The paper presents comparative results of the local combustion of 24 full scale beams, statically loaded, made of wood-CFRP composite and glue laminated timber. An effort of the samples was 90%, in the class of glue laminated timber GL24h. The combustion time until beams’ failure, deflection increment and element temperature were measured. Summarising the gathered results, a trend allowing to conclude that CFRP tapes used inside the cross-section can increase the fire resistance of the beams is noticeable, but they must be protected by the wood during fire exposure.
