Lightweight composite components<\/h2>\n\n\n\n

Renewable energies are important sources of electricity in Germany and are considered a central pillar of the energy transition and the decarbonization of electricity generation. The energy transition can be supported by the use of fiber-reinforced lightweight structures. They offer great opportunities in direct electricity storage, as well as indirectly through energy storage using hydrogen as an energy carrier<\/p>\n\n\t<\/div>\n\n<\/div>\n\n<\/div>\n\n\n

Hydrogen will play an important role in energy transformation and future mobility.<\/p>\n\n\n\n

More details<\/a><\/p>\n\n\n\n

Due to the low volumetric energy density, hydrogen has to be stored at high-pressure levels (CGH2), requiring specific containers. Current high-pressure storage systems are made of a thermoplastic liner, wrapped with carbon-epoxy composite. Such tanks are able to store hydrogen at high-pressure levels, safely. Still, these tanks suffer from some limitations such as refueling\/emptying time, weight and volume, durability, robustness and recyclability. Thermoplastic pressure vessels (TPPV\u2019s) are a promising alternative to face these challenges. The laser assisted thermoplastic tape winding process in particular offers great opportunities to increase storage efficiency, as well as reducing variation deviations in quality, due to high quality process control.  In regards to a green footprint, TPPV will enable new routes for recycling of pressure vessels.<\/p>\n\n\n\n

Flywheel storages
 <\/h3>\n\n\n\n

Flywheel accumulators are used to store energy. For example, electrical energy is converted into rotational energy.<\/p>\n\n\n\n

More details<\/a><\/p>\n\n\n\n

The rotational energy that can be stored depends on the square of the rotational speed. This means that high amounts of energy can be stored when the rotational speed of the flywheel accumulator is high. High rotational speeds lead to high centrifugal forces. Carbon fiber reinforced materials with their high specific strength are ideal for counteracting the high centrifugal forces. Thanks to their short response times and high power input capabilities, inertia storage systems are ideal for grid stabilization and energy storage over short periods of time, making them an ideal complement to volatile renewable energy sources such as wind and solar energy.<\/p>\n\n\n\n

Coupling tubes

Wind turbines are generators, which sustainably contribute to the eco-friendly production of electricity, and are also increasingly becoming a key component within the global energy management.<\/p>\n\n\n\n

More details<\/a><\/p>\n\n\n\n

With DYNEXA, the AVANCO Composites has established itself as a strong and reliable provider of composite lightweight design components made of e.g. glass fiber-reinforced plastic (GRP) within the industry. Our high-performance coupling tubes are used in the wind turbine rotor force transmission, and provide the electrical insulation for the generator in case of unplanned voltage surges, as they occur during events such as lightning strikes. We manufacture these high-performance components in large numbers with a consistently high and certified quality. Only the absolute reliability of the coupling will ensure the sustainable yield, and the efficiency of the entire system. The use of particularly low-maintenance lightweight design drives transmissions and components increases the wind power generation efficiency, and significantly helps to establish the wind energy as a lasting competitive source of energy within the energy mix.<\/p>\n\n\n\n

Weight<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

When used intelligently, fiber-reinforced plastics offer the potential to save weight. The aim is to align the fibers to the load conditions and only use them where they are needed. With regard to pressure vessels, these can be locally reinforced using the thermoplastic tape laying process (e.g. in the dome area) and thus save the required amount of fiber material and therefore weight.<\/p>\n\n\n\n

Strength<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

Fiber-reinforced plastics have a high specific strength, which enables them to transfer high loads at a low weight. These high strengths are relevant, for example, for CFRP flywheel accumulators and allow high rotational speeds and therefore high amounts of energy to be stored. Furthermore, the high fiber strengths are used to store hydrogen under high pressure.<\/p>\n\n\n\n

Mass inertia<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

The high specific strength of fiber-reinforced plastics makes it possible to reduce the weight of components and thus also the mass inertia. This is advantageous for pressure vessels in mobility applications, for example.<\/p>\n\n\n\n

Stiffness<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

In addition to their high specific strength, fiber-reinforced plastics are also characterized by their high specific stiffness. This means that deformation under load can be kept to a minimum, which is relevant in fast-rotating systems such as flywheel accumulators or rotor drums, for example, as small gaps between the rotor and stator are possible.<\/p>\n\n\t<\/div>\n\n\n\n

Process stability & control<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

The laser-assisted tape winding process is an in-situ process, i.e. no curing of the component is necessary after the winding process. This reduces production cycle times. Furthermore, the process allows the recording of process-relevant parameters in order to  ensure the quality of the part processed.<\/p>\n\n\n\n

Robustness<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

Thermoplastic composites have very good impact properties. Furthermore, the polymers of the liner and fiber composite matrix can be adapted to each other. This creates a strong bond between the fiber reinforcement and the liner. The liner, which is often a weak point in type 4 tank systems, is thus supported. The boundaries between type 4 and type 5 tank systems become blurred.<\/p>\n\n\n\n

Recyclability & sustainability<\/h3>\n\n\t<\/div>\n\n<\/div>\n\n\n\n

Compared to traditional materials such as steel or aluminium, fibre-reinforced composites cause lower environmental emissions, consume less energy during production and emit fewer greenhouse gases. Low environmental impact and a good carbon footprint make CFRP a genuine material of the future: constructively intelligent and sustainable. Due to the properties of thermoplastic polymers, thermoplastic composites offer very good recycling options compared to thermoset composites. Further benefits:<\/p>\n\n\n\n
