Processing custom Carbon Fiber Telescopic Pole expansion combination of straight pipe.
Product synopsis
Carbon fiber sleeve (CB) By the high quality carbon fiber yarn woven,Carbon fiber is a kind of excellent
mechanical properties of new materialsThe proportion of material, it is less than steel A quarter, the tensile strength of carbon fiber resin composite materials are generally in 3500 mpa In order to On the
steel is on the 7 ~ 9 Times, it has strong flexibility, resistance to high temperature, the proportion of light,
etc.The casing can be Used to set some irregular surface of wire, cable or hose, and good stability, high
torsional strength.
Carbon fiber is widely used in the car, aerospace, military industry and other high-tech fields.

Chemical properties
Due to the raw material, the modulus, strength and the degree of different heat treatment temperature,
the characteristics of different carbon fiber, the former hard and brittle is often used in composite material,
soft and supple commonly used in the textile;The latter is used for engineering materials.Because of more
and more than the application of carbon fiber properties, the urgency of the tensile properties of carbon fiber strength test before us.Finished strong stretching performance belongs to destructive test, the
sample without recoverability, after again for carbon fiber separation become single fiber is very fragile,
therefore in the process of each test, need careful, patient and do not cause damage to sample before
test.General test need to be technical index is the average of the CV value, etc.The tensile properties
of the carbon fiber monofilament and multifilament method test points.Carbon fiber separation become
single fiber is very fragile, low shear strength, fracture will be affected by any carelessness, therefore in
the process of each test, need careful, patient and do not cause damage to the sample.Single fiber
strength and performance test by using paper box fixed sample, usually, of course, does not rule out
other methods.Single fiber strength and performance test can test must be used with high strength and
high modulus fibers of carbon fiber, powerful instrument.Paper box method of fixed sample, shearing test
samples and the appropriate length of the carbon fiber with steel needle along the fiber direction its
separation, make the test samples fluffy facilitate extraction.To serve them with sample plate sample, in
order to guarantee the accuracy of the measured results, can't cause any damage to carbon fiber.Made
backing paper very troublesome foreign standards, in the process of test I use the computer mapping to
find a simple and feasible method.Take about 0.1 mm thick paper to do substrate;Profiling Word
according to the size of figure 1, create a suitable size box, copy the full A4 paper to print (figure 1 is 25
mm separation stretch size. If a 50 mm separation stretching, cutting tangent length should be doubled);
Ruler and tangent anastomosis after cutting blades for the solid part along the tangential cutting will be
cut, and then the two end with double-sided tape 5 mm wide;Extraction separation of single carbon fiber
test samples and placed along the center dotted line, and double sided tape fixed.Can also use melted
rosin, single carbon fiber "welding" on the paper box, the "spot" have the effect of fixed single carbon
fiber (trials show that: the "welding" way no double-sided tape and fixed way to use, and gripped sample
to leave "spot");With paper article 8 ~ 10 mm wide, covering double-sided tape in the direction of the
tangential cutting width and the end of the test sample, shear along the shear line, separated into fixed
sample under test in a single paper box.Note: carbon fiber sampling is difficult, especially after treatment
of carbon fiber, very thin, is also difficult to distinguish a root or two, according to the experiment curve
contrast to judge if the record the curve slope is significantly greater than the other sample is likely to be
two fiber, can take samples with a magnifying glass to cooperate when necessary.
