VICTREX PEEK Polymer Fasteners Boost Next-Generation Commercial Aircraft Cargo Door Manufacturing

Recently, Click Bond, a leading company in the bonded fastener industry, chose VICTREX PEEK polymer to develop a new type of bonded nut plate fastening part for the manufacture of a new generation of commercial aircraft cargo door for large aircraft manufacturers. The fastening member is composed of a fastening bracket and a nut plate and is used to provide support for the joint portion of the cargo door gasket.

The outstanding strength and rigidity of VICTREX PEEK polymer combined with Click Bond innovative adhesive fastener manufacturing process not only can provide the necessary structural integration, but also reduces the installation workload. Adhesion directly to the hardware and structural parts eliminates the need to drill and install rivets. The use of adhesives is not only quick, but also because it is not necessary to drill holes, when it is necessary to adjust the position of attachments and rework attachments, the considerable time and cost of reinstallation can be saved.

The use of rivet holes does not only reduce the number of parts but also reduce the risk of fatigue and erosion. VICTREX PEEK polymer replaces the glass/epoxy composites that were often used to make fasteners. VICTREX PEEK polymer injection molded parts are ideal for replacing glass/epoxy composite parts, especially for large-scale mass production that requires rapid cycle times and reduces part costs. The polymeric material possesses the properties required for structural attachment in aerospace applications, including superior bond strength, high strength and stiffness, excellent flame resistance and hydraulic oil resistance. ”

In addition, the polymer material can also achieve injection molding of thin-walled structures and excellent wettability with high fiber content.

Mark Egeberg, regional manager, Pacific, Click Bond, said: "Click Bond uses a unique self-fastening process to maintain a precise bond position on the substrate when using a permanent structural adhesive. Our 'precise fix' 'The process allows the adhesive to cure smoothly with a constant pressure and a uniform bond layer thickness. The self-fastening part eliminates the need for special tools such as clamps and drills, thus greatly accelerating the process of mounting the stand equipment."
