Abstract
An impact resistant conduit is formed from braided carbon fibre 12 and resin. The braid is made up of a number of strands 10. The use of carbon fibre allows for a conduit of smaller mass. The conduit may have a water or liquid proof coating or an electrical or EMC coating or an abrasion reducing coating on the inner or outer surface. The conduit may be made in a mould which may be inflatable.

IMPACT RESISTANT CONDUIT
The present invention relates to an impact resistant conduit, electrical wiring housed in the conduit, and transport using such a conduit.
Exposed electrical wiring, for example forming part of a wiring harness, is presently protected from damage by being housed or sheathed in metal tubing. A typical metal is stainless steel.
However, metal is relatively heavy and, in the case of stainless steel, extremely expensive.
The present invention seeks to overcome this problem.
In accordance with a first aspect of the present invention, there is provided an impact resistant conduit comprising impact resistant material which includes a composite mixture of resin and carbon fibre.
Preferable and/or optional features are set forth in claims 2 to 20, inclusive.
In accordance with a second aspect of the invention, there is provided a method of forming an impact resistant conduit, in accordance with the first aspect of the invention, comprising the steps of: (a) braiding a plurality of elongate flexible elements formed from the impact resistant material onto a former; (b) heating the braided impact resistant material so that the plurality of elongate elements form a unitary impact resistant conduit; and (c) forming the unitary impact resistant conduit into a desired shape.
The invention will now be more particularly described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 shows part of apparatus used in a method of forming an impact resistant tube, in accordance with the second aspect of the invention; and Figure 2 shows ajig used in the method of forming an impact resistant tube.
One embodiment of an impact resistant tube will now be described, by way of example only, with reference to the drawings. The impact resistant tube, having an uninterrupted circumference, is formed from impact resistant thermoplastic material being a composite mixture of carbon fibre, poly-paraphenylene terephthalamide-based (for example Keviar ) fibre, and resin.
This material is impregnated and available from Schappe Ltd. at B.P. 8901800 Charnoz, France under the trade name TPFL .
The resin is one or more of polyetheretherkeyton (PEEK), polyphenylenesulphide (PPS), polyetherimide (PEL), polyamide (PA) polypropylene (PP), and the fibres are provided in an amount of 40% to 70% fibre volume fraction. No halogens are present.
The impact resistant material is initially formed as an elongate flexible element, for example a yarn, tape or thread. Referring to Figure 1, a plurality of the elongate elements 10 is braided unidirectionally. The braiding is initiated, and then a rigid elongate former (not shown) is coaxially inserted, and braiding is completed on the former.
The flexible braided material 12 and former are placed in an oven and heat treated, so that the elongate elements form a homogenous matrix or unitary tube on the former.
The unitary tube is cooled, and the former is removed. The unitary tube is then post-heated to slightly soften the impact resistant material to allow post-forming.
As shown in Figure 2, a jig 14 is utilised to post-from the unitary tube. Once softened, the unitary tube is placed in a channel 16 of the jig corresponding to a desired shape of impact resistant tube The unitary tube is held in the jig 14 until the material has cooled. Once cooled, the impact resistant tube assumes a rigid hollow structure which retains its shape.
In a second embodiment of a method for forming the impact resistant tube, unidirectional braiding of a plurality of the elongate elements is again initiated. A former is again coaxially inserted However, the former is an inflatable and deflatable bladder-type former. Unidirectional braiding is completed on the deflated former.
The flexible braided material and deflated former are placed in a mould which defines the finished shape of the impact resistant tube. The former is inflated, so that the braided material is pressed against the internal sides of the mould. The mould together with the braided material and inflated former are heated in an oven. The yarns or threads again form a homogenous matrix or unitary tube along the former.
The mould is cooled, and the former is deflated and removed from the unitary tube. The impact resistant conduit is thus formed and shaped simultaneously, or substantially simultaneously, and without the need for a separate jig.
One or both formers, and thus the finished tube, can have a round, oval or substantially quadrilateral cross-section. Other cross-sectional shapes are possible.
The tube typically has diameters which range from 6 mm to 50 mm, and with a wall thickness that ranges from 0.3 mm to 5.0 mm.
Shapes such as two dimensional and three dimensional bends, flairs and belling can be imparted to the tube by the methods described above without reducing structural integrity. Consequently, complex and tortuous paths can be formed without weakening the tube.
Once cured, the tube maintains structural integrity up to 65% crush resistance, is 75% to 80% lighter by volume than stainless steel; and is heat resistant in the range of- 150 C to 350 C, though more preferable operating parameters are -70 C to 260 C The tube exhibits excellent flame, smoke and toxicity resistance as well as being resilient to fuel, oil, solvent and chemical exposure.
An interior coating can be applied to the former before winding the impact resistant material. The coating can be a abrasion reducing coating, such as PTFE; an electrical and/or EMC screening coating; and/or a fluid impermeable coating. More specifically, the fluid impermeable coating can be a liquid impermeable coating.
An exterior coating may alternatively, or additionally, be provided. The coating can also be an abrasion resistant lining, such as PTFE. Alternatively, the coating can be plating, which easily takes to the impact resistant material. The plating can be, for example, gold, nickel, copper, zinc or any other plating suitable for a given application.
The exterior coating can also provide electrical and/or EMC screening.
The tube can be integrated as part of a Connector adaptor, Backshell, harness boot; and/or primary conduit. This is particularly beneficial in protecting an exposed electrical harness on, for example, the undercarriage of an aeroplane which is especially vulnerable to projectile impact during take-off and landing. Furthermore, due to the light weight of the tube, overall weight is reduced in comparison to traditional metal impact resistant tubing.
The impact resistant tube is stiff, reducing the need for brackets and p' clips supporting the wiring or harness.
The tube can also be utilised, for example, in the masts of ships due to its high rigidity and low weight.
In use, electrical wiring may be fully enclosed by the impact resistant tube, or may enter and exit the tube as required.
Although the impact resistant tube has been described as being applicable to aircraft and ships, it can be utilised on any transport, or indeed in any area, where exposed electrical wiring is subject to projectile damage.
Other types of conduit, as alternatives to a tube, can be formed from the impact resistant material. The conduit may have a non-continuous circumference, for example having a U- or C- shaped cross-section.
Although Kevlar fibres are used in conjunction with the carbon fibres, it may be possible to dispense with the Kevlar fibres, or utilise alternative fibres, such as R- Glass.
It is thus possible to provide an impact resistant conduit which is more cost- effective to produce than a traditional stainless steel protective tube or conduit, which exhibits better impact resistance, and which is lighter.
The embodiment described above is given by way of example only, and modifications will be apparent to persons skilled in the art without departing from the scope of the invention as defined by the appended claims.
