Manufacturing of ballistic helmets

6 Helmet material preparation process (a) Prepreg roll, (b) Petal marking process, (c) Manual cutting, (d) Dome formation. 

NC cutting table, flatbed die cutting or rotary die cutting tools. However, the huge investment needed for this may also incur production costs. 

7 Helmet formation process (a) Helmet cone, (b) Hot press process, (c) Helmet formation, (d) Edge trimming. 

The external helmet surface has a rough finish, and the edge will be trimmed before the helmet is forwarded to the spraying bay. 

Marissen et al. (2010) have explored a new approach in the production of highly three-dimensionally craved composite helmet products using continuous
