Predicting the mechanical performance of gears is essential to reducing the time and cost associated with developing new gear applications. We have developed a framework based on experimental case studies, local fiber orientation and intrinsic material behavior that accurately predicts the fatigue lifetime of gears.
Speaking at the ITB Thermal Management Systems & Materials Conference 2024, in Novi, Michigan, Russell Bloomfield, Application Development Manager, presented a session about the performance of proven PPA and PPS materials developed for hybrid and EV thermal management systems, along with findings from chemical exposure tests conducted with dielectric fluids related to immersive cooling.
One way to improve the safety of LiBs is to add SuccinoNitrile (SN), an electrolyte additive, delivering a reduction of harmful gas generation, protecting the cathode and hence reducing the risk of thermal runaway as well as increasing capacity retention of batteries. Join our webinar and learn from our experts how to meet the high safety standards and improve the overall EV battery performance.
Today, PPS is trusted by industry-leading manufacturers and Tier1s worldwide in offering the lowest ion leaching and best strength and toughness retention in hydrolytic environment to ensure fuel cell systems are efficient, have a long life, and are safe and reliable.
Creep is a time dependent deformation process that happens to materials under a certain stress level. However, with proper design and material choices, thermoplastics can be a suitable material for parts with a creep load. Predictability is key when designing load-bearing components. It reduces development time, enables first-time right design and ensures part performance in service. In this Use Case we evaluated an example of creep of a compression limiter. Focusing on the modelling of creep as function of time of injection molded short-glass-fiber-reinforced plastics (SFRP).
Fatigue is concerned with alternating or cyclic loads, even when the load levels are well below the strength of the applied material. Depending on the component, over time such a load will lead to part failure. Based on conducting extensive experiments, we developed a robust framework considering all essential aspects for fatigue. This Use Case focuses on results of our fatigue/lifetime modelling framework for injection molded glass-fiber reinforced plastics, using the example of the load bracket demonstrator.
Ventilator tubing is a bacterial breeding ground, increasing the risk of ventilator acquired pneumonia (VAP). Many patients on ventilators in ICUs suffer from this. Most current breathing circuits are made from non-breathable materials. Thankfully, there is a material that enables permeation of moisture directly out through tubing walls. Envalior’s Arnitel® offers a superior engineering material solution with ultra-high moisture vapor transmission rates.
As radars become more compact in all three dimensions while operating at higher power, thermal management and EMI shielding solutions based on engineering materials solutions become more essential. Envalior offers a complete laser weldable material portfolio for radomes and back covers, ranging from pbt to low dk/df pps up to highly conductive pps compounds. While Envalior continues Xytron innovation, we also leverage the proven properties of Arnite PBT in radar applications.
For gear applications it is key to accurately predict short- and long-term mechanical performance. Applications with different load cases result in a combination of failure modes. One tends to perform dedicated application tests in each design phase. However, with fundamental material knowledge and gear-application know-how one can combine test results obtained via simplified tests, such as standard tensile bar fatigue testing or simplified gear test results, into a model that provides accurate lifetime predictions.
Hydrogen storage is an essential element for the hydrogen driving powertrain of automotive vehicles. There are different storage scenarios for hydrogen that are feasible. Physical storage via adsorption or absorption in solid media might be considered, but also storage of pure hydrogen under cryogenic conditions or storage under high pressure. For automotive storage applications, the industry embraces the last scenario. Hydrogen is stored in high-pressure hydrogen tanks with typical operating pressures of 700 or 350 bars.
