Abstract
A zero-degree fibre winding method for making the glass fibre reinforced plastic pipe includes such steps as winding the non-woven fabric and glass fibres, which have been immersed in resin, respectively on the surface of formwork from its lower part in tangent direction, winding the unidirectional or latticed glass fibre close is same mode, spraying resin, winding annular fibre layer, adding sand, and repeating the steps 2 and 3.
Description
Technical field
The present invention relates to a kind of GRP pipe zero degree fiber winding method, particularly relate to a kind of GRP pipe zero degree fiber winding method that adopts glass fibre unidirectional cloth or grid cloth.
Background technology
GRP pipe is a kind of composite material tube, and it is to carry out multi-lay winding and make at die surface behind glass fibre and the resin prepreg.Winding system at present commonly used is to utilize glass fibre that wind on the walking dolly that is arranged on the workbench and can moves along the workbench length direction will be soaked with resin to introduce from the tangential direction towards the GRP pipe mould bottom of workbench direction rotation, and its surface at mould is successively twined, until the thickness that reaches desired structure sheaf of pipeline and superficial layer.The program of twining is normally carried out nonwoven and glass fibre earlier along the surface of GRP pipe mould hoop twines, and when waiting to reach certain thickness, the intersection of carrying out glass fibre is again twined, to increase the axial force of pipeline.Like this repeated multiple times promptly can be made into the GRP pipe of certain specification.Intersecting in the winding process, glass fibre and GRP pipe mould axially between angle more little, then axial strength is high more, minimum usually can only 55 °, if less than this angle, glass fibre just easily influences the quality of pipeline when oppositely twining in the slippage of mouth of pipe place.If greater than 60 °, then pipeline axial intensity reduces, and needing additional multilayer to intersect to twine could increase axial strength.In addition, the angle of twining of intersecting needs to control with computer, not only need high control precision, and supplementary equipment therefore is many, thereby the difficulty of operation is bigger.Because the axial strength of GRP pipe is mainly formed by the glass fibre of arranging vertically, above-mentioned hoop twines does not have the fiber of arranging vertically, can only play the effect that increases hoop intensity, and the fiber that intersection is twined is also with axially in a certain angle, fiber can not bear the straight line pulling force, can not directly play increases the axial strength effect, so as if the axial strength of wanting to reach required, just need back and forth to twine multilayer, thereby not only the intensity and the production efficiency of pipeline is low, and the equipment complexity, thereby production cost is raise.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of pipeline intensity and production efficiency height, production cost is low and the simple GRP pipe zero degree of equipment fiber winding method.
In order to achieve the above object, GRP pipe zero degree fiber winding method provided by the invention carries out according to the following order step:
(1) will be soaked with the nonwoven of resin and glass fibre from the tangential direction of GRP pipe mould bottom respectively hoop be wrapped in the surface of mould and make the GRP pipe inner liner;
(2) being the glass fibre unidirectional cloth of 200～300mm or grid cloth with width is wrapped in the surface of mould from the tangential direction hoop of GRP pipe mould bottom, above the GRP pipe mould resin spray is made unidirectional cloth or grid cloth hoop structure sheaf on the surface of unidirectional cloth or grid cloth simultaneously;
(3) twine the hoop fibrage according to the specification and the designing requirement of pipeline;
(4) under the situation of making the fiberglass sand-adding pipe, use the common sand method that adds to make and add layer of sand;
(5) repeat above-mentioned steps 2 and promptly can be made into GRP pipe to step 3 with certain intensity.
Described glass fibre unidirectional cloth is that glass fibre parallel with many and that have a certain-length is made and made along perpendicular direction.
Described fiberglass gridding cloth is to be formed by the fiberglass braided of square crossing.
GRP pipe zero degree fiber winding method provided by the invention is to utilize the hoop of glass fibre unidirectional cloth or grid cloth to twine the glass fibre intersection winding that replaces prior art, so not only can make the intensity of GRP pipe improve 2.5 times, but also can improve 30% production efficiency.Grid cloth can increase hoop intensity when strengthening axial force.In addition, production cost can descend 30%, and production equipment is simple.
Description of drawings
Below in conjunction with the drawings and specific embodiments GRP pipe zero degree fiber winding method of the present invention is elaborated.
Fig. 1 is the wind schematic diagram when adopting glass fibre unidirectional cloth fw frp pipeline.
Fig. 2 is the wind schematic diagram when adopting fiberglass gridding cloth fw frp pipeline.
The specific embodiment
As mentioned above, owing to the glass fibre unidirectional cloth is that glass fibre parallel with many and that have a certain-length is made along perpendicular direction and made, and fiberglass gridding cloth is to be made by the fiberglass braided of square crossing, when utilizing unidirectional cloth or grid cloth to carry out the hoop winding, glass fibre length direction on the pipeline is axially identical with GRP pipe, thereby can increase substantially the axial strength of GRP pipe.As Fig. 1, shown in Figure 2, when carrying out the GRP pipe winding, carry out the hoop winding of nonwoven and glass fibre earlier according to the method for prior art, when twining to required inner liner thickness, the hoop that available same set of device carries out glass fibre unidirectional cloth 2 or grid cloth 4 twines, promptly utilize the wind on the walking dolly 5 be arranged on the workbench 1 and can move along workbench 1 length direction that glass fibre unidirectional cloth 2 or grid cloth 4 are introduced from the tangential direction towards GRP pipe mould 3 bottoms of workbench 1 direction rotation, and its surface at mould 3 is twined, between twining, two circles require to have the overlap joint of 2.5cm, simultaneously above GRP pipe mould 3 with the surface of resin spray at unidirectional cloth 2 or grid cloth 4, when waiting to reach desired thickness, carry out such as adding follow-up windings such as sand according to the requirement of pipeline again.Adopt with prior art and to intersect the GRP pipe that winding method makes and compare, the GRP pipe that utilizes method of the present invention to make will be saved about 165～300 yuan expense by the every mitrons of specification difference road length, thereby remarkable in economical benefits.In addition, in the present invention, owing to almost do not have angle between glass fibre and GRP pipe mould axial, so be easy to operate and control.
