Recycling-halogen-free-flame-retardant-plastics

Recycling plastic waste after it has been used takes on special significance as our society becomes increasingly aware of the consequences of CO2-emissions, the growing mountains of waste and at the same time the scarcity of fossil-based raw materials. This also applies to the use of flame retardant plastics which are increasingly equipped with halogen-free flame retardants for environmental reasons.

New-composites-for-durable-engineering-applications-from-used-pet-bottles

Plastic waste and its improper handling lead to global environmental problems. Packaging plastics are a particular problem, because they are disposed of after a short use cycle or released into the environment on landfill sites. One solution to this problem is to turn plastic waste from short lived consumer products into high-quality materials that find new application fields long-lasting technical products. In the ”UpcyclePET” research project, Fraunhofer LBF and EASICOMP GmbH (an expert in long glass fiber reinforced thermoplastics) are developing a new material based on used beverage bottles made of PET (polyethylene terephthalate). Potential target applications are automotive lightweight parts.

New-stabilizers-for-the-long-term-stability-of-polyolefins

Plastics are exposed to high temperatures and mechanical stresses during processing. Without additives, this leads to the degradation of the material and loss of mechanical properties. Scientists at Fraunhofer LBF have developed new bio-based processing stabilizers that can be prepared through simple synthesis methods. They exhibit excellent process stabilizing effects on polyolefins and could replace industrially established petroleum-based stabilizers. In addition, the new antioxidants exhibit low volatility and show no degradation products that are harmful to humans. They are therefore particularly suitable for applications in food processing or pharmaceutical technology.

Nnumerical-lifecycle-simulation-for-composites

Fatigue of components made of continuous fiber reinforced plastics involves a variety of different damage mechanisms. Different types of cracks lead to changes in the local material and component stiffness, which also constantly changes the load distribution in the component over the duration of load-bearing. Current work at Fraunhofer LBF considers the effect of microscopic cracks on the effective stiffness of the composite material in order to take better account of these redistributions in the development of new component design methods.

Optimized injection molding tool facilitates direction-dependent characteristic value determination and reliable component design

An injection molding tool optimized at Fraunhofer LBF facilitates the production of short glass fiber reinforced unidirectional plates for the production of highly oriented specimens under different removal angles. The tool was designed to ensure that the reinforcing fibers are oriented approximately unidirectionally (UD) in the direction of flow. Test specimens for the tensile tests can be removed from the plate at any angle to the flow direction to determine parameters for the material description. This facilitates resource-conserving component design that is suitable for the materials

Temperature-dependent-lifetime-prediction-for-elastomer-components

Elastomers are used in many different application areas, primarily for damping vibrations. Their operating temperature is generally between -50 °C and 150 °C. However, during operation the temperature development depends not only on the ambient temperature, but also to a significant extent on self-heating due to the dissipated energy under cyclical load. The dissipated energy is decisively affected by the material properties. The increases in temperature impact the mechanical behavior and thus the lifetime, and for this reason should be taken into account in the design process. The AiF projects ”Elasto-Opt I and II” were implemented in a partnership between the Technische Universität Darmstadt, Bundeswehr University Munich and Fraunhofer LBF. They focus on capturing and accounting for this temperature dependency in FEM simulation and methods of lifetime analysis. The result is a concept for temperature-dependent lifetime prognosis of elastomer components that is ready for use in applications.

About us

Company portrait

In collaboration with Fraunhofer LBF, companies in the chemical industry, particularly the plastics industry, rely on new, custom-designed plastics or plastic composites, along with the relevant processing technologies, to achieve desired product performance, necessary energy and resource savings or required lightweight design options. All the relevant skills for implementing such and similar requirements are available at Fraunhofer LBF, from chemistry and physics, material sciences and material technology to expertise in analytics, testing and modeling.

Only cutting-edge products with reliable and rapid access to innovative and high-performance materials can be offered competitively on the world market today. Tailored plastics, plastic additives, plastic composites and plastic processing technologies play a central role in meeting high global demands in the areas of mobility, energy, environment, communication, health, nutrition and safety. Plastics enable tremendous savings in resources and energy as well as a wide variety of options in lightweight design.

Particularly when they are fiber-reinforced, particle-filled, foamed or integrated into sandwich structures, plastics can withstand the highest degree of loading and absorb a great deal of energy. They can be supplemented with an additional range of functions such as protection from UV rays and the affects of weathering, reduced fire behavior, functions for the development of special optical properties, electric and thermal conductivity and with sensor and actuator functions.

All components relevant for the implementation of sophisticated plastic applications, running the scope from basic natural science disciplines such as chemistry and physics, material sciences and material technology in processing to expertise in analytics, testing and modeling, are united at a high level under one roof.
