The conventional composites are replacing such well-established structural materials as steel, iron, and aluminum very fast. The conventional composites are not easily disposable. To overcome the problems of disposability and pollution, the focus is on the fabrication of natural composite materials. The natural composite materials are made from natural fibers and natural resins. Various natural fibers, such as jute, hemp, coir, cotton, and others are used in industry to fabricate natural composite materials.
Journal of Green Building 1 January ; 15 1 : — The use of recycled aggregate RA instead of natural aggregate NA in concrete is necessary for environmental protection and the effective utilization of resources. The addition of recycled aggregates in concrete increases shrinkage, porosity and decreases the mechanical properties compared to that of normal concrete. This study was aimed at investigating how the addition of various proportions of polypropylene and steel fiber affect the mechanical properties of recycled aggregate concrete RAC. In this case, a polypropylene fiber PF content of 0. While the material performance of RAC compared to NC is analyzed by reviewing existing published literature, it is not evident what the use of RCAs and hybrid fibers have on the mechanical properties of concrete.
A fiberglass is a form of fiber-reinforced plastic where glass fiber is the reinforced plastic. This is the reason perhaps why fiberglass is also known as glass reinforced plastic or glass fiber reinforced plastic. The glass fiber is usually flattened into a sheet, randomly arranged or woven into a fabric. According to the use of the fiberglass, the glass fibers can be made of different types of glass. Fiberglass is lightweight, strong and less brittle.
Textile fibers refer to filaments or threads which are woven, knitted, matted or bound to be used to make fabrics for different purposes. To put it in perspective, Fabric is made from yarns and yarn is made from fibers. As man advanced in textile technology he has discovered a variety of man-made as well as natural fibers which have been a boon to designers looking for different characteristics in the textiles they use to design their creations with. Hair fibers and wool fibers. Wool is the most popularly used animal fiber; it is obtained from the skin of different breeds of sheep.
Fiber or fibre from Latin: fibra  is a natural or man-made substance that is significantly longer than it is wide. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. Man-made or chemical fibers are fibers whose chemical composition, structure, and properties are significantly modified during the manufacturing process. Semi-synthetic fibers are made from raw materials with naturally long-chain polymer structure and are only modified and partially degraded by chemical processes, in contrast to completely synthetic fibers such as nylon polyamide or dacron polyester , which the chemist synthesizes from low-molecular weight compounds by polymerization chain-building reactions. The earliest semi-synthetic fiber is the cellulose regenerated fiber, rayon.
Synthetic fibers are generally semicrystalline polymers that are spun into filaments. The fibers are uniaxially oriented during the melt, dry, or wet spinning process, which give the fibers high tenacity and strength. The synthetic fibers are then converted to yarn by twisting several continuous fibers together to a uniform yarn with all filaments more or less alligned parallel to the yarn axis. Cellulosics are derived from naturally occuring cellulose through chemical reactions and processing. The most important types of cellulose based fibers are cellulose acetate Acetate , regenerated cellulose Viscose Rayon , Cuprammonium Rayon Bemberg , and saponified acetate Rayon.
