Fiberglass cloth is a kind of high-performance reinforced material with great development prospects. Fiberglass reinforced fiber-based composite materials are widely used in high-tech fields such as aviation, aerospace, transportation, energy, and environmental protection. The surface energy without surface treatment is low, the surface of the glass fiber cloth is hydrophobic, and the lack of chemically active functional groups limits the high performance of the glass fiber cloth composite material.
The surface of the glass fiber cloth is modified to change its surface structure and morphology, increase the specific surface area, improve the mechanical properties of the glass fiber cloth, and improve the oxidation resistance, in order to further improve the performance of the glass fiber cloth composite material. Mainly: The trend of the change of the average pore size is just opposite to the trend of the specific surface area. After oxidation by hydrogen peroxide, the tensile strength of the glass fiber cloth decreases by about 10% at the maximum, and the tensile strength of the glass fiber cloth increases by 14% at the maximum.
The tensile strength of the glass fiber cloth increases first, then decreases, and then increases again. The orthogonal test found that the optimal parameter combination of the glass fiber cloth is: electrolyte concentration 16%. Using a chemical method, a thin layer of nickel phosphorous alloy can be plated on the surface of the glass fiber cloth continuously and uniformly. The coating layer grows and expands in the form of corn particles. Electroless nickel plating improves the actual tensile strength of the fiber, but the elastic modulus of the fiber decreases, forming a protective film on the surface of the glass fiber cloth, which can slow down the aging speed of the glass fiber cloth and improve the anti-aging properties of the glass fiber cloth.
Using electroplating method on the surface of glass fiber cloth, he must use a layer of surface felt when he can electroplate a long life.
