Structural Bonding of Aircraft Airframes and Components

3M have been bonding aircraft and helicopter airframes and components for over 50 years. Today, our product portfolio is primarily focussed on epoxy adhesive technology, providing high performance solutions for the manufacture of aircraft structures, enabling structural bonding with elevated efficiency and repeatability

The following products are examples of 3M solutions for structural bonding in the manufacturing of aero-structures, such as airframes and components. Our product portfolio is based on both adhesive bonding products such as adhesive films or pastes and sandwich construction solutions like low density void fillers or core splicing films. These solutions have been designed for both composite and metal structures.

Structural adhesive films

Structural adhesive films

3M have a wide range of adhesive film solutions for the aerospace industry. The main technology is modified epoxy chemistry which, depending on product choice, will provide medium to high temperature resistance with typical cure cycles from 120°C to 180°C.

Today our products are used to structurally bond a wide range of substrates like thermosetting and thermoplastic composites, aluminium and titanium. With regards to composites, our adhesive film portfolio enables co-curing, co-bonding or bonding of cured composites.

Structural paste adhesives

Structural paste adhesives

3M have a wide range of paste adhesives adapted for the aerospace industry. The majority of products are reactive 2 part paste epoxy adhesives curable at ambient temperature. The paste adhesive portfolio serves the aircraft and helicopter industry with both high performance toughened solutions as well as flexible solutions with a wide range of working-life after mixing.

As you would expect, our products enable great bonding strength and adhesion to commonly used aircraft substrates such as composites and metals. Most of our products have been designed for automatic dispensing on and are also available in easy-to-use duo-pack cartridges.

Low density void fillers

Low density void fillers

3M have a complete range of epoxy based low density void fillers specified for the aerospace industry. We serve the market with heat-curing solutions and ambient curing reactive 2 part systems.

Our low density void filler range is usually used in combination with sandwich structure manufacturing where our product will provide local core reinforcement or durable edge close out.

3M’s in-house technology of glass-microspheres in combination with epoxy technology makes us unique in this market segment providing modern solutions adapted for the aerospace industry applications.

Core splice films

Core splice films

3M have a complete range of structural core splice films. These thermo-foaming, epoxy based, heat-curing systems are typically used in combination with sandwich structures. Our core splice film range is used as a splicing solution between two honeycombs, complex gap-filling or for edge close out.

These products will offer you a a selection of expansion ranges and are co-curable in combination with composite materials or metal using standard aerospace cure cycles from 120°C to 180°C.
