Abstract (English):
Dynamics of impact damage and friction of fire-resistant polymer composite matrix from polyphenylene sulfide reinforced by carbon fabric was studying by nanosecond resolution fluorescence spectroscopy and acoustic emission study It was found that microcracks are formed in moments at the nodes of a shock wave running through the sample. Crazing includes several following stages: carbon fiber breaks during less than 10 ns, the filaments of them doing for about 4 μs and carbon fabric during about 15-20 μs.
