Abstract
The invention discloses glue solution for testing tensile property of multi-filament, which is composed of TDE-85 epoxy resin, powdered Diaminodiphenyl Methane (DDM) and acetone, wherein the mass ratio of the TDE-85 epoxy resin to the powdered DDM to the acetone is 100 to (30-50) to (80-150). Test and analysis of filament bundle dipped by the glue solution disclosed by the invention show that partial breakage of carbon fiber multi-filament can be effectively avoided, the performance of the overall filament bundle can be fully displayed, and test result is steady.
Description
Technical field
The present invention relates to a kind of glue for the tensile property of multi-filament test, particularly the glue of 12k tensile property of multi-filament test.
Background technology
Carbon fiber is widely used in the fields such as Aero-Space, national defense construction because the excellent specific properties such as its high specific strength, high ratio modulus, heat-resisting, corrosion-resistant, endurance, creep resistant are used as a kind of reinforcing material, wherein, being most widely used of polyacrylonitrile-based carbon fibre, output is also the highest.The 12k multifilament is large because of its tow, and cost is relatively low, and range of application at home is more and more wider, and demand constantly increases.But, each carbon fiber manufacturer and research unit, the test sign for the 12k tensile property of multi-filament can't stably reach the index that producer announces, and is especially obvious with Japanese T700 series 12k.At present, the mechanical property that can't the performance test means accurately characterizes this carbon fiber that producer announces, TENSILE STRENGTH 〉=the 4900MPa of the T700 series 12k carbon fiber multifilament of announcing such as: manufacturer, and China entering factory's test and can not reach this index T700 series 12k carbon fiber multifilament.
Due to international community's every country holding in close confidence for the carbon fiber correlation technique, find by searching document, usually the resin of test carbon fiber tensile property of multi-filament use mainly contains glycidol ether based epoxy resin and cycloaliphatic epoxides, curing agent mainly contains amine curing agent, acid anhydrides and latent curing agent, find after deliberation, use glycidol ether based epoxy resin and amine curing agent that Japanese T700 series 12k carbon fiber is detected, can not stablize and reach the technical indicator that producer provides, for this reason, the present invention proposes a kind of new glue.
At present, mainly there are following problem in sample preparation and test:
(1) test can not guarantee the integral body performance of carbon fiber tensile property of multi-filament preferably with glue;
(2) the TENSILE STRENGTH test can not be stablized the product index value that reaches generally acknowledged in industry: 〉=4900MPa.
Summary of the invention
The objective of the invention is to have proposed a kind of glue for the tensile property of multi-filament test for overcoming in prior art for the not high and stable not deficiency of T700 series 12k carbon fiber multifilament test index.
The present invention is comprised of TDE-85, Powdered DDM and acetone, and the quality proportioning of TDE-85, Powdered DDM and acetone is 100: 30～50: 80～150.
By analysis, causing the bad main cause of test result is that in test, the carbon fiber multifilament is not whole fracture, and is often the part fracture, and the performance of whole synnema is not brought into play, adopt this glue to carry out test analysis, the performance of whole synnema is given full play to and test result is stablized.This method can be stable the assurance test result, satisfy the technical indicator that producer provides.Test comparison sees the following form, concrete test result (extensometer is used in the elastic modelling quantity test: INSTRON2630-111) as follows:
