ABSTRACT |
|
The need for high-performance
composites with superior properties tailored to the requirements of
defense and aerospace applications led to the development of hybrid
reinforcement systems in which two or more reinforcing fibers are
combined with thermoset or thermoplastic based matrix. DEBEL has
developed a series of aramid and UHMWPE based technical textiles,
multiaxial fabric and hybrid fabrics intended for the development of
lightweight helmets for fighter aircraft pilots. These are developed
to meet good impact attenuation, resistance to drop penetration and
most importantly to meet airworthiness requirements that include
windblast test. Helmet shells were fabricated using the above
fabrics in various combinations and tested for impact and drop
penetration resistance as per the MIL87174 A standard. The Helmet
shell developed from or combination of low modulus aramid fabric 62
gsm and high modulus aramid fabric 170 gsm is lightweight (328 gm)
and can withstand more than 48 Joules of impact energy. Efforts are
also being made to use thermoplastic fiber based combinations using
compression molding or injection molding to further reduce the
weight without compromising its functional properties. |
