Abstract

A material which provides puncture resistance whilst still retaining flexibility and reduced weight consists of a substrate material and a ceramic loaded composite applied thereto. The composite may comprise particles of hard ceramic, especially boron carbide, of largest dimension less than 500 um, and a carrier of thermoplastic polymer, water-soluble (meth)acrylic acid or acrylamide polymer, or natural or synthetic rubber. It may coat or impregnate the substrate material; alternatively it may be applied to fibres which are woven or knitted to form a fabric.

Description

2353960 PUNCTURE RESISTANT MATERIAL The present invention relates to
puncture resistant materials and in particular to materials suitable for the manufacture of protective clothing including gloves.
Puncture resistant materials have been used for many years to provide protection to the human or animal body against sharp objects and also to provide a material barrier to protect 'an object against damage from sharp objects such as use in shields or walls.
Historically puncture resistance has been required to protect soldiers, and objects in general, against swords and spears on the battlefield and the requirement is just as important in the military field today. In addition to Lhe military there is also a growing requirement for personal protection against various attacks, such as from knives and animal bites, in particular for organisations such as the police force.
Despite the large requirement for such puncture resistant materials the actual design of the materials and the mode in which they offer protection has changed little over the years. At present there are two main methods used for protection, the protective clothing or material either comprises a solid plate of material such as steel or a ceramic, usually referred to as armour, or the clothing or material comprises a large number of layers of a partial-Ly resistant material such as leather or Kevlare) (an aramid fibre), the later mainly being used for protection against knife attack or animal bites.
The problem with the above methods and the materials used is that the finished garments, although providing the required protection, are often heavy and inflexible and therefore hot and uncomfortable to wear. They are also often difficult to form into complex or lightweight structures. This often leads to an individual choosing not to wear the garment or use the material with the associated risk of injury. A further result of these problems, particularly with respect to the inflexibility of the materials, is limitations on the uses of the materials.
2 There are many situations where a light weight flexible material is required. One example of many is in clothing which for the avoidance of doubt shall be defined as including gloves, hats and footwear. Here an individual may require to wear gloves or other clothing in order to protect themselves from sharp objects or foreign materials Such situations are very wide ranging and include gardening gloves for protection against thorns, diving suits for protection against sharp or abrasive objects and bites such as from sharks and medical gloves for protection against needles. At present this protection can only be achieved by using thick, inflexible or heavy materials with the resultant loss of dexterity and in practice a trade-off is made between increased dexterity and reduced protection with the associated increase in risk.
one use where it is particularly important to maintain dexterity whilst providing absolute protection against puncture,.,, -.and. the resulting ingress of foreign materials, is in relation to glove' boxes and in particular to glove boxes used in radioactive applications. In this situation the gloves are used as abarrierl- against potentially harmful materials and should the gloves be punctured the user would be apen to attack by those harmful materials. Despite this a level of dexterity is still required and as such the level of puncture resistance cannot be maximised.
The object of the present invention is therefore to develop a material which provides puncture resistance whilst still retaining flexibility and reduced weight.
Accordingly, the present invention provides a puncture resistant flexible material comprising a substrate material and a ceramic loaded composite applied thereto.
The present invention also provides a method of manufacturing such a puncture resistant flexible material.
The applicant has found that suitable ceramic loaded composites can be formed by using an organic carrier mixed with hard ceramic powders. Such a ceramic loaded composite is then capable of being 35 applied to a substrate material. The composite of substrate 3 material and ceramic loaded composite applied thereto is then allowed to dry forming a coating on the substrate material which is both flexible and puncture resistant.
In the above application the hard ceramic powder hinders the penetration of the sharp object, whilst the organic carrier holds the hard ceramic powder particles to the substrate and also provides a flexible matrix with the particles.
An optimised ceramic powder has a high value of hardness, is compatible with the chosen organic carrier and has a very low toxicity. Examples of particularly suitable ceramics have been found from various combinations of aluminium, titanium and silicon with boron, carbon, nitrogen and oxygen. Resulting examples are Alumina, Silicon Carbide, Silicon Nitride, Aluminium Nitride, Titanium Carbide, Titanium Diboride and Boron Carbide. Boron Carbide has been found to be particularly useful for the present invention as it is non toxic, light weight and the th-i3d hardest material known to man.
