The results of an experimentation on beams in solid wood reinforced with FRP in natural fibers of basalt, flax and hemp are presented. In the first phase, the properties of the materials to be used were studied. Tension tests and pool-out tests were performed on specimens made up of different types of fibers. In the second phase three series of different size wooden beams were prepared applying natural fiber reinforcements and were then subjected to bending tests on four points. The results of the natural fibers reinforced beams were compared with those obtained on the beams with no reinforcement or reinforced with traditional glass or carbon fibers. The structural behaviour was satisfactory: the reinforced beams showed strength and stiffness higher than beams without any reinforcement and a good behaviour when compared to beams reinforced with carbon or glass fibers.

Abstract

The results of an experimentation on beams in solid wood reinforced with FRP in natural fibers of basalt, flax and hemp are presented. In the first phase, the properties of the materials to be used were studied. Tension tests and pool-out tests were performed on specimens made up of different types of fibers. In the second phase three series of different size wooden beams were prepared applying natural fiber reinforcements and were then subjected to bending tests on four points. The results of the natural fibers reinforced beams were compared with those obtained on the beams with no reinforcement or reinforced with traditional glass or carbon fibers. The structural behaviour was satisfactory: the reinforced beams showed strength and stiffness higher than beams without any reinforcement and a good behaviour when compared to beams reinforced with carbon or glass fibers.
