This is a very timely review of body armour materials and systems since new test standards are currently being written,or reviewed,and new,innovative products relead.Of greatest importance,however,is the recent evolution,and maturity,of the Ultra High Molecular Weight Polyethylene fibres enabling a completely new style of system to evolve e a stackable system of Hard Armour Plates.The science of body armour materials is quickly reviewed with emphasis upon current understanding of relevant energy-absorbing mechanisms in fibres,fabrics,polymeric laminates and ceramics.The trend in on-going developments in ballistic fibres is then reviewed,analyd and future projections offered.Weak-ness in some of the ceramic grades are highlighted as is the value of using cladding materials to improve the robustness,and multi-strike performance,of Hard Armour Plates.Finally,with the drive for lighter,and therefore smaller,soft armour systems for military personnel the challenges for armour designers are reported,and the importance of the relative size of the Hard Armour Plate to the Soft Armour Inrt is strongly emphasid.染发膏怎么用

1.Background
It is extremely timely for a review of body armour materials and systems for the following reasons:
(1)The National Institute of Justice,in the US,are currently in
百家讲坛于丹the final pha of revising their standard,with NIJ 0101.07[1],expected to be issued in 2019[2].This new standard will include guidance for testing of female body armour,and a radical step change in the range of small arms ammunition ud to test future systems,as well as a signi ficant relaxation of critical blunt trauma measurements.
华为nfc(2)The UK Home Of fice has recently,in July 2017,issued a
further revision of their body armour test standard [3].
(3)The latest in the ries of Personal Armour Systems Symposia
has recently been held in Washington D.C [4].
(4)The UK MOD is soon to appoint the preferred tenderer for
VIRTUS,their completely new body armour system e an example of fit,form and function dominating evolution,especially in respon to changes in the military operational environment [5].
(5)In Australia,Victoria Police have recently appointed ADA to
supply 14,000completely new ballistic vests in 2019[6],e another example of fit,form and function dominating design,not new materials!
(6)And finally,as a warning to armour technologists keen on
developing new body armour materials,the ca against Second Chance,for lling defective vests in the early 2000s,has just been ttled,after nearly twenty years [7].The vests were constructed of a man-made fibre called Zylon which,whilst offering a very attractive t of initial proper-ties,were found to environmentally degrade to the point where the vests riously underperformed leading to tragic loss of life.This review is also extremely timely becau there has been a quantum shift in the market place in 2018.Armour solutions,bad upon Ultra High Molecular Weight Polyethylene (UHMWPE),have
