Thermoplastic Filament Winding

The typical resin systems include thermoset polyesters, vinyl esters, epoxies, polymi-dies, bismaleimide, and phenolics. Thermoplastics are also finding their way into filament winding. Wet thermoset filament winding requires a resin with viscosity in the range of 1000-3000 cpoise. Resin components are chosen on the basis of pot life, winding temperature, viscosity, gel time, and cure time. [Pg.801]

Process models allow composite case manufacturers to determine the affects of process variable settings on final cylinder quality. Because the cost of a composite cylinder can be as great as 500,000, the ability to simulate filament winding can significantly reduce cost and improve quality. Several computer models of the filament-winding process for both thermoset and thermoplastic matrix materials have been developed. These models are based on engineering principles such as conservation of mass and energy. As such, numerous resin systems and fiber materials can be modeled. [Pg.398]

Consolidation and development of interlaminar bond strength for thermoplastic matrix composites have been modeled by two mechanisms intimate contact and autohesion. Intimate contact describes the process by which two irregular ply surfaces become smooth (Fig. 13.10). In areas in which the ply surfaces are in contact, autohesion occurs, and the long thermoplastic polymer chains diffuse across the ply boundaries. Filament winding with thermoplastic matrix materials is considered an on-line consolidation process in that local... [Pg.404]

Most high performance applications in aircraft use epoxy-based resin systems. Silicones, phenolics and polyimides are limited to special high temperature or electrical applications. Although thermosetting resins such as epoxy are commonly used in filament winding, there has been recent research into using thermoplastic matrix materials [9]. [Pg.60]

Fiber placement is basically a hybrid of filament winding and tape laying and is a continuous process for fabricating composite shapes, by laying thermoset or thermoplastic preimpregnated tows (in tow or slit tape form) onto a mandrel or tool having concave or convex surfaces. There is no limit to the fiber angle and tows can be added or removed as and when necessary. [Pg.921]

For thermosets, the hollow part processes are filament winding and pultrusion. These processes are limited in shape and structure. There are three hollow part processes for thermoplastics (1) rotational molding, (2) twin sheet thermoforming, and (3) blow molding. [Pg.261]

Laser welding has also been used for filament winding of fiber-reinforced composite materials with a thermoplastic prepreg. A defocused laser beam is directed on areas where the prepreg meets the winding as it is being built up. With suitable control over the winding speed, applied pressure, and the temperature of the laser, excellent reinforced structures of relatively complex shape can be achieved. [Pg.316]
