| Résumé : |
Thermoplastic advanced composites are a rapidly growing field of advanced materials. Comprising reinforcing fibers embedded in a matrix of thermoplastic resin, these materials offer
high specific strength and stiffness and low density. In addition, thermoplastics’ high toughness makes their use appealing in applications that require energy absorption and strength after impact. Thermoplastic advanced composites also offer potential benefits of reduced cycle time and in-plant air quality for manufacture. This paper describes an initial investigation into the fabrication of a thermoplastic anti-ballistic infantry helmet. The objectives of this investigation were to assess the potential for manufacturing a high-quality helmet via thermoforming and to measure the cycle time for each processing step. The helmet construction included an inner aramid composite anti-ballistic liner and an outer carbon-fiber-reinforced thermoplastic shell. The results of this study indicate a potential for cycle time improvement using thermoplastics, but further work would be required to improve heat transfer during material pre-heating prior to forming and to automate several process steps. |
