Aerospace adhesives and sealants enable lightweight structural assembly, composite joining, interior installation, environmental sealing and maintenance across aircraft and related aviation platforms. Materials must maintain adhesion under vibration, thermal cycling, pressure changes, moisture and chemical exposure while meeting stringent weight, fire-safety and qualification requirements. Research coverage examines aerospace structural adhesives, sealants, interior bonding technologies and aviation-specific systems, including material performance, application processes, qualification requirements, maintenance needs and supplier strategies.
