磨料水射流切割碳纤维复合材料的表面粗糙度试验
|
摘要
采用超高压磨料水射流技术对碳纤维复合材料进行切割试验,借助μscan激光共聚焦显微镜重构样品切口的三维表面,测得样品切口表面粗糙度;研究了扫描分辨率对表面粗糙度测量的影响,以及切割速度、样品厚度对样品切口表面粗糙度的影响规律。试验结果表明:扫描分辨率对表面粗糙度的测量无明显的影响;当切割深度较小(0～0.6 mm)时,即在切口入口处,表面粗糙度随切割深度的增大而减小,当切割深度较大(大于0.6 mm)时,表面粗糙度随切割深度的增大而增大;当样品厚度一定时,随着切割速度的增大,切口最大表面粗糙度在整体趋势上是增大的,而样品厚度的大小对表面粗糙度的影响并无明显的规律。
The cutting tests of CFRP were carried out by ultra-high pressure AWJ technology. Three-dimensional views of cutting fronts were reconstructed and surface roughnesses of cutting fronts were measured by μscan laser confocal microscopy. The influences of scan resolution on measurement of surface roughness and the influences of cutting speed and thickness of samples on surface roughness were studied. The testing results show that the scan resolution may have no obvious effects on the measurements of surface roughness. When the cutting depth is shallow(0～0.6 mm), which means at the entrance of cutting fronts, the surface roughness decreases with the increasing of cutting depth. When the cutting depth is deeper(deeper than 0.6 mm), the surface roughness increases with the increasing of cutting depth. Meanwhile, when the thickness of sample is constant, as the cutting speed increases, the overall trend of maximum surface roughness of cutting fronts increases. However, the influences of sample thickness on surface roughness have no obvious rules.
