Abstract: Wheat straw is renewable, widely distributed, available locally, moldable, anisotropic, hydroscopic, recyclable, versatile, non-abrasive, porous, viscoelastic, easily available in many forms, biodegradable, combustible, compostible, and reactive. It also has a high aspect ratio, high strength-to-weight ratio, and has good insulation properties (sound, electrical, and thermal). The fiber structure is hollow and laminated, with molecular layers and an integrated matrix. Some might consider part of these properties as problems, such as biodegradable and combustible. but these features provide a means of predictable and programmable disposal not easily achieved with other resources. Many possible composite products can be made using wheat fibers including structural (using thermosetting resins) and nonstructural (using either a thermosetting or thermoplastic resin) materials, geotextiles and molded products (using fiber mats prepared by physical entanglement, nonwoven needling, or thermoplastic fiber-melt matrix technologies), sorbents and filters (for removing pollutants from contaminated air, water, and/or soil), packaging, and in products in combination of other resources. Success or failure in producing these products depends on many factors including codes and standards, economies of scale, availability of resources, energy and labor costs, resource handing, collecting and shipping, and overcoming historical biases. Wheat fibers can be combined with other resources such as plastics, glass, metals, and synthetics. The objective is to combine two or more materials in such a way that a synergism between the components results in a new material that is much better than the individual components. The properties of wheat fibers can also be modified through physical and chemical technologies to improve performance of the final composite.
