Embodiment Construction

[0036] The following describes in detail the testing method of the mechanical properties of the impregnated fiber of the present invention with reference to the drawings and embodiments of the specification:

[0037] Such as figure 1 As shown, a testing method for the mechanical properties of dipped fibers includes the following steps:

[0038] (Ⅰ) Preparation of dipped fiber bundles and tensile specimens

[0039] (Ⅰ) Fiber bundle infiltration

[0040] The fiber bundle 3 is immersed in the matched resin and fully immersed to be uniform and without colloidal particles, and the fiber content is controlled at 80% to 90%;

[0041] (Ⅱ) Fiber bundle curing

[0042] Fix the fully infiltrated fiber bundle 3 on the support 1 and place it at 60℃~150℃ to heat for 6h~12h to solidify to form the impregnated fiber bundle;

[0043] (Ⅲ) Cut the dipped fiber bundle

[0044] Take off the dipped fiber bundle obtained after curing, cut off both ends and leave the length at 150mm~200mm to obtain the test dipp...

Abstract

The invention discloses a gum dipping fiber mechanical property testing method which comprises the steps that 1. preparing of a gum dipping fiber bundle and a stretching sample is carried out; 2. the section area of the gum dipping fiber bundle to be tested is computed; 3. the maximum load Pmax and the ductility delta of the gum dipping fiber bundle to be tested are measured; and 4. the tensile strength sigma of the gum dipping fibers is computed. A clamping piece of the gum dipping fiber stretching sample is in a rhombus shape, the gum dipping fiber bundle penetrates through the diagonal of the clamping piece, so that centering during clamping is easy, and the clamping piece has the advantages of being convenient to machine, low in cost, capable of being used repeatedly and the like. The gum dipping fiber mechanical property testing method is simple and clear in principle and easy to operate, tested data are accurate and reliable, and the performance situation of materials can be reflected really.

Description

Technical field [0001] The invention belongs to a testing method for the mechanical properties of materials, and specifically relates to a testing method for the mechanical properties of dipped fibers. Background technique [0002] At present, the application of composite materials covers almost all fields. It is a very important new material, and its performance has attracted much attention. Before the performance of structural parts is studied, the mechanical properties of the dipped fiber are generally studied. The test methods in the prior art have expensive test equipment and complicated steps. The disadvantage of poor measurement accuracy. Summary of the invention [0003] The present invention is proposed to overcome the shortcomings in the prior art, and its purpose is to provide a test method for the mechanical properties of dipped fibers. [0004] The technical scheme of the present invention is: [0005] A testing method for the mechanical properties of dipped fibers, in...
