3M delivers complete integrated solutions for fabricating, bonding and protecting composite structures to meet exacting aircraft design requirements.
So much of your aircraft design depends on light weight and durability. That’s why 3M delivers solutions throughout the manufacture, bonding and protection of composite parts. Integrated composite fabrication, bonding and protection options include matrix resins, co-cure structural adhesive films, composite laminate edge sealers, and lightweight structural surfacing films with or without conductive mesh for lightning strike protection. This is all in addition to bonding solutions including paste adhesives, core splice adhesives and more, all formulated for excellent shop handling and efficient application. To learn more about 3M films, resins, sealers and more for fabricating composite aircraft parts, explore our solutions below.
Toughen and bond composite parts with a versatile choice of 3M structural adhesive films, available in a range of weights, carriers and cure temperatures.
Low-density adhesives feature expansion rates up to 250% and variable cure temperatures for streamlined honeycomb structure joining and gap filling.
3M™ Nextel™ Ceramic Fibers reinforce Ceramic Matrix Composites that can be used to fabricate lightweight, high temperature exhaust components and heat shields that help you enable operational efficiency through hotter engine temperatures and lower weight materials relative to existing metallic parts.
Epoxy-based structural adhesive films cure into tough, smooth composite surfaces as well as provide lightning strike protection when a conductive mesh is embedded. Not sure what you're looking for? Use the chart below to help you identify the best product for your needs.

Urethane-based films that can be co-cured with or bonded to composite surfaces to protect against erosion and abrasion damage.
Fast-curing, non-sagging 3M low-density edge and void-filling compounds include the lightest extrudable FR void filler in the aerospace industry.
Appropriate mixing of epoxy and hardener is critical to both the processing and performance of your finished composite part. 3M's Resin Calculator makes calculating the appropriate mix ratio simple. You will need the Certificates of Analyses that shipped with the resin and the hardener where you will find the Epoxy Equivalent Weight (EEW) for each component. Enter the two numbers in the appropriate boxes (Box 1 and Box 4 for the 3M Matrix Resin and Hardener respectively). In Box 2, enter your desired units of 3M Matrix Resin. The calculator will function whether you prefer to mix by volume or by weight. The Charge Ratio in Box 3 can be recommended by 3M Technical Support Personnel by calling 1-800-235-2376. The basic starting point for a Charge Ratio is 1.00. Resin performance can occasionally be improved with a slight under charge (0.95) or a slight over charge (1.05).
