preparation example Construction

[0032] A preparation method of titanium dioxide nanorod modified carbon cloth reinforced resin-based composite material, comprising the following steps:

[0033] Step 1: Inoculation of TiO on the surface of carbon cloth fiber 2 seed layer.

[0034] In parts by volume, take 100 parts of absolute ethanol in a beaker, add 1-5 parts of concentrated hydrochloric acid dropwise, and stir well. Add 5-20 parts of butyl titanate dropwise into the prepared acidic solution, stir for 30 minutes and then let stand for 1 hour to form TiO 2 Sol. The carbon cloth washed with acetone was soaked in the sol for 5 minutes to inoculate, the inoculation process was repeated 1-5 times, and then dried in an oven at 100°C for 10 minutes to obtain a pretreated carbon cloth.

[0035] Step 2: Hydrothermal growth of TiO 2 Nano stave.

[0036] Arrange the pretreatment carbon in the mixed solution of deionized water: concentrated hydrochloric acid: hydrogen peroxide: butyl titanate = (20-30): (10-20): (...

Abstract

The invention discloses a preparation method of a titanium dioxide nanorod modified carbon cloth enhanced resin matrix composite material. The preparation method comprises the following steps: firstly soaking commercial carbon cloth by virtue of an acetone solution at the room temperature so as to remove a sizing agent on the fiber surface of the carbon cloth, inoculating TiO2 crystal seeds to the surface of the fiber surface of the washed carbon cloth by virtue of TiO2 sol, and growing a TiO2 nanorod on the fiber surface of the carbon cloth by virtue of a hydrothermal growth treatment; after the reaction, adequately washing the modified carbon cloth, and drying; and preparing a multi-scale carbon cloth enhanced resin matrix composite material by taking the modified carbon cloth as an enhancement body. The titanium dioxide nanorod modified carbon cloth mixed body multi-scale enhanced resin matrix composite material has the beneficial effects that the tensile strength is increased by 21%-84%, the three-point bending strength is increased by 30%-89%, the friction coefficient is stable and is maintained as 0.1, the wear rate is decreased by 25%-56%, and the enhancement of a titanium dioxide nanorod modified carbon cloth enhanced body to a matrix composite material and the wear reduction and rear resistance of the titanium dioxide nanorod modified carbon cloth enhanced body applied to wet friction materials are adequately embodied.

Description

technical field [0001] The invention belongs to the field of wet friction materials, and in particular relates to a method for preparing a titanium dioxide nanorod modified carbon cloth reinforced resin-based composite material. Background technique [0002] Carbon cloth is widely used in engineering materials based on its outstanding friction and lubrication properties, high specific strength, low density and orderliness. However, the surface of carbon cloth fiber is inert, does not have a rich network branch structure, its performance is poor in the direction perpendicular to the fiber, and the interface with the resin is not ideal, which limits the use of resin-based composite materials in harsh environments and environments to a certain extent. applications in special fields. Therefore, appropriate modification treatment is carried out on the carbon cloth fiber to improve its bonding strength with the resin matrix and further expand its application field. [0003] The ...
