Abstract text:
The flexural behavior of hybrid systems made of wood and carbon fibre reinforced polymer (CFRP) composite strips subjected to bending is analysed in this paper. The analysis is completed with an optimization study, based on the percentage of CFRP reinforcement and the strength classes of wood, relating to the hybrid beams. The results obtained from the analytical study are compared to those determined from numerical modelling, revealing the efficiency of the discussed reinforcing solutions based on CFRP strips. Finally, the authors highlight the importance of using these hybrid systems to achieve lightweight structures with convenient properties that meet the design requirements imposed by using large spans and resisting additional loads.
Key Words:
CFRP strips; wood beams, hybrid system; stiffness; numerical modelling.
