Abstract: In order to improve the forming efficiency and automation of the equal-section spiral products, the forming process was studied. For the structural product section size and the process characteristics of the preform, the molding parameters design and process tests were performed. Equal-section preforms were prepared using advanced pultrusion process (ADP), and the preforms were twisted and filled into a spiral groove and vacuum-cured to prepare the related products. Studies have shown that the use of ADP has assitted the formation of equal-section spiral structure products with high degree of automation, compactness, and improved the appearance quality.

Key words: advanced pultrusion, spiral structure, composite material
