Abstract
The invention discloses a glass fiber reinforced plastic pressure tube and a preparation method thereof; the preparation method comprises the following steps: the fiber felt reinforced material structure of an inner surface layer is continuously paved to cover the outside of a mandrel coating with a parting agent, and then is immerged into the resin to form the inner surface layer structure; a hanging resin filament thread structure layer which is arranged in a cycle and extends longitudinally along the tube wall and a hanging resin filament thread structure layer which is continuously wound or woven along the tube wall are continuously paved outside the inner surface layer at internals, thus forming a alternate composite layer; the fiber felt reinforced material structure is continuouslypaved outside of the alternate composite layer, immerged into the resin, and then cured for shaping by a heater sheathed outside the glass tube wall. The tube wall is composed of at least six layers of fiber reinforced material structures spaced alternately, which leads a reinforced structure to be arranged between two layers of another reinforced structures, and effectively ensures that each reinforced structure is not affected and damaged and a stable structure resisting various stresses is available, therefore, the invention has higher capability to resist the internal pressure.
Description
Technical field: glass fiber reinforced plastic manometer tube and preparation method thereof be by glass fibre reinforced plastics be material through continuously outside core forming and hardening constitute the tubing that bears pressure and the technological method of working process, particularly constitute and bear pressure tubing and continuous manufacture method by the laminated glass steel structure.
Background technique: existing glass fiber reinforced plastic manometer tube and preparation method thereof, all be outside core, to smear releasing agent continuously, outside scribbling the core of releasing agent, constitute the glass fibre reinforced plastics tube wall continuously by the fibre reinforced materials of invading resin and also extract core after the curing, invade resin by fibre reinforced materials and constitute the glass fibre reinforced plastics tube wall, the structure of fibre reinforced materials has along tube wall twines or braiding, structure along the fiber of the longitudinal extension of pipe along circumferential array is also arranged, and also have composite structrue layer Glass Steel Tube these structure random combination.But this random combination composite structrue layer Glass Steel Tube can not satisfy the complicated applied force of multidirectional structure stress, moment of flexure and moment of torsion.The internal layer that technical process has solidify earlier qualitative after again cladding solidify outerly, cause easily delamination, reduced the intensity of tubing; Invade fiberglass behind the two-layer or two-layer above fibrage of the cladding that has together, so that between the fiber that is in contact with one another, particularly can not invade resin between the fibrage, cause the mechanical strength between the fiber of contact to reduce.
Summary of the invention:
The present invention solves existing glass fiber reinforced plastic manometer tube can not bear complicated applied force, technical problem that intensity is lower, and a kind of glass fiber reinforced plastic manometer tube and preparation method that can overcome the distortion that complicated applied force produces is provided.
In order to address the above problem, glass fiber reinforced plastic manometer tube of the present invention, be to invade resin by fibre reinforced materials to constitute the glass fibre reinforced plastics tube wall, it is characterized in that: glass tube walls is made of at least six layers of fibre reinforced materials structure, the inner and outer surface layer is a fibrofelt reinforcing material structure, between the inner and outer surface layer for arrange a week and along the fibre reinforced materials construction layer of tube wall longitudinal extension with twine continuously along tube wall or the fibre reinforced materials construction layer alternate intervals composite bed of braiding.Such alternate intervals, make a kind of anti-expansion winding or braiding structure between the structure of two-layer bend resistance, the structure both sides that effectively guarantee anti-expansion are not bent stressed impact and destruction, ensure stable anti-expansion structure, so can have the ability of higher anti-internal pressure.Equally, the structure of a kind of bend resistance and distortion two-layer anti-expansion twine or the structure of braiding between, the structure both sides that effectively guarantee bend resistance do not expanded stressed impact and destruction ensure stable bend resistance structure.So also stablized the stressed ability of anti-Various Complex with regard to having formed to have, guaranteed under the stress of Various Complex, also can keep having very high strength capabilities.Inside and outside fibrofelt reinforcing material structure can effectively guarantee extraneous local assault or bump or extruding, effectively prevents bigger crackle, extends and destroys inner fibrous structure, the intensity of anti-other abilities of influence.Glass fiber reinforced plastic manometer tube preparation method of the present invention, continuous smearing release agent outside core, outside scribbling the core of releasing agent, consist of continuously the fiberglass tube wall by the fibre reinforced materials of invading resin and also extract core after the curing, it is characterized in that: outside core, clad continuously the fibrofelt reinforcing material structure of laying interior surface layers, and the intrusion resin, form glass tube walls interior surface layers structure; Outside the interior surface layers that forms, be continuous laying and alternately arranged one round and along the extension resin fibre silk thread structure sheaf of tube wall longitudinal extension with along the extension resin fibre silk thread structure sheaf of tube wall continuous winding or braiding, form the alternate intervals composite bed; The fibrofelt reinforcing material structure of interior surface layers is laid in the outer continuously cladding of alternate intervals composite bed, and invades resin, forms glass tube walls outer surface layer structure, carries out sizing and solidifying with being enclosed within the outer heater of glass tube walls outer surface layer structure.Clad continuously the fibrofelt reinforcing material structure of laying interior surface layers, and after invading resin, carrying out continuous shaping preformed with ferrule mold.In continuous laying alternate intervals composite bed process, carry out continuous shaping pre-shaping with ferrule mold.
