The invention discloses a thermoplastic composite material L-shaped window frame structure and a compression molding process thereof, and relates to the technical field of composite material structure manufacturing. The flange rib, the skirt flange and the base flange form an oval window frame, the section of the oval window frame is of a continuous double-L-shaped structure, and the oval window frame is an oval base body formed by splicing small-curvature pre-forming split bodies symmetrically arranged on the two sides of the waist and large-curvature pre-forming split bodies symmetrically arranged at the head end and the tail end. And winding and paving a unidirectional prepreg paving layer on the surface to form a preformed body, and then performing hot-pressing curing molding. A thermoplastic composite material laminated flat plate is subjected to matrix type blanking and batch pressing to form preformed split bodies, the preformed split bodies are annularly reinforced through prepreg after being combined and assembled, and finally hot-pressing curing forming is conducted, so that fiber wrinkles can be effectively reduced, the overall strength of the window frame is guaranteed, and the manufacturing difficulty and the manufacturing cost are reduced.
一种热塑性复合材料L型窗框结构及其模压成型工艺,涉及复合材料结构制造技术领域。凸缘肋、裙部凸缘及基部凸缘组成椭圆形窗框,截面为连续的双L型结构,椭圆形窗框由位于腰部两侧对称排布的小曲率预成型分体以及位于首尾两端对称排布的大曲率预成型分体拼接成椭圆基体,表面缠绕铺放单向预浸料铺层形成预成型体后通过热压固化成型。采用热塑性复合材料层压平板通过矩阵式下料并批量压制成预成型分体,组合拼装后通过预浸料环向加强,最后热压固化成型,能够有效减少纤维皱褶,保证窗框整体强度,降低了制造难度和制造成本。
