2026-08-24 A dataset for the amorphous /microvoid structure and tensile properties of PAN-based carbon fibers doi:10.57760/sciencedb.j00125.0007z en This dataset aims to collect, compare and analyze amorphous/microvoid structural parameters and matched multifilament tensile properties of T and MJ series PAN-based carbon fibers. Synchrotron small-angle X-ray scattering (SAXS) tests are used, with the "Double Debye" model splitting total scattering into amorphous and microvoid components to obtain core parameters including radius of gyration, axial/transverse size ratio, and phase volume ratio. All run-level data are kept unpooled without grade averaging to retain the as-measured scatter of the same grade. The dataset includes raw scattering files, "Double Debye" fitting tables, and standardized processing workflows, providing an empirical benchmark for T/MJ carbon fiber structure-performance comparison, microvoid defect tuning, and structural evolution studies of high-modulus fiber preparation.
