Abstract: 
This work presents results of an experimental program on the mechanical properties of a new class of textile composite developed using vegetable sisal fiber as reinforcement. A multi-layer composite was manufactured by a hand lay out of the fibers in 5 layers and posterior compression. The single filament fibers were stitched together, side by side, forming a unidirectional fabric. The influence of reinforcement ratio, ranging from 2 to 10 %, was investigated by means of direct tension and four point bending tests. Results have indicated that 10% is the fiber volume fraction that maximizes the mechanical properties of the composites. Maximum strength values under four point bending, direct tension and bending toughness of, respectively, 18.53 MPa, 8.03 MPa and 20.30 kJ/m2 were obtained, indicating the potentiality of the new material for structural applications in the sustainable construction industry.
