Abstract

The invention discloses a preparation device of a plasma-modified glass fiber. The preparation device comprises a pulse power source device, a discharge device and a measuring device, wherein the pulse power source device comprises a pulse power source and a voltage regulator connected with the pulse power source; the discharge device comprises a high-voltage electrode and a ground electrode; the lower surface of the high-voltage electrode is provided with a unilateral countercheck medium; the measuring device comprises an oscillometer. The preparation device can be used for solving the problem that the modified glass fiber prepared by an existing modification method is low in heat resistance and the composite material prepared by the modified glass fiber can not adapt to use environments with relatively high temperature. The invention also discloses a method for peparing the plasma-modified glass fiber. The method comprises the following steps: step 1, preprocessing the glass fiber; step 2, performing plasma modification on the preprocessed glass fiber by use of the preparation device of the plasma-modified glass fiber.

Description

technical field [0001] The invention belongs to the technical field of novel composite materials, and relates to a preparation device for plasma modified glass fiber. The invention also relates to a preparation method of the plasma modified glass fiber. The invention also relates to the application of the plasma modified glass fiber prepared by the method. Background technique [0002] Alkali-free glass fiber is usually used as a reinforcing material for epoxy resin. Composite epoxy resin has a series of advantages such as good insulation performance and high mechanical strength, so it has a wide application prospect in the electrical field. However, due to the structure of the glass fiber itself, the bonding between it and the epoxy resin matrix is ​​poor, so it needs to be surface treated to make it easier to bond with the epoxy resin, thereby improving the performance of the composite material. [0003] At present, there are many ways to modify the surface of fiber mate...
