Manufacturing process for secondary processing of carbon/carbon composite material screen structure by laser
The invention discloses a manufacturing process for secondarily processing a carbon/carbon composite material screen structure by using laser, belongs to the field of laser processing, and relates to a manufacturing process method for secondarily processing the carbon/carbon composite material screen structure by using the laser. According to the method, aiming at the characteristics of high-density grid array holes, when the grid array holes are machined for the first time, the machining allowance removed in the second machining process is reserved, and the maximum error in the second machining process is calculated. And the same clamp and positioning method are adopted in the two times of machining, so that the machining allowance covers the error range generated by the two times of machining. And on the basis of improving a gaseous precursor transmission channel by processing the array aperture for the first time, the precision of the finally formed array aperture is ensured. According to the manufacturing process of densification treatment after laser processing of the grid array holes and secondary laser processing, the density of the carbon/carbon composite material screen mesh structure is effectively improved, various physical and chemical properties of the carbon/carbon composite material are improved, and the service performance of the carbon/carbon composite material screen mesh structure is guaranteed.
本发明用激光二次加工碳/碳复合材料筛网结构的制造工艺属于激光加工领域，涉及一种用激光二次加工的碳/碳复合材料筛网结构制造工艺方法。该方法针对高密度栅极阵列孔的特征，在第一次加工栅极阵列孔时，预留在第二次加工过程中去除的加工余量，计算在二次加工过程中的最大误差。且在两次加工中采用相同夹具与定位方法，使得加工余量覆盖二次加工所产生误差范围。在第一次加工阵列孔径提高气态前驱体传输通道的基础上，保证最终成型阵列孔的精度。提出的激光加工栅极阵列孔后致密化处理，再激光第二次加工的制造工艺，有效提高碳/碳复合材料筛网结构的致密度，改善碳/碳复合材料的各项物化性能，保证碳/碳复合材料筛网结构使役性能。
