the material offers a good balance of easy design and processing with outstanding mechanical properties over a wide temperature range and in diverse conditions.
- The ForTii Ace MX53T, a 50% glass reinforced and breakthrough high temperature PPA for demanding structural applications in various industries, such as aluminum die-cast replacement of enclosures (EPS, actuators, sensors), brackets and covers in the automotive industry. This grade has an extreme chemical resistance, suitable for applications that need high mechanics at elevated temperatures. ForTii Ace MX53T enables an extreme robust part performance over a temperature range from -35°C up to 150°C.
“The automotive industry is looking for light weighting opportunities for various reasons, like; function integration, NVH optimization, cost optimization and light weighting to reduce CO2 emissions, build in safety and infotainment systems or increase driving range for battery driven vehicles. Another trend is that designers and engineers are facing shorter design cycles, meaning that computer-based designs, predictability of part performance and 3D prototyping are key for metal replacement programs.” said Tim Vorage, DSM Global Market Development Manager ForTii PA4T.
“The close cooperation with e- Xstream is addressing these key needs from the market and allows us to bring predictability of part performance directly to our industry partners with innovative engineering plastics such as ForTii Ace MX53T (PA4T GF50).”
The Akulon S223-HG0 and ForTii Ace MX53T which are used in injection modeling will be available for high cycle fatigue analysis. Customers will be free to handle the main DSM grades to obtain the structural design and characteristics they want.
