The composite material pipeline connecting structure comprises a first composite material pipe and a second composite material pipe, the inner pipe surface of the first composite material pipe and the inner pipe surface of the second composite material pipe are each provided with a plurality of protrusions distributed in the annular direction, and the protrusions are arranged in the axis direction of the first composite material pipe and the axis direction of the second composite material pipe; a mandrel is arranged between the first composite material pipe and the second composite material pipe, the periphery of the mandrel is sleeved with the first composite material pipe and the second composite material pipe, and the protrusions make contact with the outer shaft face of the mandrel. And adhesive layers are arranged in spaces formed among the adjacent bulges, the outer shaft surface of the core shaft and the inner pipe surfaces of the first composite material pipe and the second composite material pipe, so that the first composite material pipe and the second composite material pipe are bonded and fixed with the core shaft. By adopting the connecting structure disclosed by the invention, the connecting strength and the concentricity of the adjacent composite material pipes can be ensured.

    本发明涉及一种复合材料管路连接结构、方法及管路总成,包括第一复合材料管和第二复合材料管,第一复合材料管和第二复合材料管内管面均设有多个沿环向分布的凸起,凸起沿第一复合材料管和第二复合材料管的轴线方向设置,第一复合材料管和第二复合材料管之间设有芯轴,第一复合材料管和第二复合材料管套在芯轴外周且凸起与芯轴的外轴面接触,相邻凸起、芯轴外轴面、第一复合材料管和第二复合材料管内管面之间形成的空间设有胶黏层以实现第一复合材料管和第二复合材料管与芯轴的粘结固定,采用本发明的连接结构能够保证连接强度和相邻复合材料管的同心度。
