|Abstract: ||Purpose – The purpose of this paper is to ascertain the stab resistance characteristics of a series of planar and articulated laser sintered (LS) samples,
in accordance with the United Kingdom Home Office Scientific Development Branch (HOSDB) Body Armour Standard – Publication 39/07.
Design/methodology/approach – A series of LS planar samples were manufactured using an EOS P100 Formiga system, manufactured from 100 per
cent virgin or a 50:50 mix of recycled and virgin Nylon (PA2200), ranging in thickness from 1-10 mm. All planar samples were stab tested to the HOSDB
knife-resistance (KR) level one impact energy of 24 Joules, using an in-house manufactured HOSDB guided rail drop test impact rig and standardised
knives. Penetration through the underside of each sample was measured and recorded. These results were then used to develop an articulated, additive
manufactured (AM) scale textile – LS from a 50:50 mix of recycled and virgin PA2200 powder. These samples were then tested using the
aforementioned impact rig and stab impact energy.
Findings – The research demonstrated that while virgin PA2200 sample required a minimum thickness of 8mm to achieve stab-resistance below the
HOSDB maximum penetration limit of 7 mm, this figure can be reduced to 5.6mm when manufacturing LS planar samples from a 50:50 mix of virgin
and recycled PA2200. Results from stab testing the articulated samples indicated a successful AM textile-like design, with a maximum knife penetration
of 1.6mm – below the 7mm HOSDB limit.
Originality/value – The paper describes a unique application of AM technologies for the manufacture of high-performance stab resistant AM textiles.
