Multi-layer matrix composite having improved energy absorption, dissipation and shock wave mitigation capabilities

摘要

The disclosure relates to matrix composites comprising high strain-rate sensitive elastomers in a multi-layer construct which provide ballistic-resistant material systems with enhanced protection against blast damage as well as ballistic impact. According to one embodiment, a matrix composite for impact resistance and blast mitigation formed in a multi-layer configuration may include: (a) one or more outer layers comprising poly(urethane urea) having a strain-rate sensitivity characteristic in the range of 1,000/sec to 1,000,000/sec; and (b) one or more inner layers comprising poly(urethane urea) having a strain-rate sensitivity characteristic in the range of 10,000/sec to 1,000,000/sec.
