In the present study, fiber‐reinforced plastics (FRP) were prepared with sisal and the sugarcane waste material. The composites of these fibers with polyurethanes were obtained by processing these materials in a Haake plastograph, and their homogeneity was characterized by nuclear magnetic resonance (NMR) measurements. The results are discussed in terms of composites interaction, homogeneity, and compatibility. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 1465–1468, 2002
