Description
Technical Field
the invention relates to the technical field of composite material performance testing, in particular to an improved test device and a test method for the shear performance of a composite material base/fiber interface.
background
At present, the test methods for measuring the shearing performance of the composite material base/fiber interface mainly comprise four methods: fiber breakage test, fiber pull-out test, fiber press-in test, and microsphere debonding test. Among them, the fiber drawing test is one of the most direct methods for obtaining the interface parameters, and a plurality of interface parameters can be obtained by one test.
the monofilament drawn sample preparation process was as follows: the treated fibers or protofilaments are singly and vertically fixed in the center of a silicone rubber pad (arranged on a die carrier). A drop of epoxy was injected onto the pad with a syringe and laid flat. After the fiber is solidified for twenty-four hours at room temperature, the fiber on the upper surface of the resin is cut off, a thin plastic tube is placed on the fiber, a thin layer of red resin is poured, and then the colorless same resin is poured, so that the color contrast is strong, and the fiber embedding length can be conveniently measured. The specimens were post-cured for three hours at 50 ℃. (very careful sample preparation, cut resin top surface fiber as smooth as possible. resin due to the resin to fiber infiltration, resin along the fiber up-run phenomenon, try to reduce) in the fiber electronic strength instrument, at a speed of 2mm/min tensile sample. The embedded length of the fiber is measured by a microscope, and the morphology of the drawn monofilament is observed.
At present, the following defects generally exist in a single fiber extraction test method:
1. The fibers are difficult to ensure to be vertical, and the measured interfacial debonding force has large deviation, so that the obtained interfacial shear strength is inaccurate;
2. The test device needs higher rigidity, namely, the connection part of the fiber and the resin is easy to have torque and bending moment in the process of transportation and clamping;
3. The fiber embedding depth is difficult to control strictly, and the reason why the fiber embedding depth needs to be controlled is as follows:
in the case of single fiber extraction tests, to ensure that the fibers are completely extracted during the test, the control of the embedding length of the resin matrix for the fibers is critical for the preparation of the test specimen, and an excessively long embedding length causes the fibers to break during tension rather than being extracted from the resin matrix, so the embedding length must be less than the critical fiber extraction length, the embedding depth L has the following relationship [1] with the fiber strength σ f and the interfacial shear strength τ i:
Wherein r is the diameter of an individual fiber. The formula shows that a critical value of the fiber embedding depth exists, and the fiber is broken in the stretching process when the certain embedding depth is exceeded; otherwise, the fiber is pulled out. The radius r of the individual fibers of the carbon fiber is usually about 3.5 μm, the strength is usually about 3.5GPa, and the interfacial shear strength is usually about 60MPa, so the initial estimation of the critical fiber embedding length is about 100 μm. The embedding depth can not exceed 50 μm considering the influence of thermal expansion and the large fiber strength dispersion during the resin curing process.
In summary, it is necessary to provide a testing apparatus and a testing method to solve the problem of measuring the shear property of the matrix/fiber interface of the composite material.
