Stereocomplex PLA for composites
1st June 2021
Researchers at the Fraunhofer Institute for Applied Polymer Research (IAP), based in Potsdam, Germany, have received funding to develop new reinforcing PLA fibres for composites.
The challenge is that conventional PLA has a relatively low temperature resistance and technical fibres can be produced most economically using the melt spinning process.
The Fraunhofer IAP team has developed more thermally stable stereocomplex PLA (sc-PLA), in which the PLA molecules form a special crystal structure. This allows the production of fibres which have a melting point that is 40-50°C higher than conventional PLA fibres.
The researchers are now working with fibre producer Trevia to optimise a melt spinning process for sc-PLA filament yarns.
The Hydrogen Stream: More hydrogen for the ports of Rotterdam and Antwerp
Australia and Chile are both granting funds to green hydrogen projects and Denmark is exempting pilot power-to-gas projects from complying with its energy legislation. Furthermore, the Fraunhofer Institute for Applied Polymer Research IAP is working to find solutions for private customers to produce hydrogen.French industrial gas company Air Liquide, Belgian compressed natural gas supplier DATS 24 and the Port of Antwerp are working to deploy 300 hydrogen-powered trucks and the related renewable hydrogen production infrastructure in Belgium as part of the HyTrucks initiative. This project aims .

Starship nails the landing
A prototype of SpaceX’s Starship rocket finally stuck the landing after another high-altitude flight test. The SN15 craft touched down softly following the six-minute flight, which reached 10km altitude and included a number of manoeuvres. Four previous prototypes had exploded following flights.
