Goal is to design a transportation tank that does not exceed 4 bars (relative) within 10 h, starting at atmospheric pressure. PUR-foam is a suitable material for the insulation. A 12,5 l small scale tank prototype reached 4 bar (relative) within 87 minutes, which is, regarding the influence of the size, a satisfying result. The mechanical properties change significantly at cryogenic temperatures. The bending modulus is similar at first, but decreases at a certain point by appr. 50 %. However, the maximum stress is much higher and could not be reached within this testing setup. }, keywords = {Glass fiber reinforced polymer,cryogenic liquids,liquefied natural gas,transportation tanks}, url = {https://aml.iaamonline.org/article_13910.html}, eprint = {https://aml.iaamonline.org/article_13910_a5d648a70a05e8f30ee005ec1532ddf5.pdf} }
