Too few opinions date December 2010 NOTOC A fiber reinforced composite FRC consists of three components i the fibers as the discontinuous or dispersed phase, ii the matrix as the continuous phase, and iii the fine interphase region, also known as the interface ref name cantwell cite journal author WJ Cantwell, J Morton title The impact resistance of composite materials a review journal Composites year 1991 volume 22 issue 5 pages 347&ndash 62 url doi 10.1016 0010 4361 91 90549 V ref ref name serope Serope Kalpakjian, Steven R Schmid. Manufacturing Engineering and Technology . International edition. 4th Ed. Prentice Hall, Inc. 2001. ISBN 0 13 017440 8. ref . This is a type of advanced composite group, which makes use of rice husk, rice hull, and plastic as ingredients. This technology involves a method of refining, blending, and compounding natural fibers from cellulosic waste streams to form a high strength fiber composite material in a polymer matrix. The designated waste or base raw materials used in this instance are those of waste thermoplastics and various categories of cellulosic waste including rice husk and saw dust. Image Gal main.jpg thumb Fiber reinforced composite 300px right FRC is high performance fiber composite achieved and made possible by cross linking cellulosic fiber molecules with resins in the FRC material matrix through a proprietary molecular re engineering process, yielding a product of exceptional structural properties. Through this feat of molecular re engineering selected physical and structural properties of wood are successfully cloned and vested in the FRC product, in addition to other critical attributes to yield performance properties superior to contemporary wood. This material, unlike other composites, can be recycled up to 20 times, allowing scrap FRC to be reused again and again. The failure mechanisms in FRC materials include delamination , intralaminar matrix cracking, longitudinal matrix splitting, fiber matrix debonding, fibe ... more details

Ivory carving is a decorative art or craft practised since prehistoric times. Its Conservation restoration conservation is concerned particularly with the environmental causes of deterioration. Ivory Ivory is the term for the tusks and teeth of mammals including the elephant , hippopotamus , warthog , wild boar , walrus , narwhal , and mammoth .
