Cover Story: The performance of thermoplastic matrix composites for linerless Type V cryotanks is evaluated using a partially coupled multiscale computational framework to assess matrix selection under realistic conditions. Previously published atomistic molecular dynamics simulations provide temperature-dependent stiffness, thermal expansion, and yield strength for six neat thermoplastics. These inputs feed a micromechanics model simulating cooldown to liquid hydrogen temperature followed by biaxial loading representative of cylindrical tank acreage. Progressive damage analyses predict matrix microcracking and burst behavior for four layups. The results show that [55/5/−55/−5] Double–Double and [0/±30/±60]s layups with low-melt PAEK or PEKK matrices offer superior microcrack resistance, demonstrating the framework’s value for guiding material and layup selection.
