ABSTRACT = {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 scrimbers. Three-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 debonding. The results indicated
that the flexural modulus and static flexural strength of the composite beams were
effectively increased thanks to the CFRP sheets. The 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 beams.
Adhesive debonding had a great influence on the strain distribution and deflection
of the composite specimens. It was an important factor for the failure of the
CFRP-bamboo scrimber composite specimens. According to the finite element
simulation, the strain distribution, contact pressure and deflection also greatly
changed with the adhesive debonding. After complete peeling, the deflection of
the specimen was 3.09 times that of the unpeeled because it was no longer an
integral beam.},
