摘要
连续碳纤维(CCF)增强复合材料具有轻质高强等优异性能,结合3D打印技术在船舶建造行业具有广阔应用前景,其中丝材制备是目前亟待解决的关键技术.采用正交实验法,以树脂进给量(A)、外包裹结构件加热温度(B)和收卷速度(C)作为研究因素,并考虑丝材制备工艺参数之间的交互作用,根据正交实验表进行连续碳纤维增强聚碳酸酯(CCF/PC)丝材制备实验,以连续碳纤维丝材的单位直径、拉伸强度性能作为衡量指标.通过极差分析和方差分析,确定了使CCF/PC丝材整体性能最优的工艺参数组合:树脂进给量(A)为3挡、外包裹结构件加热温度(B)为270℃、收卷速度(C)为150mm/min.在最优工艺参数下制备的丝材单位直径为0.594mm,拉伸强度高达451.07MPa.研究结果可为连续碳纤维增强复合材料在船舶建造行业的应用提供理论依据.
Continuous carbon fiber(CCF)reinforced composite materials have excellent properties such as light weight and high strength,and have broad application prospects in the shipbuilding industry when combined with 3D printing technology.Among them,filament preparation is a key technology that urgently needs to be solved at present.Using orthogonal experimental method,the interaction between the process parameters of filament material preparation is considered with resin feed rate(A),heating temperature of outer wrapping structural components(B)and winding speed(C)as the research factors.According to the orthogonal experimental table,the preparation experiment of continuous carbon fiber reinforced polycarbonate(CCF/PC)filaments is conducted with the unit diameter and tensile strength performance of continuous carbon fiber filaments as the measurement indicators.Through range analysis and variance analysis,the optimal process parameter combination for achieving the best overall performance of CCF/PC filaments is determined:resin feed rate(A)is 3 gear,heating temperature of outer wrapping structural components(B)is 270℃,and winding speed(C)is 150 mm/min.The unit diameter of the filament prepared under the optimal process parameters is 0.594 mm,and the maximum tensile strength is 451.07 MPa.The research results can provide a theoretical foundation for the application of continuous carbon fiber reinforced composite materials in the shipbuilding industry.
