Tensile Properties of Curaua–Aramid Hybrid Laminated Composites for Ballistic Helmet [PDF]
Polymers, 2022 A typical ballistic protection helmet for ground military troops has an inside laminate polymer composite reinforced with 19 layers of the aramid, which are neither recyclable or biodegradable and are relatively expensive. The hybridization of synthetic aramid with a natural lignocellulosic fiber (NLF) can provide a lower cost and desirable ...
