Description
Technical field
The utility model is related to tow shape Tensile strength measuring technology, and in particular to minor diameter after test fused salt corrosion
Tow shape Tensile strength fixture.
Background technology
In order to reclaim the carbon fiber in carbon fiber reinforced epoxy resin-based composite, the composite is immersed into high temperature melting
Melt in salt bath, high polymer material is gasified, leave carbon fibre material.But the carbon fiber surface after high-temperature molten salt is handled is rotten
Erosion, material property has occurred that change, it is necessary to its mechanical property of test analysis.And tensile strength is to characterize the mechanics of materials
One important indicator of energy.At present, electronic universal tester is when testing the tensile strength of various materials, and clamped material leads to
It is often circular section bar and square-section sheet material.And small diameter wire strand material cross-sectional area is small, such as standard carbon fiber single straight
Only 7 μm of footpath, single clamping is difficult, and multi-filament beam can only be clamped simultaneously.By taking carbon fiber as an example, commercially available specification is generally 24K（Close
24000）, tow quantity is larger, when directly being clamped using routine test machine, it is impossible to ensure every all synchronous uniform stressed
To two side stretchings, easily cause reel off raw silk from cocoons, skidding, cause experimental result inaccurate.
The problem of to solve silk strand material extension test, the CN105043840A inventions of Physic ＆ Chem. Engrg. Inst., Ministry of Nuclear Ind
Patent discloses a kind of large-tow carbon fiber and stretches sample preparation method of having a try, and passes through the method for two ends impregnation in triangular mould
Tensile sample is prepared, but because carbon fiber class small diameter wire strand material diameter is very small, specific surface area is big, in gel solidification mistake
Adsorption air is more in journey, and gumminess is big, and tow adsorption has air, it is difficult to overflow, and part tow surface is drawn without glue
Easily caused when stretching and reel off raw silk from cocoons, skid.The CN205209881U patents of the China Measures Institute disclose a kind of measurement glass fibers Wella
The fixture of intensity is stretched, the method for fixing glass fibre by upper and lower wired device carries out extension test, but wired device is not wired smart
Really, stress deviation is also easy to produce, and operation is relatively complicated, is not suitable for using in midget plant or laboratory.
The content of the invention
The purpose of this utility model is to provide small diameter wire strand material tensile strength after a kind of test fused salt corrosion and pressed from both sides
Tool.
The utility model is small diameter wire strand material tensile strength fixture after a kind of test fused salt corrosion, described a set of
Fixture is made up of completely identical in structure two groups of chucks, wherein every group of chuck includes left clamping plate 1, right clamping plate 5 and a pitman
2；Left clamping plate 1 and right clamping plate 5 are that, along a line band cube structure jaggy, the two clamping plates pairing, two breach are combined into
One semicircular groove 4 is arranged at one U-type groove structure, U-type groove bottom, and the involutory surface of its axis and left clamping plate 1 and right clamping plate 5 hangs down
Directly, it is with being in 30 ° of angles to zygonema；Pitman 2 is placed with groove 4, funnelform hole clipping is provided with U-type groove bottom center
3, its lower end is wavy holes for clamping 7, and steps up diameter of the diameter of hole 7 more than the other end close to the end of hole clipping 3, and end is in
Equal diameter straight hole.
The beneficial effects of the utility model：1. and the combination of fixture solves the problem of clamping is inconvenient, overcomes omnipotent examination
The machine of testing can not clamp the shortcoming of a strand material；2. the material surface after fused salt corrosion there may be damage and defect, and knot
The complex external force effect such as there is bending at position, reverse, the preferential stress at knotting position is concentrated and excellent when being easily caused stretching
First it is broken.The present invention not only with gluing method, and use the up big and down small structure of wavy holes for clamping 7, slow down this because
It is dangerous caused by plain.3. avoid running, skidding during the design that knots tension test.4. the fixture is with low cost,
It is small volume, safe and reliable, practical flexible, it is workable, it is ensured that the degree of accuracy of test.
