A unibody molding method employed to manufacture continuous fiber reinforced composite riot helmet shells

摘要：

　　The conventional laminated composite helmet shells are with some structural defects, such as forming wrinkle or using discontinuous reinforcing fibers.In order to improve the protective level of the riot helmet, a unibody molding method is required.Angle interlock fabrics can be molded into 3-dimensional structural shape (3D), without forming wrinkle and cutting the fabric.In this paper, a vacuum assisted resin transfer molding method (VaRTM) was employed to manufacture the angle interlock fabric reinforced composite helmet shell in the negative mould.By comparing the morphology and anti-impact properties of this unibody molding helmet with the laminated helmet, it is found that the proposed molding method is feasible.
