摘要
为了揭示激光切割碳纤维复合材料(CFRP)时材料对激光能量的吸收和传递机理,分别建立了激光同向切割单丝排列CFRP的三维有限元模型、丝-束直径比例三维模型和纤维-树脂两相三维模型。模拟结果表明,随着丝-束直径比例的减小,切缝宽度从229.45 μm降至95.60 μm,热影响区(HAZ)宽度从172.08 μm降至156.79 μm。试验与模拟结果基本一致,切缝宽度和HAZ宽度的误差分别为5.97%和1.13%。
Abstract
In order to reveal the mechanism of energy absorption and transfer of materials in laser cutting of carbon fiber reinforced plastics (CFRP), a three dimensional finite element model for parallel laser cutting of single-fiber arranged CERP, a three dimensional fiber-spot diameter ratio model and a three dimensional fiber-resin double phase model are established, respectively. Numerical simulation results show that, with the decline of fiber-spot diameter ratio, the kerf width decreases from 229.45 μm to 95.60 μm, while the width of the heat affected zone (HAZ) decreases from 172.08 μm to 156.79 μm. The experimental results agree well with the simulation results, and the errors for the kerf width and the HAZ width are 5.97% and 1.13%, respectively.
