Additive manufacturing forming method for continuous fiber reinforced ceramic matrix composite perpendicular to printing plane
The invention belongs to the technical field of composite material forming, and relates to a continuous fiber reinforced ceramic matrix composite material additive manufacturing forming method perpendicular to a printing plane. The method comprises the steps that firstly, continuous fibers are fixed in the direction perpendicular to a printing plane; mixing and ball-milling the ceramic powder, water, a dispersing agent and a binding agent to obtain uniformly dispersed mixed slurry; then, a composite material blank is printed through additive manufacturing equipment; and then drying and carbonizing. Then dipping, curing and sintering are carried out, dipping, curing and sintering are repeatedly carried out, densification treatment is carried out, and finally the composite material is obtained. According to the forming method, preparation of third-dimensional continuous fibers introduced into the two-dimensional plane matrix in the composite material is achieved, and the forming method is suitable for additive manufacturing preparation of various continuous fiber reinforced ceramic matrix composite materials perpendicular to the printing plane in the space.
本发明属于复合材料成型技术领域，涉及一种与打印平面垂直的连续纤维增强陶瓷基复合材料增材制造成型方法。本发明首先将连续纤维以垂直于打印平面的方向固定；然后将陶瓷粉体、水、分散剂、粘结剂混合球磨，得到分散均匀的混合浆料；接着利用增材制造设备打印复合材料坯体；再经过烘干、碳化。之后进行浸渍、固化、烧结，并重复进行浸渍、固化、烧结对其进行致密化处理，最终获得复合材料。本发明的成型方法实现了复合材料中二维平面基体引入第三维度连续纤维的制备，适合各种在空间中与打印平面垂直的连续纤维增强陶瓷基复合材料的增材制造制备。
