As demand increases, the amount of CFRP waste, either from production or at the end of life of components, increases simultaneously and sustainable solutions such as disposal, reuse or recycling of fiber reinforced materials getting more and more important. In this paper one possibility for recycling short carbon fiber reinforced polyamide 6.6 (CF/PA 6.6) is presented. The recycling process includes shredding of the material, drying and filament extrusion to enable a reuse of the material with an additive manufacturing process. The focus of this investigation is on the mechanical properties of the recycled filaments itself as well as on the 3D printed specimen considered recycled filaments. The properties at different stages of the short carbon fiber reinforced polyamide 6.6 recycling process were investigated, including the juvenile CF/PA 6.6 as well as specimens made from one- or two-times recycled material. Mechanical performance was evaluated by tensile, bending and impact testing. Experimental results pointed out that no significant difference in performance of juvenile and recycled materials was observed for tensile and flexural loads. The impact strength of the recycled specimen decreased to a small extent.}, language = {en} } @article{MorbitzerSchukraftLohretal.2023, author = {Morbitzer, Philipp Christopher and Schukraft, Jo{\´e}l and Lohr, Christoph and Weidenmann, Kay Andr{\´e}}, title = {In-situ SEM investigation on the damage behavior of an interpenetrating metal ceramic composite}, volume = {2023}, pages = {117278}, journal = {Composite Structures}, number = {321}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0263-8223}, doi = {https://doi.org/10.1016/j.compstruct.2023.117278}, year = {2023}, language = {en} } @article{SchukraftLohrWeidenmann2023, author = {Schukraft, Jo{\´e}l and Lohr, Christoph and Weidenmann, Kay Andr{\´e}}, title = {Approaches to X-ray CT Evaluation of In-Situ Experiments on Damage Evolution in an Interpenetrating Metal-Ceramic Composite with Residual Porosity}, volume = {30}, journal = {Applied Composite Materials}, number = {3}, publisher = {Springer}, address = {Dordrecht}, issn = {0929-189X}, doi = {https://doi.org/10.1007/s10443-023-10115-x}, pages = {815 -- 831}, year = {2023}, abstract = {An interpenetrating metal-ceramic composite of AlSi10Mg and an open porous alumina foam, with residual porosity is investigated for the material damage under compressive load within an X-ray CT in-situ load stage. The focus of the research is on damage detection and evaluation with the commercial Avizo® software by ThermoFisher Scientific. Four different approaches are used to detect the material damage and compared afterward on their efficiency in detecting the material damage volume but not the porosity within the material. Image Stack Processing combined with different filtering techniques, as well as Digital Volume Correlation is used in this work to separate the material porosity and the material damage. For the here investigated material system with mainly spherical pores, a geometrical filter was very successful to separate porosity and damage. Nevertheless, the Digital Volume Correlation based approach showed many advantages in damage detection and turned out to be the approach of choice regarding damage onset.}, language = {en} }
