Importance of Foaming Structural Adhesive Films in Aerospace

Foaming structural adhesive films are crucial in the aerospace industry due to their ability to provide strong, lightweight bonds that can withstand extreme conditions. These materials are used in various applications, including bonding composite structures, reinforcing joints, and enhancing the overall integrity of aerospace components.

The performance of these adhesive films is vital for the safety and efficiency of aerospace vehicles. Therefore, understanding their properties, such as expansion ratio and volatile content, is essential for ensuring they meet the rigorous demands of aerospace applications.

Expansion Ratio

The expansion ratio of a foaming structural adhesive film is a critical parameter that determines how much the material expands when exposed to heat. This property is essential for ensuring that the adhesive can fill gaps and create a strong bond between surfaces. The BS EN 2667-3:2019 standard provides precise methods for measuring this expansion, ensuring consistency and reliability in the performance of adhesive films.

Volatile Content

Volatile content refers to the amount of volatile substances present in the adhesive film. High levels of volatile content can lead to issues such as outgassing, which can compromise the integrity of the bond and the overall performance of the adhesive. The standard outlines methods for accurately determining the volatile content, helping manufacturers produce high-quality adhesive films that meet industry standards.
