Embodiment 1

[0046] The selected fibers are carbon fibers, and the coating precursor solution is a silicon carbide precursor solution with a concentration of 35%. The selected carbon fibers are fully impregnated in the SiC precursor solution. Finally, the impregnated carbon fibers are taken out and evenly wound on the centrifugal drum of the desizing device. Adjust the rotational speed of the centrifugal drum to 800r / min, desizing until the silicon carbide precursor solution no longer sticks between the fibers. The desized fibers are taken out and added to the beam expander to expand the fiber bundle to a 10cm single-layer fiber, and evenly wind it onto the fiber collection drum. Put the fiber collection drum wound with the pretreated fiber on the conveying roller in the airtight chamber, and feed in nitrogen gas with a temperature of 15° C. as a protective gas from the air inlet of the airtight chamber. The laser wavelength is selected as 355nm, and the output power is 10W.

Embodiment 2

[0049] The selected fibers are silicon carbide fibers, and the coating precursor solution is an alumina precursor solution with a concentration of 60%. The selected SiC fibers were fully impregnated in the alumina precursor solution. Finally, the impregnated silicon carbide fibers are taken out and evenly wound on the centrifugal drum of the desizing device.

[0050] Adjust the rotational speed of the centrifugal drum to 1200r / min, desizing until the alumina precursor solution no longer sticks between the fibers. The desized fibers are taken out and added to the beam expander to expand the fiber bundle to a 50cm single-layer fiber, and evenly wind it onto the fiber collection drum. Put the fiber collection drum wound with the pretreated fiber on the transfer roller in the airtight chamber, and feed carbon dioxide with a temperature of 25° C. as a protective gas from the air inlet of the airtight chamber. The laser wavelength is selected as 10.6um, and the output power is 70W...

Embodiment 3

[0052] The selected fibers are alumina fibers, and the coating precursor solution is a silicon carbide precursor solution with a concentration of 80%. The selected SiC fibers were fully impregnated in the alumina precursor solution. Finally, the impregnated alumina fibers are taken out and evenly wound on the centrifugal drum of the desizing device.

[0053] Adjust the rotation speed of the centrifugal drum to 1500r / min, desizing until the silicon carbide precursor solution no longer sticks between the fibers. Take out the desized fibers and add them to the beam expander to expand the fiber bundles to a single layer of 20cm fibers and wind them evenly onto the fiber collection drum. Put the fiber collecting cylinder wound with the pretreated fiber on the conveying roller in the airtight chamber, and pass into the argon gas with a temperature of 50° C. as a protective gas from the air inlet of the airtight chamber. The laser wavelength is selected as 1064nm, and the output po...

Abstract

The invention discloses an equipment and method for laser irradiation guiding fiber coating precursor coating, including a fiber desizing device, a fiber beam expanding device and a laser irradiation device; After irradiation, the fiber can be heated and compounded with thermoplastic or thermosetting materials, which can enhance the comprehensive mechanical properties of carbon fiber composite materials, and the annealing and curing can be completed quickly by passing in a cooling inert protective gas.

Description

technical field [0001] The invention relates to equipment and methods for laser irradiation guiding fibers to coat precursor coatings, and belongs to the technical field of fiber manufacturing. Background technique [0002] Coating on the surface of fibers is an important method for composite modification of fibers. The coating can effectively improve the fiber interface and make up for the defects on the fiber surface, so that the fiber has higher mechanical properties such as strength and modulus. The coating can also enable the fiber to have properties that it did not have originally, such as: insulating properties, electrical conductivity, high temperature resistance, hydrophobic properties, etc. Moreover, the coating can effectively protect the core material of the fiber, so that the use range of the fiber is wider and the service life is longer. [0003] At present, the common fiber coating methods are as follows: chemical vapor deposition method (CVD method), chemic...
