Natural fibers compete with technical fibers, such as glass fibers or carbon fibers, as reinforcements for plastics. The advantages of technical fibers are their good mechanical properties, which vary only a little, but their recycling is difficult. 

The mechanical properties of composites are mainly influenced by the adhesion between matrix and fibers of the composite. As it is known from glass fibers, the adhesion properties could be changed by pretreatments of fibers. So special process, chemical and physical modification methods were developed. Moisture repel-lency, resistance to environmental effects, and, not at least, the mechanical properties are improved by these treatments. Various applications for natural fibers as reinforcement in plastics are encouraged. 

To provide this form material with the required rigidity, meshed glass fibers are added to the particle board as reinforcing material. By applying special resin to the surface of the material and cutting the glass fibers as required, rigid forms like plywood can be obtained. 

The ultimate goal of research in green composites is to replace the existing synthetic glass fibers with natural fibers as reinforcements and also to replace petroleum-based polymers with renewable-resource-based bipolymers as matrices in designing and engineering of biocomposite materials [33]. 

The high modulus of jute has, in turn, made jute materials a partial substitute for glass fiber as a reinforcement for polyester or epoxy resins in resin transfer technologies. It has not.

A wide range of biodegradable polyester-based composites is available in the new era of novel materials. Polyester-based composites are mainly manufactured by reinforcing with glass/carbon and natural fibers. The use of natural fibers as reinforcement has increased in the last two decades, because of their easy availability and degradable property. Polyester composites reinforced by glass or carbon fibers... 

Abstract A wide variety of natural fibers can be applied as reinforcement or fillers in composites. Bast fibers, such as fiax and hemp, have a long history of cultivation and use. They are characterized by low weight and excellent range of mechanical properties. The properties of bast fibers are influenced by conditions of cultivation, retting, and processing. Pretreatment and surface modification of bast fibers is conducted for optimization of the interfacial characteristics between fiber and matrix as well as improvement of their mechanical properties. Application of bast fibers as reinforcement to replace the glass fibers to composite manufacture brings positive environmental benefits.
