One of the main issues with using natural reinforcing fibers is poor adhesion to the matrix. Through the use of new chemistry, this problem will be alleviated for cellulose and lignin. Both physical and chemical bonding to a variety of matrices ranging from low polarity, chemically inert (e.g., polyolefins) materials to those bearing highly polar, reactive substituents (e.g., epoxy resins) are feasible. The potential to tailor some of the physical properties of these natural materials is also a distinct possibility. Fibers can be derivatized in a manner that allows for a variety of cure types including radiation, heat, or chemical. Fibers can also be woven and cured into monolithic structures.
