Flexural performance of shape memory alloy/CF-PEKK fiber metal laminates for aircraft morphing under varied temperature conditions.

ABSTRACT: In this study, novel Fiber Metal Laminates (FMLs) were manufactured using Nickel Titanium (NiTi) sheets together with Carbon Fiber-Polyetherketoneketone (CF-PEKK) prepregs for different aerospace applications. We have investigated the effect of various temperatures on the flexural properties of NiTi/CF-PEKK FMLs. Prior to manufacture, NiTi sheets were anodized to improve the adhesion between the metal surface with the prepreg. The laminate was then compression molded in a hot-press. The flexural response of manufactured FMLs was investigated at various temperature conditions encompassing martensite and austenite phase of NiTi and glass transition temperature (T_g) of PEKK i.e. (50, 75, 100, and 175 °C). The fractographic studies were completed using optical microscopy and Scannin
