Abstract
Disclosed are s full-form flat-knitted helmet shell preform, the preparation method, and the helmet shell, which belong to the field of helmet material technology. Two different knitting directions of the helmet shell preforms are prepared by means of longitudinal knitting and transverse knitting combined with partial knitting respectively; Meanwhile, reinforced yarn is added during the knitting process of the preforms to obtain the transversely and longitudinally knitted helmet shell preforms with reinforced yarn. The fabric structure of the preforms disclosed in this invention is a flat-knitted three-dimensional fabric with reinforced yarns, which solves the problem of low tensile strength and high elongation of flat-knitted fabrics, and solves the poor impact resistance caused by poor bonding strength between layers of helmet shells to some extent. Moreover, the method of preparing helmet shells from preforms improves production efficiency, reduces material waste, and solves the problem of poor dimensional stability.
