| Objective To investigate effects of vacuum aging on properties and structure of X2101 bismaleimide (BMI) matrix composites. Methods The X2101 BMI matrix composites were suffered from a high-temperature and vacuum aging in a tube furnace at 330 ℃, 350 ℃, 370 ℃ and 400 ℃. Effects of aging conditions on mass loss ratio, chemical structure, storage modulus and mechanical properties were investigated by weighing method, Fourier infrared (FTIR) spectrometer, dynamic mechanical analyzer (DMA) and universal test machine. Results The maximum mass loss ratio of composites was lower than 4%; thermal aging below 350 ℃ had almost no influence on the chemical structure of matrix resin; the storage modulus firstly increased and then decreased with the increase of aging temperature; the retention ratio of mechanical properties of composites thermally aged at 350 ℃ was above 65%. Conclusion X2101 BMI Matrix Composites is a kind of high-temperature resistant structural material with excellent performance, and can be used to manufacture aerospace structural components servicing at300 ℃. |
