Experimental Simulation of Dynamic Compression Properties of CFRP Cylinders under High Launch Overload

Abstract Abstract.To explore the mechanical behavior of carbon fiber reinforced plastics (CFRP) under high launch overload, this study presents a laboratory loading technological method for chamber-pressure curve simulation overload using Φ100 mm-diameter split-Hopkinson pressure bar (SHPB) device. On basis, experiments are carried out to dynamic compression properties and failure modes CFRP cylinders. The results show that applying load changing in similar way chamber pressure-temperature (P-T) specimens large-diameter SHPB device is an effective technical means simulate evolution cylinders overload. Through testing simulation, it found cylindrical members have compressive strength 611 MPa, maximum force weight 893 kN 9023 g respectively, strain between 0.5% 0.6%. As structural member, exhibit rigidity good resistance
