This month’s collection showcases the diverse range of uses for fiber reinforced plastics or composites, spanning from transportation (such as aircraft, automotive, motorcycle) to sustainable energy generation (like wind turbines) and safety applications (such as road barriers).
In addition to traditional injection/compression molding, 3D printing is emerging as a dependable technique for manufacturing composite components. While epoxy resin-based composites continue to be prevalent, alternative resins like polyphenylene sulfide, polyurethane, and polyolefin are also being explored.
Similar to other industries, the concept of circularity is a key focus in the field of composites. Particularly, the emphasis is on recycling these composite structures at the end of their lifespan and repurposing them in the production of new composite parts.

Endless-fibre-reinforced 3d-printing filament and method for the production thereof
Patent number: DE102022115439
Publication date: 2023-12-21
Applicant(s): Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung eingetragener Verein
Inventor(s): WILHELM MICHAEL; ROSENBERG PHILIPP; HENNING FRANK
Summary
The invention relates to a method for producing continuous-fiber-reinforced 3D printing filaments comprising a thermoplastic matrix polymer with a plurality of continuous fibers extending in the longitudinal direction of the 3D printing filament. According to said method, a plurality of continuous fibers are oriented according to the arrangement thereof in the 3D printing filament and are impregnated with the thermoplastic matrix polymer. The continuous strand thus obtained is then cut into lengths to form the continuous-fiber-reinforced 3D printing filament. According to the invention, the plurality of aligned continuous fibers is impregnated with a liquid reaction mixture which contains a liquid monomer, di- and/or oligomer suitable for polymerization to form the thermoplastic matrix polymer and an initiator and/or catalyst suitable for initiating the polymerization. The monomer, di- and/or oligomer is then polymerized in situ to form the matrix polymer. The invention further relates to a continuous fiber-reinforced 3D printing filament produced in this way.
