VAP® infusion-moulded carbon fibre spar caps
PAN-based carbon fibres with a high carbonization degree (>99%) and their industrial production process were first developed in the 1960s.
Fire-retardant Composite Panel for Shipbuilding
Fiber-reinforced composite materials are rarely used in cruise or merchant ships for fire safety reasons. Saertex has now developed a fire-retardant standard panel and worked additionaly with the Meyer Group to incorporate the composite into a sandwich construction for the sun deck and exterior walls of a river cruise ship, achieving a 45 % weight saving.
INDUSTRIALIZED MANUFACTURING OF CFRP REINFORCEMENT PROFILES
The current method of manufacturing composite structures, especially in aviation, is characterized by a variety of manual and semi-automated production processes. In order to satisfy the demand for an increased production rate in a manner that conserves resources and is cost-effective, while also taking into account a wide range of variants, novel automated technologies for the production of frames have been developed during the KOLIPRI project.
Alternatives to balsa wood in wind turbine blades
Sandwich structures made using balsa wood have been used in composite structures worldwide for more than 40 years. The aim of a core is to distribute stress and loads from one skin across the thickness to the other. Compared to laminates with balsa, sandwich structures with SAERfoam generally show superior performance with a reduced weight.
Large-scale preforming – innovative approach in the production of rotor blades
In order to meet the demand for shorter cycle times and higher quality demands of the growing fiber-plastic composite parts (FRP), the Institut für integrierte Produktentwicklung (BIK) of the University of Bremen, the producer of non-crimp fabrics, the SAERTEX GmbH & Co. KG and the rotor blade manufacturer AREVA Blades GmbH developed new manufacturing technologies and automation-enabled materials.
Fire retardant fiber-reinforced components according to DIN SPEC 91326
Using examples, DIN SPEC 91326 describes various FRP structures with tested fire-protection properties according to DIN EN 45545 and known mechanical properties.
