Types of Aerospace Insulation Materials
Aircraft insulation materials are used throughout the interior of most airplanes to reduce noise levels and protect passengers from excessive temperatures. Aerospace Insulation Materials are typically made from an insulator surrounded by an aircraft-rated plastic covering to hold the material in place and prevent moisture from entering the aircraft. Aerospace insulators also include flame retardant properties to minimize the risk of fire and aid in reducing the spread of a fire once it has ignited.
Depending on the aircraft type, aerospace insulation needs can vary greatly. For example, engine nacelles or encasements require thermal insulation to maintain consistent internal operating temperatures and avoid heat loss that can damage the inner workings of the aircraft and outer casing. Flexible microporus insulation is an effective choice to meet these requirements. It can be molded into tight spaces to provide a custom fit while still meeting all required temperature, weight and performance specifications.
Mica insulation is another option to consider for aerospace applications. It’s a lightweight, flame retardant material that can be manufactured into a variety of shapes for various aircraft applications. For example, mica roll laminates can be used to insulate ducting and tubing. It can also be used to manufacture insulation pads, curtains and expansion joints. Mica is ideal for aircraft insulation because of its high temperature resistance and ability to withstand harsh environments.
Thermocouple insulators, light-duty stand-off insulators, heavy-duty stand-off insulators and suspender insulators are other types of insulators that can be used in the Aerospace industry. These insulators are often made from ceramic and composite materials that have an abrasion, chemical, corrosion and moisture resistant coating. They are typically made of alumina, zirconia, mullite, cordierite or steatite and can be provided in cylindrical, conical or flat forms.
Most Aerospace insulation materials must have flame-retardant properties to reduce the risk of in-flight fires and assist in preventing or delaying post-crash fuel fires from igniting in the fuselage. These insulators are also able to withstand the rigors of an aircraft’s harsh environments and safeguard critical electronics.
In addition to insulating against temperatures and sound, aviation insulation is also required to prevent the transmission of unwanted vibrations throughout the aircraft’s structure. This is essential to ensuring passenger comfort, as well as limiting the damage that can be caused by vibrations on aircraft components and structural parts.
Aerospace tapes are designed to make composite molding easier to handle and boost bonding, sealing and insulation performance. They are available in a variety of thicknesses, widths and colors to match the specific requirements of any aircraft. They’re designed to provide an ideal surface for composite bonding, protect against fluids, improve handling and speed up installation times. They’re also abrasion and corrosion resistant and can be supplied with an anti-stick coating to ensure clean removal from the surface of the aircraft.
