Royal Plastic manufactures ultra lightweight composite ducting for a variety of aerospace applications. These ultra light weight ducting systems are used to distribute conditioned air and other fluid media to aircraft components including avionics, cabin and crew. These ducting systems provide an extremely robust and lightweight structure for numerous aircraft platforms. Composite ducting components are designed
to operate in extreme conditions, resist environmental and weathering damage and provide an extremely lightweight solution for demanding applications.
The above shown are ECS ducting
fabricated from carbon fiber with an epoxy resin system,
utilizing a ultra low weight design for
optimum performance. The carbon fiber ducting shown above center,
incorporates a specialized design for military helicopter airframe
platforms. This new ducting utilizes proprietary technology to create
graphite fiber composite ducts capable of zero leakage performance and with
a wall thickness of only 0.013". Stringent requirements on internal air
flow temperature dictate the addition of low density, low thermal
conductivity insulation blankets on many of the ducts. This ultra low
weight design package featured over 70 total parts with a combined
weight of less than 17 lbs. These ducts consistently outperform a
lengthy list of standard military specifications.
Additional features for ultra lightweight ducting systems:
High strength to weight ratio - Composites weigh 32% less than
aluminum and the fibers can be orientated to maximize performance.
Composite structures also provide improved strength and stiffness to
weight performance versus conventional fabricated aluminum structures.
Durability - Composites provide high abrasion and impact resistance
while offering improved fatigue life.
Special Operations - High performance composites can operate under
extreme conditions, temperatures and pressures.
Available fiber reinforcements:
Fiberglass fiber
E-Glass - High strength,
lowest cost fiber, available in many forms, widely used in commercial
and industrial products
S-Glass - Improved strength, higher modulus,
higher cost fiber, used in aerospace and high performance pressure
vessel applications.
Carbon / Graphite Fiber - Increased performance, wide strength range, highest fiber cost,
intermediate density, poor impact or damage tolerance, best tensile
strength and stiffness properties.
Thermoplastics - Including Spectra Shield
® with ballistic
properties
Aramid fiber - Good strength, higher modulus, higher cost fiber, very low density, excellent impact
and damage tolerance properties, poor compression and shear strength.
Kevlar®
Available resins:
Polyester
General purpose polyester - Orthophthalic
polyesters, lowest cost systems,
moderate strength and corrosion resistance, room temperature cure.
Improved polyester - Isophthalic polyesters,
slightly higher cost, good strength and corrosion resistance, room temperature cure.
Vinyl Ester - Chemical combination of epoxy and
polyester technology, excellent corrosion resistance, higher cost,
excellent strength and toughness properties.
Bisphenol-A, Fumarate, Chlorendic - More exotic
systems for improved corrosion resistance in harsh environments, higher
cost resins, higher temperature capability.
Epoxy - Wide range of resins available, best strength
properties, usually heat-cure required, good chemical resistance, higher
viscosity systems, higher material cost, applications across broad
market segment range.
