Electrically Conductive Tape & Composite Adhesives

Available in various formats and styles to meet specific requirements, electrically conductive tapes are essential for enhancing functionality and reliability in a wide range of applications. Some of the most popular types include electrically conductive adhesive tape and electrically conductive film, both of which provide reliable electronic isolation and ensure that direct electrical connection is not made between two or more circuits or their adjacent parts.

Electrically conductive tapes and films are used in many fields, including electrical, medical, and pharmaceutical, and can serve various purposes. Thanks to their durability in elevated temperatures, reliable electrical-contact capabilities without the need for pressure, and consistent adhesive capabilities, electronic tapes function well under even under significant environmental and mechanical stress.

Bonding of Composite Materials

Providing strength and reliability in critical applications, composite adhesive bonding helps engineers meet specific performance requirements. The process of bonding an array of similar or varied materials — such as fiber- and particle-reinforced thermosetting composites, carbon-matrix composites, metal alloys, polyester, titanium, glass, and rubber — composite bonding involves a matrix and a reinforcement; when combined, their different physical and chemical properties impart new properties, producing a single system. The most common composites are carbon fiber and glass fiber, as well as Kevlar and graphite-reinforced materials.

Adhesives for composite materials allow for optimal mechanical strength, protection against impacts and fractures, and provide mechanical and cryogenic shock resistance. These bonds also provide electrical insulation, allow for low shrinkage rates, and easily resist thermal cycling.

However, proper safety protocols must be followed to ensure long-term functionality of bonded parts. Environmental conditions, joint configuration, surface preparation, and adhesive properties must all be taken into consideration.

Adhesives Used in Composites Bonding

Because various applications require different types of bonding, there are a multitude of adhesives to choose from depending on the industry. Commonly used in the aerospace industry, composite adhesives are also used in automotive manufacturing, orthopedic devices, sporting equipment, and medical appliances.

Conductive film adhesives, electrically conductive tape, composite bonding tape, industrial nonstick fabrics, and heat sealing tapes are important in many composite bonding processes, as these materials provide insulation and resilience against harsh elements, thereby protecting consumers and manufacturers from fire hazards and shock risks. In production and manufacturing processes, these tapes and films can mask or hold parts in order to protect them from damage, and can also provide electrical conductivity across or between adhesive bonds.

Depending on the specific materials that will be bonded, several factors should be taken into consideration when choosing a structural adhesive for composite bonding purposes. Environmental factors like humidity and UV exposure must be kept in mind, as well as any potential mechanical challenges such as impacts and vibration. It’s also important to consider resistance to various chemicals, such as jet fuel or motor oil.
