Definitions
- This invention is related to fuel pipes or lines, and in particular to fuel pipes for use in aircraft and in particular in the wings of aircraft.
- Conductive polymeric composites can be made by incorporation of specific conductive additives_such as conductive carbon black, carbon fibre, metallic powder, metallic fibre, and intrinsically conductive polymeric powder, e.g. poly-pyrrole or polyaniline.
- the electrical conductivity of an insulating polymer filled with conducting particles or short fibres increases discontinuously at some specific filler content equivalent to the percolation limit. Evenly distributed small spherical particles display percolation at ⁇ 19v/o whereas higher aspect ratio fibres percolate at ⁇ 5v/o.
- a known example ; of an aircraft fuel pipe is disclosed in EP297 990-A in which the pipe body is formed from a insulating composite material such as glass filled epoxy resin and the inner wall of the pipe is provided with a conductive liner.
- the pipes are connected through flanged end fittings which are connected to the conductive liner and are grounded to the aircraft wings.
- the fuel lines are also required to be of low weight with high vibration resistance and good static and fatigue strength in their operational environment.
- low material densities, reduced length and high longitudinal modulus are all advantageous characteristics.
- a material combination with high specific axial modulus (high longitudinal modulus and low density) is required to produce a pipe system with high vibration frequencies.
- composite tubes reinforced with high modulus fibres and in particular high modulus carbon fibre reinforced plastics (CFRP) would be the materials of choice.
- CFRP carbon fibre reinforced plastics
- This invention relates to a means of producing lightweight composites fuel pipes with controlled levels of electrical resistivity intermediate between insulating glass reinforced composites and conductive carbon reinforced composites.
- a glass reinforced composite pipe particularly for use in fuel lines of aircraft, and comprising a body having at least its outer portion comprising an electrically non-conductive polymeric resin matrix having an electrically non-conductive fibre tow reinforcement and a dispersion of electrically conductive particulate filler and having a resistivity of between 50 k ⁇ per metre length and 4.0 M ⁇ per meter length.
- the intermediate levels of resistance are particularly important for pressurised aircraft fuel systems where the aircraft wings are constructed of composite materials.
- the electrieai resistance of the pipe system has to be controlled to semiconductor levels between the low resistance of metals and carbon fibre reinforced plastics and the very high resistance of insulators such as glass-reinforced plastics.
- the resistance is measured along the length of the tube at the outer surface and through the thickness at the opposite ends of a pipe section.
- the resistivity lies between 150k' ⁇ and 1.4M ⁇ and more preferably ⁇ 1.25 MQ.
- the fibre tow may include fibre reinforcements such as E glass, S glass, alumina silicate or polymer fibre which can be impregnated with the matrix resin between individual filaments such that it can be formed into tubes using standard composite fabrication techniques such as filament winding, tape winding, fabric wrapping or resin impregnation techniques .
- fibre reinforcements such as E glass, S glass, alumina silicate or polymer fibre which can be impregnated with the matrix resin between individual filaments such that it can be formed into tubes using standard composite fabrication techniques such as filament winding, tape winding, fabric wrapping or resin impregnation techniques .
- the particulate filler may include cost, high conductivity carbon blacks, and conductive metal oxides such as antimony tin oxide (ATO) or indium tin oxide (ITO).
- ATO antimony tin oxide
- ITO indium tin oxide
- the conductive particulate filler and be incorporated into a liquid thermosetting resin, for example an epoxy resin, using a simple mixing process. In the case of carbon blacks the mixing process should retain the structure of the carbon black and evenly impregnate between individual filaments in the fibre tow.
- the body may further comprise an inner core comprising a non-conductive polymeric resin matrix and an electrically conductive fibre tow reinforcement.
- Fig. 1 is a schematic part cross-section through a fuel pipe/line in accordance with the present invention
- Fig. 2 is graph of resistance data for a tube section according to the present invention
- Fig.3 is a graph of resistance vs weight % of carbon black additive.
- Figurel shows a structurally efficient design based on a composite pipe (P) made from glass fibre reinforced epoxy having semi-conductive properties, electrically connected to a metallic ferrule (F) via a semi-conductive resistive link (L) at the interface between (P) and (F). This is the subject of our invention.
- a hybrid composite pipe can be constructed having a body (B ) comprising two layers, (O) and (C).
- An electrically conductive structural core (C) is made from carbon fibre reinforced epoxy and a more insulative outer layer (O) is made from glass reinforced epoxy having semi- conductive properties.
