Die Lithografie ist entscheidend für die Herstellung elektronischer Halbleiter. Neue Lacke (Resiste) mit hoher Sensitivität und Auflösung sind erforderlich, um die Bauteildichte zu erhöhen und die Massenproduktion zu bewältigen. Mit dem Projekt »IndiNaPoly« wollen Fraunhofer-Forschende die chemische Industrie unterstützen, um einen technologischen Vorsprung zu erzielen und neue Märkte erschließen zu können. Resisthersteller sind ein wichtiges Bindeglied in der Halbleiterindustrie. Hersteller von Spezialpolymeren und Halbleiter profitieren ebenfalls von den Ergebnissen.

Fraunhofer researchers have developed a helmet with an integrated acceleration sensor for drivers of construction machinery. The helmet sensors measure the harmful vibrations from the construction machinery that affect the human body. The sensor signals are analyzed and software displays the level of exposure for the wearer. This allows measures to be taken to reduce exposure. A flexible piezo electret film serves as the sensor.

The icing of aircraft wings, especially on the leading edge, impairs aerodynamics and jeopardizes the safety and efficiency of flight operations. Conventional thermal de-icing systems are energy-intensive and incompatible with emission-free aircraft engines. In the EU project “UP-Wing” (Clean Aviation Innovation Program), Fraunhofer LBF is developing an innovative electromechanical de-icing system based on structural dynamic vibrations.

In the RE-IMPACT project, we have developed a non-destructive testing method based on the electromechanical impedance (EMI) method, which can be used to detect structural changes at an early stage and continuously monitor material quality.

Sustainable plastic recyclates and biodegradable polymers for nonwovens and roofing membranes: 1. Is it possible to recycle and additives different waste streams to produce high-quality recyclates, which in turn can be used to produce fibers and films that can be further processed into competitive nonwovens and films for roofing membranes? 2. Can fibers be produced from bio-based polymers that can not only be spun into nonwovens, but whose degradation in the environment can be adjusted and which do not pose a risk to the environment?

The Fraunhofer PREPARE project HATE-Fluor sets new standards in materials development: The goal is to produce fluorine-free elastomers as a sustainable alternative to fluoropolymers – high-performance, durable, and environmentally friendly. The newly developed materials offer maximum chemical and thermal resistance, particularly in sealing technology, for example in hydrogen systems or photovoltaic vacuum systems. Innovative antioxidants and optimized formulations ensure maximum stability – for future-proof solutions without fluorine.

Advances in battery technology for electric mobility: The Accelerated Cell and Battery Testing AccCellBaT project improves virtualization, front-loading, and continuous verification and validation (V&V) in order to optimize battery design, costs, and time to market.

The FNR project “BioFlammschutz” has developed innovative, bio-based, and environmentally friendly phosphorus-containing flame retardants. These are intended to serve as an ecologically and economically advantageous alternative to the halogen-containing flame retardant additives currently in use, which are problematic from an ecotoxicological perspective. The new flame retardants were produced from cotton and wood cellulose and the inexpensive sugar alcohol erythritol using a method developed at Fraunhofer LBF. Their suitability was demonstrated in flame retardant applications for polyolefins and a partially bio-based polyamide.

Components made of zinc die-cast alloys are used in various industries due to their high surface and component quality and the efficiency of the hot-chamber die-casting process. However, they are rarely used for components subject to high cyclic loads because they lack structural durabiity characteristics. To change this, the cyclic material behavior of various zinc die-cast alloys was investigated and summarized in a design concept.
