Abstract
The invention discloses the method for a kind of thermosetting fibre polymer composite post forming, fiber polymer composite after the first one-step forming of pultrusion, without be heating and curing or heat solidify not yet completely time, immediately with shaping bender secondary bending and molding, then carry out heat-shaping.The present invention is the muscle, rod, bar, the rope material that utilize fiber thermosetting polymer compound, in the basic hot briquetting of pultrusion, when solidifying not yet completely, namely carries out bending post forming, and then heat-shaping, naturally cools, forms product.Adopt method of the present invention have easy, continuously, do not need to make key technological transformation to equipment, the advantage that production cost is low, work efficiency is high.
Description
Technical field
The present invention relates to one and become the fiber polymer composite heat cure forming methods such as composite reinforcing, rod, bar, Suo Cai for heat reactive resin with each fiber (glass, basalt fibre or other synthetic fibers) pultrusion.
Background technology
Thermosetting fibre macromolecule composite reinforcing, rod, bar, Suo Cai, by fiber (glass fibre, aramid fiber, quartz fibre, basalt fibre and various organic polymer fiber), impregnated with thermoset macromolecular material (epoxy, ethene fat, unsaturated etc. resin), through pultrusion, be heating and curing and form.Due to thermoset macromolecule material be heated after namely there is heat cure reaction, cannot not become moltenly, insoluble, expendable network structure thing.So be that have can not the shaping shortcoming of secondary operations after general thermoset macromolecule material hot briquetting, the production application of product is restricted.
Method conventional is at present, fiber, after the preformed of macromolecule resin dipping, is put into required shaping mould, then put into baking oven and add thermoset forming.Shortcoming, need invest post forming equipment, cost is high, produces discontinuous.
Summary of the invention
The technical problem to be solved in the present invention overcomes technological deficiency recited above, provides the method for a kind of thermosetting fibre polymer composite post forming.
In order to solve technical problem recited above, the present invention takes following technical scheme:
The method of a kind of thermosetting fibre polymer composite post forming, the fiber polymer composite of pultrusion just after one-step forming, without be heating and curing or heat solidify not yet completely time, immediately with shaping bender secondary bending and molding, carry out heat-shaping again, concrete step is as follows:
Adopt two draw the traction of fixture segmentation alternating tensile or directly drawn by hauling machine, make the hot strength of fiber polymer composite constant; Pull out, without being heating and curing or heating not yet completely crued fiber polymer composite, enter shaping bender immediately, carry out secondary bending and molding; Then flexible heater or the box-shaped heater heat-shaping again of energy free bend is used.
As a kind of preferred version, the fiber polymer composite of one-step forming at the beginning of drying tunnel is heating and curing, depart from drying tunnel under hauling machine traction after, namely by the first traction clamp, under continuous traction, after fiber polymer composite enters bending forming machine, throw off, with flexible heater or the box-shaped heater heat-shaping again of energy free bend, after hauling machine continues to be drawn to certain length, by the second traction clamp, after fiber polymer composite is stressed, decontrol the first traction fixture; Enter next circulation, clamping, traction, bending, disengagement bender, with flexible heater or box-shaped heater heat-shaping again, second draw clamp, traction, relieving first draw fixture; Above-mentioned action goes round and begins again and forms continuous print bending, and the diameter of fiber polymer composite, length, geometry all can be changed arbitrarily in bending.
Wherein, fiber polymer composite is fiber polymer composite reinforcing, rod, bar or rope material.
The present invention is the muscle, rod, bar, the rope material that utilize fiber thermosetting polymer compound, at pultrusion just one-step forming, without be heating and curing or heat solidify not yet completely time, namely carry out bending post forming, and then heat-shaping, naturally cool, formation product.Adopt method of the present invention have easy, continuously, do not need to make key technological transformation to equipment, the advantage that production cost is low, work efficiency is high.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of an embodiment of the present invention.
Detailed description of the invention
Referring to Fig. 1, is the schematic flow sheet of an embodiment of the present invention.In figure, fiber polymer composite 1 is composite reinforcing, rod, bar, the composite reinforcing of one-step forming at the beginning of drying tunnel 2 is heating and curing, rod, bar, depart from drying tunnel under hauling machine 7 draws after, namely clamp with the first traction fixture 3, under continuous traction, protective sleeve 5 (such as flexible rubber pipe etc.) is used to be enclosed within muscle immediately, rod, bar (protection muscle, rod, bar does not damage) enter bender 4 bending and molding after, throw off, with can flexible heater 6 (or the box-shaped heater) heat-shaping again of free bend, hauling machine continues traction muscle, rod, after bar to certain length, by the second traction clamp, rod, muscle, after bar is stressed, decontrol the first traction fixture, enter next circulation, clamping, traction, bending, disengagement bender, with can the flexible heater of free bend or box-shaped heater heat-shaping again, second traction clamp, traction, relieving first draw fixture: above-mentioned action goes round and begins again the bending of formation one continuous print, make rod, muscle, shank diameter, length, geometry can bending change arbitrarily.
Although the present invention has been explained in detail and has quoted embodiment as proof, for those of ordinary skill in the art, the various schemes obviously can made according to above-mentioned explanation, amendment and change, within the scope that all should be included in claim.
