Criterion for Selecting Composite Materials for Explosion Containment Structures(Review)

摘要

Experimental data on the dynamic response and strength of simple shells of fiber composites are used to justify the choice of these materials for the load-bearing shells of blast-proof structures.It is shown that in such structures composites are preferred to homogeneous metal alloys(structural steels) to eliminate strong scale effects of an energetic nature.A criterion for selecting fibers is proposed and justified experimentally,and reinforcement patterns are determined to obtain optimal(in the strength-mass ratio) compositions for the load-bearing shells of blast-proof containers and chambers.
