Based on the analyzing of the influencing of temperature on the thermal and mechanical properties of the materials, a 3-D thermal-mechanical coupling models of laser sheet bending was set up in this paper. 在综合分析了材料的热物理性能和力学性能随温度变化影响的基础上,建立了板料激光弯曲成形的三维热力耦合模型。
We researched the effect of powder NBR on thermal properties and mechanical properties of phenolic resin, including the binder flowability, curing rate, bending strength and Rockwell hardness. 发现添加丁腈粉末能使树脂的固化速度加快,流动性降低,试样弯曲强度和洛氏硬度降低。
