Popis: Dynamic properties of high strain rate and absorbing energy for laminate composites in the marine environment were studied in this paper. The high strain rate dynamic compressive tests were carried out on Split Hopkinson Pressure Bar(SHPB) experimental facility at strain rate 1800/s, 1530/s, 1230/s and 950/s. The front surface failure modes were Analyzed by optical micrographs. A fractured fibres mode was discussed in high rate compression. The stress-strain rate curves showed that, the specimen dynamic properties were better for the samples immersed in marine environment for 12 days. The energy absorption properties were test by ballistic trajectory experiment. Experimental results and penetration faces showed that, the ballistic trajectory properties with 60days of hygrothermal environment was better.
