When it comes to the characterization of fiber reinforced composites with dynamic measuring techniques many options are available, but they all have pros and cons for different materials and applications. In their paper, Huayamares et al. set out to answer some relevant questions by comparing measurements in 3-point bending and torsion mode. We summarize the main findings of the scientific paper and explain the measurements as well as the corresponding interpretation of the results depending on the use case.
In the previous articles, focusing on thermal analysis under humidity, we have seen that thermogravimetric analysis and dynamic mechanical analysis help determine the influence of water on a material or substance. Thermomechanical analysis complements the analysis under humidity.
Why is water a problem for a part made of thermoplastics? Textbooks describe that the water uptake for some types of polyamide (PA) is really high in both 50% relative humidity and in water. This alone would not be the problem, but the uptake of water leads to very different properties of materials. How can dynamic mechanical analysis (DMA) help with this issue?
As a leading international platform, Tire Technology Expo 2020 featured the latest product launches and innovations from national and international exhibitors and a number of interesting presentations. Quality assurance and environmental compatibility of raw materials, intermediates and end products remain essential in all phases of this process to reach the next milestone for sustainable growth.
Thermoplastic parts can fail. This is no secret. However, when it has happened it is crucial to find out the reason for the failure of a part. Here is a short list of thermal analysis techniques and which questions they can answer in your failure analysis.
Failure of injection-molded thermoplastic parts appear in a wide range of forms. Often, the selected material or the production process of parts and components are the cause of the problem. Whenever faulty parts leave the machine, it is important to find the underlying cause of the failure. We selected two common failures of thermoplastics and show how thermal analysis can help determine the cause of failure.
The flexibility of the DMA GABO EPLEXOR® through its independent drives allows for the realization of a great variety of test conditions from practical applications in a laboratory setting. Dr. Sahbi Aloui explains how you can use the DMA GABO EPLEXOR® to exactly simulate the load situation of a respective application.
Industrial 3D printing processes create functional, end-use parts with mechanically isotropic properties and smooth surface finishes. Read how Prof. Dr. Tim Osswald, Alec Redmann and the team at the University of Wisconsin-Madison worked together with the California-based company Carbon Inc. optimized the thermal curing cycle of EPX 82 resin used in the their Digital Light SynthesisTM (DLSTM) process.
Four technology-driven trends disrupt the automotive industry and transform mobility as we know it today. Our future cars will be autonomous, electric, shared and connected. Polymer parts and components will not become redundant. They will rather be used for different applications. Learn which material properties are crucial in tomorrow’s cars.
The actors in the automotive supply chain are constantly forced to keep up with changing requirements in their industry. Higher fuel efficiency and technological innovations bring about environmental regulations that need to be considered in the design of automotive parts and components. Here, crucial material properties like thermal and mechanical resistance can be determined with thermal analysis.
