In the present chapter, rayon and other man-made cellulose fibers wUl be introduced in terms of properties and stracture. The compounding method to obtain the composites will be described briefly. PP-rayon composites will be considered in more detail as the practically most relevant class of this type of material at present arousing interest from the automotive industry. In another section rayon composites with poly(lactic acid) (PLA) and polyhydroxyalkanoates (PHA) will be studied as a promising bio-based and biodegradable alternative to conventional materials in durable applications, transport, and automotive industry. Finally, some concluding remarks will be given concerning future prospects of rayon reinforced thermoplastics and the problems to be tackled in future work. 

In order to develop composites with better mechanical properties and environmental performance, it becomes necessary to increase the hydrophobicity of the biofibers and to improve the interface between matrix and biofibers. Graft copolymerization of biofibers is one of the best methods to attain these improvements. As of now, only few studies have reported the use of biofiber graft copolymers as reinforcing material in the preparation of composites [33], Mechanical properties of thermoplastic composites reinforced with acrylate-gro/led henequen cellulose fibers were studied. It has been found that best results could be obtained with poly(methyl methacrylate) (PMMA)-grafted cellulose fibers because of better fiber-matrix adhesion. The modulus of poly(vinyl chloride) (PVC) composites is increased when grafted or ungrafted cellulose are used as reinforcement but the composites with...
