STUDY ON THE PREFORMING TECHNOLOGY OF ADVANCEDPULTRUSION FOR HAT STIFFENER

Abstract

Abstract: For hat stiffener′s advanced pultrusion, the preformed deformation process was analyzed. Then, design and manufacturing preformed molds, analysis and formulation of preforming process were carried out to avoid folding and splitting of prepreg inpreforming process which with continuous bending deformation. Experimental verification shows that the stiffener has excellent surface quality. No wrinkles and other defects in the R area, which can meet the requirements of the product, and lay the foundation for the advanced pultrusion manufacturing hat stiffener.

Key words: advanced pultrusion, preforming, hat stiffener, resin flow
