1 Introduction Short-carbon-fiber-reinforced polyether ether ketone (SCF/PEEK) composites possess some superior properties such as excellent mechanical strength, temperature resistance, and biocompatibility, which makes the extensive applications in the aerospace, automobiles and bioengineering [1, 2].

Synergistic experiment-simulation approach studies interface formation Effects of material, process, and geometry on strength are decoupled A novel healing model incorporating crystallization kinetics is proposed Bond strength is governed by two competing mechanisms: interlocking & healing Macro-scale interlocking can become the dominant effect in complex geometries 1 Introduction Fiber reinforced thermoplastic (FRTP) composites are increasingly utilized in automotive and aerospace sectors,...
