Aircraft Engines – Structural (Nacelle)

Surface preparation and protection is a core 3M strength. That’s why we can create solutions that meet the most challenging specifications for metal and composite aircraft engine nacelle systems. Our surfacing films can protect against lightning strikes and microcracks. Co-cure capabilities and virtually pinhole-free formulations can help increase build rates. The unique combination of stiffness and strength of our matrix resins can enable conversion of metal parts to composites for lightweighting. 3M has the broadest range of solutions for your aircraft engine design.

Resin Calculator

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).
