Abstract

Abstract Fused filament fabrication is a promising additive manufacturing technology and an alternative to traditional processes for the fabrication of polymer and fiber-reinforced polymer composites. In this work, the effects of process parameters such as layer thickness, infill density, and infill pattern on the ageing and free vibration characteristics of three-dimensional printed composites were investigated. It was observed that the water absorption rate is higher in acrylonitrile butadiene styrene (ABS) printed specimens compared to carbon fiber reinforced acrylonitrile butadiene styrene (CF/ABS) specimens due to the effect of carbon fiber which acts as a strong hydrophobic material. The free vibration characteristic of the printed composite specimen is found as per American Society for Testing Materials standards. From the results, it is found that the 5 % addition of carbon fiber, hexagonal pattern, and 0.30 mm layer thickness show an increase in the vibration behaviour of the composites compared to the specimen printed without reinforcement. Experimental modal analysis was carried out on a cantilever beam-like sample and revealed that the addition of fiber has enhanced natural frequencies and damping ratio.

工艺参数对熔融长丝制备纤维增强聚合物复合材料老化及自由振动特性的影响

摘要熔融长丝制造是一种很有前途的增材制造技术，是传统聚合物和纤维增强聚合物复合材料制造工艺的替代方案。本文研究了层厚、填充密度和填充方式等工艺参数对三维打印复合材料老化和自由振动特性的影响。结果表明，由于碳纤维作为强疏水材料的作用，ABS(丙烯腈-丁二烯-苯乙烯)打印样品的吸水率高于碳纤维增强丙烯腈-丁二烯-苯乙烯(CF/ABS)样品。根据美国材料试验学会的标准，确定了打印复合材料试样的自由振动特性。结果表明，碳纤维添加量为5%、六角形图案和0.30 mm层厚时，复合材料的振动性能比未增强的样品有所提高。对悬臂梁样试样进行了模态分析，结果表明纤维的加入提高了固有频率和阻尼比。
