[0087] (1) Establishment of geometric model

[0088] A cuboid with a size of 10mm×10mm×1.1mm is set to represent the geometric model of the simulated release agent. In the layer option, set the top 0.1mm as the release layer. Set the carbon fiber size of a single 0° alignment as a long cylinder with a radius of 0.2mm and a height of 10mm. Using the array option, a single carbon fiber is distributed along the x-axis direction into 10 identical long cylinders, each with an interval of 1mm. In the same way, when setting a single 90°-aligned carbon fiber of the same size, use the array option to distribute a single carbon fiber along the y-axis direction in 10 identical long cylinders, each with an interval of 1mm. The carbon fibers arranged in the 0° direction and the 90° direction are selected to be "merged", so that the two are closely connected, simulating the vertical weaving method of the actual resin-based carbon fiber composite material, and evenly distributed in the mat...

Abstract

The invention relates to the field of pretreatment of glued carbon fiber composite materials in aerospace and automobile industries, in particular to a method for simulating temperature field in a carbon fiber material release agent based on laser cleaning stripping. The method comprises the following steps: 1) establishing a three-dimensional transient temperature field model through COMSOL; 2) scanning the to-be-detected carbon fiber composite material through a three-dimensional laser scanner, constructing a geometric model of the carbon fiber composite material, and planning a moving pathof laser in the geometric model through a COMSOL model development module; 3) introducing a pulse laser heat source to establish a heat source model; 4) setting material parameters of the geometric model of the carbon fiber composite material; 5) setting initial conditions and boundary conditions of the geometric model of the carbon fiber composite material; and 6) dividing different grids for thegeometric model of the carbon fiber composite material, and obtaining the relationship between the laser scanning speed and the temperature field after completion through a COMSOL analysis module. According to the invention, COMSOL software is utilized to be suitable for numerical simulation of temperature field distribution of laser cleaning of the carbon fiber resin matrix composite material.

Description

technical field [0001] The invention relates to the field of pretreatment of bonded carbon fiber composite materials in aerospace and automobile industries, in particular to a method for simulating the temperature field in a release agent based on laser cleaning and stripping carbon fiber materials. Background technique [0002] Carbon fiber composite materials are widely used in various aircraft manufacturing fields. In order to obtain strong bonding strength, it is necessary to pre-treat the surface of carbon fiber composite materials to remove excessive release agents and impurities on the surface. For the pretreatment of the coating, methods such as grinding, chemical corrosion, and mechanical polishing are usually used. Such methods have many shortcomings in subsequent cleaning and processing efficiency. Therefore, people are gradually turning their attention to a new surface pollutant treatment technology - laser cleaning technology. Laser cleaning technology refers t...
