METHOD FOR PREPARATION OF SAFETY HELMET WITH HYBRID COMPLEX MATERIAL AND SAFETY HELMET THEREOF

摘要

The present invention relates to a kind of methods for manufacturing the helmet shell first is that lightweight, excellent impact strength, it is simple in process of production, using be economical with the existing helmet compared with and one high by the hybrid composite material that forms of a fiber reinforced composite material is laminated-the present invention relates to a kind of methods to use a hybrid composite material for manufacturing a helmet, the helmet obtained therefrom, including method: using a thermoplastic resin mould a head-shaped liner (21); At least two layers of a laminating step of hybrid composite material 22 is laminated, is formed by the composite material 222 of film of fiber reinforced composite material 221 and highly elastic fiber enhancing is laminated on the liner 21 for fashioning into a first shape; Hybrid composite material 22, which is placed in the removable metal mold 12 being made of multiple sheet metals 121 and an individual metal gasket 23, is placed on liner 21 and a curing schedule, and wherein resin is left in a hot room under stress. ;Therefore, it is provided with a safety cap (1) for the weight and excellent impact strength that have the effect of that a thin thickness, one are relatively light, more particularly to change initial impact performance and maximum safety energy and its manufacturing method.