Advantageously the ceramic powder particles can vary in size within the ceramic loaded composite often having two or more discrete sizes such as a coarse and a fine powder. This.'_allows for closer packing of particles with the carrier. The particle size' distribution can be varied in order to opti-nise the puncture resistance of the resulting material.
Preferred particle sizes are any size below 500=. Above 500-pm it has been.found that although the puncture resistance is still present the coating tends to crack easier due to the large particle size thus reducing the puncture resistance.
Suitable organic carriers have found to be any thermoplastic organic polymer such as polyethylene, polypropylene, polyvinyl chloride, acrylonitrile, polyamide or cellulose-based, or a water soluble polymer based on acrylic acid, acrylamide and/or methacrylic acid. In addition to these natural or synthetic rubbers can be used such as polyurethane, neoprene, and silicone rubbers.
4 Advantageously a plasticiser can be added to the ceramic loaded composite. A plasticiser can enhance the flexibility of the ceramic loaded composite and adds toughness by helping to prevent cracking in the composite. Useful plasticisers have been found to include glycerol, low molecular weight polyethylene glycol, low molecular weight polypropylene glycol, or combinations thereof. A person skilled in the art would realise that these are only examples and can be replaced by other known alternatives.
A further advantage can be achieved by adding a dispersant to the ceramic loaded composite. A dispersant acts to increase the volume of ceramic particles that can be added to the ceramic loaded composite whilst maintaining flexibility in the composite. Increasing the volume of ceramic particles that can be added to the ceramic loaded composite has the.effect of enhancing the puncture resistance of the resulting material. Useful dispersants have been found to include water soluble acrylic ester based copolymers, a sodium dioctyl sulphosuccinate or a stearate. A person skilled in the art would real4se that these are only examples and can be replaced by D--her known alcer-la.Lves'- P-le sit', orirn ippiied c-an be any flexible material lncliding ','Oven m a te r I a I s knitted materials, rubbers, leathers or man made Materials including carbon fibre. The substrate material can a d.ia. n tageously be a puncture resistant material itself such as KevlarS or an alte=arlive aramid fibre. If a puncture resistant--- material -'9 chosen as the substrate material- the comb -ination of --he subsi---ate and the ceramic loaded composite applied to it can together for-n a synergistic effect providing a highly puncture resistant material.
A further advantage can be achieved by only applying -the ceramic loaded composite to specific areas of the substrate material. This gives the advantage of maintaining the high flexibility of the uncoated material whilst providing protection at positions of high risk. When the substrate material is also puncture resistant such as Kevlar(D this embodiment allows for increased protection in some areas whilst maintaining minimal protection in others.
An alternative to applying the ceramic loaded composite to a substrate material is applying the ceramic loaded composite to a substrate fibre either by coating the fibre by any suitable means or impregnating the fibre under pressure to form a composite fibre. The composite fibre can then be formed into a material by known means such as knitting or weaving so as to form a puncture resistant flexible material. This material can then be used to manufacture articles such as clothing for the human or animal body.
The ceramic loaded composite can be produced by a variety of methods depending on the materials used to form the composite. The ceramic powder particles can be formed by ball milling or any suitable industrial process and the ceramic loaded composite can then be produced by stirring or mechanically mixing the ceramic powder particles with the other constituents of the ceramic loaded composite.
The ceramic loaded composite can be applied to the subs'i2'ate-.-.
material again by any suitable process provided it allows the ceramic loaded comnosite to adhere to the substrate material area i-5 coveredthat Suitable met.acds -,iould include coating the subs trat:e -mate.i-Jal b., dipping painting and spraying.
A further advantage can be achieved by applyir.,.g the ceramic loaded composite to a suitas---Le substrate material under pressure so as to impregnate the substrate material with the ceramic loaded composite. Suitable substrate materials would include any material which could hold the ceramic loaded composite such as woven materials, knitted materials, rubbers, leathers or man made materials including carbon fibre and Kevlar(D or an alternative aramid fibre. mpregnating the material with the composite has the advantage of increasing the durability of the material whilst also increasing the puncture resistance of the resulting material.
once the ceramic loaded composite has been applied to the substrate material, eizher bv coating or impregnation or a combination of both, the puncture resistant material is allowed to 6 dry. Drying can be performed under ambient conditions or by heating or by desiccation depending on the ceramic loaded composite and substrate material used.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, wherein Fig 1. Shows a puncture resistant glove having specified areas of the glove coated with a ceramic loaded composite so as to give increased puncture resistance in those areas.
