碳纤维增强复合材料低温冷风磨削试验研究
Experimental Study on Cryogenic Cold Air Grinding of Carbon Fibre Reinforced Plastics
摘要
Abstract
Cryogenic cold air and dry room temperature grinding experiments were carried out for unidirectional CFRP using SD80N100B diamond wheel.The influences of cryogenic cold air and grind-ing parameters on material grinding performance were discussed.The morphologies of ground surface and sub-surface damage were observed by scanning electron microscope and ultra-depth field optical microscopy and factors influenced on surface roughness were analyzed.The results show that,com-pared with dry grinding conditions,cryogenic cold air grinding results in larger grinding force,lower surface roughness.Under cryogenic cold air and dry room temperature grinding conditions,the maxi-mum grinding force and minimum surface roughness are obtained when ground surface perpendicular to the fibres lengthen direction.关键词
