主　　题：Bamboo scrimber carbon fiber reinforced polymer(CFRP) flexural performance adhesive debonding 

摘      要：This study presents a new structure made up of bamboo scrimber and carbon fiber reinforced polymer(CFRP)to address the low stiffness and strength of bamboo ***-point bending test and finite element model were conducted to study the failure mode,strain-displacement relationship,load-displacement relationship and relationships between strain distribution,contact pressure and deflection,and adhesive *** results indicated that the flexural modulus and static flexural strength of the composite beams were effectively increased thanks to the CFRP *** flexural modulus of the composite specimens were 2.33-2.94 times that of bamboo scrimber beams,and the flexural strength were 1.49-1.58 times that of bamboo scrimber *** debonding had a great influence on the strain distribution and deflection of the composite *** was an important factor for the failure of the CFRP-bamboo scrimber composite *** to the finite element simulation,the strain distribution,contact pressure and deflection also greatly changed with the adhesive *** complete peeling,the deflection of the specimen was 3.09 times that of the unpeeled because it was no longer an integral beam.
