Abstract

The utility model relates to a fiber-reinforced draw-extrude plastic pipe, which is paved with six layers of reinforcement fibre. The first floor is longitudinally paved in a single direction; the second layer is also longitudinally paved in a single direction; the third layer is winded in a clockwise direction or an anticlockwise direction; the fourth layer is longitudinally paved in a single direction; the fifth layer is winded in a clockwise direction or an anticlockwise direction; the sixth layer is longitudinally paved. The utility model has the advantages that the torsion performance and the circumferential strength are enhanced, and the pipe diameter is small to reach 5.5 millimeters. The utility model can be used in the fields of chemical industry, light industry, electricity, etc., and is especially suitable for manufacturing umbrellas, tents, etc.

Description

Fiber-reinforced draw-extrude plastic pipe

It is reinforcing material that the utility model relates to the fiber, is base material with synthetic resin, has the plastic tube of multilayer reinforcing fiber, relates in particular to small diameter fibers and strengthens drawing-extruding plastic tube.

With the fibre reinforced plastic tube of traditional pultrusion manufactured, have only vertical unidirectional reinforcing fiber layer, hoop intensity and distortion performance are not high, therefore limit its application area.The fibre reinforced plastic tube with fiber winding layer that adopts fiber winding method to make is also arranged in addition, though to a certain degree improved plastic tube hoop intensity and distortion performance, but because it falls, does not have long grain fiber along between the winding layer, influenced the mechanical strength of plastic tube, and do not seen that so far diameter is less than 12 millimeters fibre reinforced plastic tube.

The purpose of this utility model is to provide a kind of falls, the small diameter fibers wound plastic tube of long grain fiber layer is arranged between the clockwise direction winding layer.

The purpose of this utility model can reach by following technical solution: be reinforcing material with the fiber, with synthetic resin is base material, first series of strata are vertically laid layer of fibers, the second layer also is vertical unidirectional laying layer of fibers, the 3rd series of strata are twined layer of fibers along (contrary) clockwise hoop, the vertical unidirectional laying layer of fibers of the 4th series of strata, contrary (suitable) clockwise hoop of layer 5 system twines layer of fibers, and layer 6 is vertical unidirectional laying layer of fibers.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a manufacturing process schematic representation of making the utility model plastic tube.

Fig. 2 is the utility model fiber reinforcing drawing-extruding plastic tube part sectional arrangement drawing.

Fig. 3 is the utility model fiber reinforcing drawing-extruding plastic tube part drawing in side sectional elevation.

As Fig. 1,2, shown in 3, fiber 2 through resin impregnation is vertically spared the surface of cloth at core 1, advance in the direction of arrows under the effect of tractive force outside, be solidified into unidirectional fibre reinforced plastic pipe 4 through heating pultrusion mould 3, become first layer 17, then at the fiber 5 of the vertically even cloth of the outer surface of plastic tube 4 through resin impregnation, become the second layer 12, outer surface at fiber 5 twines fiber 6 by counterclockwise (or clockwise) direction spiral, become the 3rd layer 13, twine the fiber 7 of the vertically even again cloth of outer surface of fiber 6 at spiral through resin impregnation, become the 4th layer 14, outer surface at fiber 7 twines fiber 8 by clockwise (or counterclockwise) direction spiral again, become layer 5 15, twine the fiber 9 of the vertically even again cloth of outer surface of fiber 8 at spiral, become layer 6 16, after heating pultrusion mould 10 is solidified into the utility model 11 with it through resin impregnation.

The existing vertical unidirectional reinforcing fiber layer of the utility model fiber reinforcing drawing-extruding plastic tube has hoop spiral winding layer again, thereby distortion performance and hoop intensity have been improved, caliber can reach 5.5 millimeters for a short time, be widely used in chemical industry, light industry, field such as electric, be specially adapted to make umbrella, tents etc.

Claims

1, a kind of fiber reinforcing drawing-extruding plastic tube, with the fiber is reinforcing material, with synthetic resin is base material, fibre reinforced plastic tube with multilayer reinforcing fiber, it is characterized in that: lay 6 layers of reinforcing fiber, first layer 17 is vertical unidirectional laying layer of fibers, the second layer 12 also is vertical unidirectional laying layer of fibers, the 3rd layer 13 is to twine layer of fibers along (contrary) clockwise hoop spiral, the 4th layer 14 is vertical unidirectional laying layer of fibers, layer 5 15 is that contrary (suitable) clockwise hoop spiral twines layer of fibers, and layer 6 16 is vertical unidirectional laying layer of fibers.
