Carbon Fiber Products Research To The Influential Factors Of Mechanical Performance

Carbon fiber product mechanical properties are greatly influenced byprocess factors in the process of test, this paper analyzes a variety of factors,including the amount of moisture, humidity, dry conditions, the fibers expanddegree, sample preparation time and the part time dipping, The resultsindicate that the fiber mechanical properties are greatly influenced by humidity,generally,Need to control the humidity of the indoor environment, at least below40%, it suggest to dry fiber to water treatment when environmental humidity isover40%，treatment conditions is:105℃,dry1h. Resin was not dried becauseof Low viscosity resin seriously affecting the tensile strength of carbon fiber. Theappropriate fiber width is good for strength test results. Carbon fiber impregnatedwith glue sample preparation time control in25minutes, Sample preparationprocess to ensure proper tension. The tensile strength of carbon fiber was affectedby Sample preparation process to strengthen the sheet thickness, uniformity, andthe choosing of curing adhesive etc. Generally, need to select the cardboard thestrength of the adhesive curing should be greater than the tensile strength of thefiber. Fiber normal sample preparation and sample test Rapid little impact on theultimate strength, and it can be applied to process adjustment. Appropriateamount of adhesive on the surface of carbon fiber have a greater contribution fortensile strength test results. Industrial production of tensile modulus test can beused to contact amplify, Easy operation and test more accurate...
