Herausforderungen bei der Etablierung einer Circular Economy von carbonfaservertärkten Kunststoffen (CFK) ergeben sich insbesondere durch die nötige, jedoch problematische Trennung des Faser‐Matrix‐Verbunds. Das Pyrolyseverfahren stellt eine mögliche, bereits industriell umgesetzte, Technologie zur Verbundtrennung dar. Eine Weiterentwicklung ist die mikrowellenunterstütze Pyrolyse, bei der das CFK‐Material durch die Mikrowellen aufgeheizt und so die Faser freigelegt wird. Prozessgrundlagen und Einflüsse auf die Faser‐Matrix‐Trennung werden im vorliegenden Beitrag betrachtet.

The recycling of Carbon Fibers Reinforced Plastics (CFRP) wastes is becoming increasingly important in the aerospace industry. For most of the technologies, the recycled CF (rCF) are discontinuous, misaligned and unsized. Compared to thermal treatments, the orientation, the length and the brittleness of the rCF are better preserved with the SuperCritical Water Solvolysis (SCWS). The effect of the sizing removal on the recycled CFRP behavior is studied by conducting static characterizations. Realigned virgin CF were used to manufacture sample plates which underwent short beam shear tests. An environmental assessment was carried out on the CFRP end-of-life with a focus on SCWS.

“…Measurements of the tensile strength and modulus of elasticity were performed using a Universal Testing machine Monsanto trademark and according to ASTM E8-1998 for tension testing (Nguyen and Kubouchi 2012). This assay was performed on specimens of 2 inches (0.05 m) long for each of the three materials, both before and after making contact with the aqueous solution of MEA at 30 % weight at a test speed of 5 mm/min, capacity from 0 to 10,000 MPa, and ambient temperature of 25°C.…”

The burning of combustible material that produces emissions released to the atmosphere results in unfavorable climate change due to emissions of CO 2 , NO x , and acid rain by SO x , endangering the health of the population. The treatment of combustion gases by means of a packed absorption column with a high-efficiency liquidgas contactor material reduces pollutant emissions to the atmosphere, where combustion gases make contact with aqueous amine solution of mono ethanol amine (MEA), using different structured packing materials which can be metallic, polymeric, or ceramic. The objective of this work is to study which one of these three types of materials of gas-liquid contactors presents the lowest deterioration in the presence of combustion gases flowing countercurrent to MEA. The materials were evaluated according to the Standard Test Methods ASTM G31-2004 for corrosion testing, ASTM E8-1998 for tension testing, ASTM E384-1990 for microhardness testing, ASTM G5-1999 for potentiodynamic and potentiostatic testing, and the procedure of NRF-194 PEMEX-2007. The properties studied were the tensile strengths, the hardness values, and the elastic moduli, before and after structured packing materials made contact with combustion gases in MEA aqueous solution. The results showed that in acidic and basic mediums, the metallic material was the most resistant to abrasion; it has the highest tensile strength, and presents more resistance during the stress test. The hardness results for the materials were metallic: 190 KH, polymeric: 20 KH, and ceramic: 700KH. The respective corrosion resistances in the presence of MEA were 1.63 9 10 -3 , 3.76 9 10 -3 , and 1.42 9 10 -2 mm/year.
