Abstract: The use of composite surfacing films on aircraft allows for a faster and more cost efficient manufacturing process that also provides a smooth, defect-free surface for painting, chemical resistance and lightning strike protection. Conventional epoxy-based surfacing film products, which find utility in a number of aerospace applications, are limited to a maximum operating temperature of 177°C. Therefore, a need exists for a surfacing film technology for applications requiring higher temperature resistance and protection. As a result, SM X2000 was developed for high temperature applications (>177°C) as a new bismaleimide (BMI) surfacing film that is compatible with a variety of BMI prepregs. The work presented in this paper will discuss the viability of SM X2000 as a surfacing film as well as its excellent lightning strike protection (LSP) performance in multiple lightning strike zone evaluations.
