Rubber gaskets for aircraft are more effective when high quality standards are maintained during manufacture. Regulators have set high quality standards regarding the materials to be used, the manufacturing process and properties that the final product must have. Specifications for each gasket depend on the model of aircraft and the part where it is going to be used.
Desirable property for a gasket is the ability to work effectively despite high temperature or pressure. Each application surface requires different specifications on thickness. They are used to contain air or liquid by preventing leakage. These products are made of flexible material that covers for less-than-perfect surfaces. This ensures that irregular surfaces do not compromise on effectiveness of the surfaces by causing leakages.
Asbestos have been used as reinforcement for the material considering that they can take high pressure and heat as well. The resulting reaction on the surface is harmful at times which calls for a different consideration. A different material is selected to serve the same purpose without exposing the users or the surface to damage. A material that is yielding to some degree is desirable because it deforms and tightly fills in the spaces between.
The formation of a perfect joint by two mating surfaces ensures effectiveness. This is enhanced by the gasket as it covers the irregularities on the surface. The addition of a sealant helps to ensure that the surface is more effective. The material should be elastic enough to take in the pressure and not be damaged in the process. The ability to maintain the pressure is important for different circumstances.
The best gasket is one which can withstand compression pressure that is applied on the surface during operation. The effectiveness is determined through tests that involve high temperature and heavy compression. The design will be determined by industrial usage, physical parameters, budget and chemical contact. Quick mass production is done using the sheet design but this process is being abandoned because it produces crude pieces.
Graphite is gradually replacing asbestos as the composite material for these pieces. It is fibrous and can withstand high temperatures without compromising effectiveness of changing its chemical properties. It results in pieces that are economical which makes them affordable for all industries. Use of solid materials requires heavy compressing to seal the surfaces and avoid leakage. They are advantageous since they add to the quality of the surface.
The challenges facing gasket manufacturing materials include vulnerability to oxidation. A material that is not easily contaminated is desirable as well as a soft and flexible product that can handle pressure. A spiral wound gasket is produced by adding filler material to make it fibrous. Grips tighten the surface but cannot be used in all instances. Manufacturing procedures need to factor such short comings.
Some of the risks to be watch out for during manufacture of rubber gaskets for aircraft are the evenness of pressure and possibility of losing torque and stress at the joint. An uneven surface is likely to cause leakage especially if it is not smooth. Temperature affects metals and other substances in different ways. This should be considered as well.
