Abstract
The utility model relates to a kind of carbon fiber monofilament Mechanics Performance Testing fixture.Carbon fiber monofilament is more fragile, is difficult to, by adopting the direct clamping test of grip of testing machine, can produce certain injury to carbon fiber in addition by direct clamping test in Mechanics Performance Testing process, causes the inefficacy of experimental result.The utility model includes fixture and the sample scraps of paper; Fixture comprises upper stationary fixture and the lower stationary fixture of upper and lower corresponding, and the homonymy of upper stationary fixture and lower stationary fixture is respectively arranged with floating holder and lower floating holder; The sample scraps of paper be shaped as rectangular box, central authorities are the hollow out of rectangle, on hollow out rectangle, following midpoint is the point of fixity of carbon fiber monofilament, and sample scraps of paper upper side frame is sandwiched between stationary fixture and upper floating holder, and lower frame is sandwiched between lower stationary fixture and lower floating holder.The utility model has overcome the defect that existing testing apparatus cannot gripping carbon fiber monofilament, with the sample scraps of paper, glues clamping test after monofilament, not fragile sample.
Description
Technical field
the utility model belongs to carbon fiber monofilament mechanics performance testing technology field, is specifically related to a kind of carbon fiber monofilament Mechanics Performance Testing fixture.
Background technology
Carbon fiber monofilament mechanical property is an important indicator of carbon fiber, at present domestic not relevant concrete national standard, the external relevant criterion of industry build-in test Main Basis operates, fragility due to carbon fiber monofilament, cause just in test process, being difficult to by adopting the direct clamping test of grip of testing machine, in addition by direct clamping test, can produce certain injury to carbon fiber, cause the inefficacy of experimental result.Domestic current use be domestic strength of filament instrument, when test carbon fiber strength of filament, directly test is difficult to operation, cannot obtain valid data, with the sample scraps of paper, also cannot operate.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon fiber monofilament Mechanics Performance Testing fixture, improves the operability of test, guarantees the accuracy of test.
The technical scheme that the utility model adopts is:
A carbon fiber monofilament Mechanics Performance Testing fixture, is characterized in that:
Include fixture and the sample scraps of paper;
Described fixture comprises upper stationary fixture and the lower stationary fixture of upper and lower corresponding, and the homonymy of upper stationary fixture and lower stationary fixture is respectively arranged with floating holder and lower floating holder, fixture height 10mm, width 25mm;
The described sample scraps of paper be shaped as rectangular box, width 25mm, central authorities are the hollow out of rectangle, on hollow out rectangle, following midpoint is the point of fixity of carbon fiber monofilament, sample scraps of paper upper side frame is sandwiched between stationary fixture and upper floating holder, and lower frame is sandwiched between lower stationary fixture and lower floating holder.
Upper floating holder and lower floating holder one side are provided with air pressure pump, and upper floating holder and lower floating holder are pushed into upper stationary fixture and lower stationary fixture by air pressure pump.
The utlity model has following advantage:
The utility model has overcome the defect that existing testing apparatus cannot gripping carbon fiber monofilament, in conjunction with strength of filament instrument, with the sample scraps of paper, glues clamping test after monofilament, can effectively draw the mechanical property of carbon fiber monofilament, simple to operate, not fragile sample.

Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
A kind of carbon fiber monofilament Mechanics Performance Testing fixture that the utility model relates to, coordinates strength of filament instrument to clamp the mechanical property of carbon fiber monofilament, includes fixture and the sample scraps of paper.Fixture comprises upper stationary fixture 1 and the lower stationary fixture 3 of upper and lower corresponding, and width is 15mm, is highly 15mm, and thickness is 25mm, and the distance between upper stationary fixture 1 and lower stationary fixture 3 is 30mm.The homonymy of upper stationary fixture 1 and lower stationary fixture 3 is respectively arranged with floating holder 2 and lower floating holder 4, and width is 15mm, is highly 15mm, and thickness is 25mm.Upper floating holder 2 and lower floating holder 4 one sides are provided with air pressure pump, and upper floating holder 2 and lower floating holder 4 are pushed into upper stationary fixture 1 and lower stationary fixture 3 by air pressure pump.The sample scraps of paper be shaped as rectangular box, central authorities are the hollow out of rectangle, outer width of frame is 25mm, length is 40mm, interior width of frame is 15mm, length is 25mm.On hollow out rectangle, following midpoint is the point of fixity of carbon fiber monofilament, and sample scraps of paper upper side frame is sandwiched between stationary fixture 1 and upper floating holder 2, and lower frame is sandwiched between lower stationary fixture 3 and lower floating holder 4.
During test, the sample scraps of paper that glue monofilament are clamped between upper lower clamp, by air pressure pump, first upper floating holder 2 and upper stationary fixture 1 are compressed, with air pressure pump, lower floating holder 4 and lower stationary fixture 3 are compressed again, the sample scraps of paper are cut off scraps of paper the right and left after clamping, and carry out tension test just can test out the mechanical property of carbon fiber monofilament with monofilament machine.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model instructions, is claim of the present utility model and contains.
