Reinforced plastics filament winding

Balanced design n. In reinforced plastics, a winding pattern so designed that the stresses in all filaments are equal. Pittance JC (ed) (1990) Engineering plastics and composites. SAM International, Materials Park, OH. 

For typical filament winding applications, the fiber reinforcement provides the stiffness and strength required to maintain structural integrity. Thus, material characterization for filament wound structures focuses on characterizing the fiber dominated stiffness and strength properties of the composite. The stiffness of fiber reinforced plastics (FRPs), in the fiber direction, is dominated by the fiber stiffness characteristics. The strength will be influenced by a number of factors, however, and not all of them are related to the fiber, including ... 

Corrosion Resistant Fiber-Reinforced Plastic (FRP), Fiber glass reinforcement bonded with furfuryl alcohol thermosetting resins provides plastics with unique properties. Excellent resistance to corrosion and heat distortion coupled with low flame spread and low smoke emission are characteristics that make them valuable as laminating resins with fiber glass (75,76). Another valuable property of furan FRP is its strength at elevated temperature. Hand-layup, spray-up, and filament-winding techniques are employed to produce an array of corrosion-resistant equipment, pipes, tanks, vats, ducts, scrubbers, stacks, and reaction vessels for industrial applications throughout the world. 

Continuous-fiber reinforcement gives plastic products which are not simply quantitatively, but often qualitatively, superior to most present commercial practice. Most plastic processing is limited to conventional melt flow of short-fiber reinforcements, which sacrifices much of the potential benefits of reinforcement. There are a few processes for incorporating continuous fiber reinforcement—filament-winding, pultru-sion, swirl conformation of fibers in polymer... 

Filament winding (FW) is a fabrication technique for forming reinforced plastic parts of high strength/modulus and lightweight. It is made possible by exploiting the remarkable strength properties of their continuous fibers or filaments encased in a matrix of a resinous material. For this process, the reinforcement consists of filamentous non-metallic or metallic materials processed either in fibrous or tape forms.488 489...
