Description
Technical field
This utility model relates to carbon fiber performance detection technique field, more particularly, it relates to a kind of carbon fiber multifilament for tension test.
Background technology
Carbon fiber (carbonfiber, it is called for short CF) it is that a kind of phosphorus content has a series of excellent properties such as high specific strength, high ratio modulus, high temperature resistant, corrosion-resistant, endurance, radioprotective, conduction, heat transfer, damping, noise reduction and relative density be little more than 95%, belong to typical high-performance fiber.It not only has the intrinsic intrinsic property of material with carbon element, has both again the soft machinability of textile fabric, is a new generation's fortifying fibre.As the one of high-performance fiber, carbon fiber carbon material obtains extensive use in military and civilian industry every field, from civilian industries such as space flight, aviation, automobile, electronics, machinery, chemical industry, light textiles to sports equipment and leisure goods etc..Therefore, carbon fiber is considered as the Typical Representative of infant industry material in high-tech area, has development prospect widely.
The main contents of carbon fiber stretching mechanical property testing include: hot strength, tensile modulus of elasticity, elongation at break, body density, line density etc., its method of testing has had standard GB/T/T3362-2005 " carbon fiber tensile property of multi-filament method of testing ", needs carbon fiber multifilament is carried out dipping process in this standard before test.The foreign standards such as the standard test method of Unite States Standard ASTMD4018 carbon fiber filament and graphite fibre tow performance and Nippon Standard JISK7073-1988 also all adopt the method test carbon fiber multifilament hot strength of pre-impregnation.GB/T3362-2005 standard manual method impregnation, the i.e. multifilament of clip 500mm length, entering impregnation in glue with hand-held firmly two ends, in standard, regulation test sample is 10 samples, so manual method impregnation is relatively complicated and it is difficult to ensure that the accuracy of test result.Universal testing machine is when doing carbon fiber multifilament and stretching test by force, it is necessary to clamping sample, easily produces carbon fiber and skid in process of the test and accommodate the sample problem at fracture of root in sample holder process.
Chinese utility model patent: CN203629959U, it is provided that testing machine stretched by force by a kind of carbon fiber and the fixture of test stretched by force by detection carbon fiber multifilament, it is necessary to buying equipment and fixture are tested again, and experimentation cost is bigger.
Utility model content
For above-described deficiency, this utility model provides a kind of carbon fiber multifilament for tension test, test suitable in the carbon fiber tensile property of multi-filament on universal testing machine, and in process of the test, do not have the phenomenon that sample comes off, reduce test period and experimentation cost.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
A kind of carbon fiber multifilament for tension test, including carbon fiber multifilament sample and winding layer, carbon fiber multifilament sample two ends are blessing portion, and blessing portion is provided with certain thickness winding layer, winding layer gluing fixing with blessing portion, winding layer adopts carbon fibre thread spiral cross winding to form.
Further, between described blessing portion and winding layer, scribble one layer of room temperature adhesive, and by coarse for the surface treatment of blessing portion.
Further, described carbon fibre thread is fixing with the end-fitting of carbon fiber multifilament sample is connected.
Further, room temperature quick-drying gelatin is scribbled outside described winding layer.
The beneficial effects of the utility model are as follows:
1. reduce experimentation cost；This utility model is applicable to the universal testing machine that general enterprises is conventional, and void does not redesign fixture or improves equipment；
2. shorten the test period；Need not making reinforced sheet specially and prepare binding material, this utility model preparation is simple and is successfully prepared rate height；
3. strengthen the reliability of data；Experimentation does not have the phenomenon that sample comes off, if desired does over again, reduce the damage to sample in process of rework.
Accompanying drawing illustrates:
Fig. 1 is this utility model population structure schematic diagram；
Fig. 2 is one of diagram of carbon fiber multifilament sample in GB/T3362-2005；
Fig. 3 is in GB/T3362-2005 the two of the diagram of carbon fiber multifilament sample；
Detailed description of the invention:
Describe in detail about exemplary embodiment of the present utility model according to following accompanying drawing.
In figure, the implication representated by sequence number is: 1-carbon fiber multifilament sample, 2-winding layer, 3-reinforced sheet.
Embodiment one: a kind of carbon fiber multifilament for tension test as shown in Figure 1, including carbon fiber multifilament sample 1 and winding layer 2, carbon fiber multifilament sample 1 two ends are blessing portion, blessing portion is provided with certain thickness winding layer 2, winding layer 2 gluing fixing with blessing portion, winding layer 2 adopts carbon fibre thread spiral cross winding to form.One layer of room temperature adhesive is scribbled between blessing portion and winding layer 2, and by coarse for the surface treatment of blessing portion.Described carbon fibre thread is fixing with the end-fitting of carbon fiber multifilament sample 1 to be connected, and winding layer 2 is outside scribbles room temperature quick-drying gelatin.
As shown in Figures 2 and 3, in GB GB/T3362-2005 " carbon fiber tensile property of multi-filament test method ", the test method of carbon fiber multifilament is specified, there are very big technological difficulties in the method in practical operation, the stretch modulus of T-800 carbon fiber multifilament is up to 2.94GPa, adopt the carbon fiber multifilament sample of patch reinforced sheet normal temperature cure binding agent bonding when being clamped on stretching-machine to carry out tension test, often occur that reinforced sheet drops off because stretching to come off with sample, and not yet there is fracture in sample, and the damage also resulting in T800 fiber in reinforced sheet process is re-pasted at sample, so that the final test data of test are well below gross data.It is bonding that this utility model adopts carbon fibre thread 2 spiral winding to intersect, carbon fibre thread 2 is wound in the blessing portion of carbon fiber multifilament sample 1 by spiral intersection is manual, winding carries out bonding and joint reason with room temperature quick-drying gelatin after completing, the blessing portion room temperature adhesive coated one layer of carbon fiber multifilament sample 1 termination, blessing portion outer surface is processed coarse, increase the bond strength with carbon fibre thread 2, it is prevented that yarn comes off in process of the test.
The foregoing is only the schematic detailed description of the invention of this utility model; it is not limited to scope of the present utility model; any those skilled in the art, without departing from this utility model design and made equivalent variations and amendment under the premise of principle, all should belong to the scope of this utility model protection.