- the two aluminium alloy end flanges (F) are attached onto outer composite layer (O) though a conductive or semiconductive adhesive similar to the matrix resin in layer (O). Alternatively a more conductive adhesive could be used. This also acts as a seal.
- Outer composite Layer (O) is based on glass fibre reinforced epoxy modified to exhibit a semi-conductive property; in this particular case, an epoxy resin matrix comprising S glass reinforcement and carbon black nano-particulate additions.
- the resistance between the end flanges is governed by the resistive characteristics of layer (O) which is a semiconductor.
- the resistance between the left outer flange and right inner core is governed by the resistive characteristics across the thickness of the composite tube.
- the inner bore resistance is governed by the resistive characteristics of the inner composite layer (C).
- the outer layer (O) utilises a fibre reinforcement of S2 or E glass with fibre volume fraction of -60%.
- Tenax HTS 12k fibre can be used in the pipe core.
- the matrix resin is an epoxy based system - modified with the particulate filler to give the required electrical resistance in the cured composite pipe sections.
- Fibre tows can be accurately positioned in the pipe wall using filament winding techniques in layers dispersed at typically ( ⁇ 89° / +287+28°) in typical thickness ratio (2:5:5). These angles and ratios can be adjusted to match the required mechanical and thermal expansion characteristics of the pipes.
- the inner +89° / +28° layers will be reinforced with Tenax HTS or similar carbon fibre.
- the impregnation matrix system is based on LY556 / HY917 epoxy (Huntsman) having a Enaco 250 Carbon Black filler with BYK-P 9055 (BYK Chemie) dispersing additive.
- the matrix components were mixed at 4O 0 C by stirring at 500rpm.
- the 10% carbon black system consisted of 100 parts by weight (epoxy) resin, 10 pbw (carbon black), 2 pbw dispersant.
- the lower carbon black matrix systems may be produced by the addition of further quantities of the mixed epoxy resin followed by further stirring.
- the S2 glass fibre tows were impregnated with the resin system using standard filament winding procedures.
- the end fittings will be bonded and sealed in place with either EA 9394 or EA 9395 or if controlled electrical resistance of the bond interface is necessary, with an epoxy based on the composite matrix resin.
- the liquid rheological dispersing additive was used to break up agglomerates, stabilize the carbon black and prevent sedimentation, separation or floating. In this way electrical percolation is maintained throughout the matrix at a level of 8-10 % by weight of carbon black addition whilst at the same time maintaining the viscosity of the resin at ⁇ 1000 cp at 40-50°C as required for filament winding and liquid impregnation. At the same time the good mechanical integrity of the composite is maintained.
- the resulting fibre reinforced composite pipes exhibit other advantages over metallic pipes, i.e., they are lighter in weight, more resistant to corrosion, more inert and the expansion coefficients can be tailored.
- Pipes in accordance with the present invention containing 10% by weight carbon black and having an ID of 20mm and OD 21.4 mm with a fibre angle of 45° were tested for resistance as measured between the end fitting and the opposite end pipe bore and between the two end fittings along the pipe outer surface.
- the electrical resistance across a typical carbon fibre reinforced filament wound tube from the bore at one end to the outer machined surface of the other end is ⁇ 25 ⁇ m "1 in contrast to a similar glass reinforced composite tube which would be highly insulating at >200M ⁇ m "J .
- These values may be affected by the surface absorption of the aviation fuel but since the electrical conductivity is low at typically 50-450 pSm "1 the effect is expected to be minimal.
- the pipe according to the present invention has a resistance measured using digital volt metre of ⁇ 137 ⁇ m ' ' for a 1000mm length of pipe. This value does not vary significantly over the operational temperature range.
- the resistivity of pipes may be controlled by varying the amount of the carbon black contents as is shown in Fig. 3. Resistance of between 1.4 M ⁇ and 22 M ⁇ were achieved between 8-10w/o of carbon black. Lightning impulse voltages of 900V transient have been applied to a hybrid composite pipe section according to the present invention without any signs of sparking between layers within the pipe, or at end fittings.
- the thermal expansion coefficients can be controlled by the details of the fibres and angles used in the windings.
- the thermal expansion coefficient along the pipe axis can be controlled with the fibre angles and thicknesses used in the winding.
- the estimated longitudinal expansion coefficient is ⁇ 10 ppm 0 C "1 for S2 glass reinforcement and ⁇ 4 ppm 0 C "1 for a typical S2/carbon hybrid structure.
