%X Timber is the oldest construction materials in the world, have been widely used in structures in addition to having a high longevity, if treated properly (maintenance). If this does not occur, the wood deteriorates due to the action of insects, fungi and other aggressive agents. There are several materials and techniques used to reinforce the damaged parts. This paper presents an experimental study ofEucalyptus grandis and Pinus elliiottiitimber beams reinforced with sisal fibres laminated composite materials. The composite material and the wood were prepared for testing. In order to simulate the defect, some parts were cracked. The study was to determine the maximum load (rupture) applied on the timberin the conditions: without defect, with defect and without composite and with defect and with composite, aiming to verify the efficiency of the laminate as reinforcement in the wooden beams. The experimental results indicate the possible use of the laminated composite as reinforcement, presenting considerable increase in the maximum strength supported by the timber when compared to unreinforced cracked condition, being more efficient for the Pinus elliiottii species.
