Highly Uniform Activation of Carbon Fiber Reinforced
Thermoplastics by Low-Temperature Plasma

Nonequilibrium
plasma treatments of carbon fiber reinforced thermoplastic
(CFRTP) composites can activate the robust, chemically inert material
into a nonequilibrium state that can be used to fabricate bonded structural
assemblies with high toughness. The nonequilibrium surface is unstable;
thus, the development of nondestructive characterization techniques
is of paramount importance to assess the material before use. Herein,
a discovery is reported that plasma-activated CFRTP surfaces are characterized
by a sharp, well-defined surface potential distribution, the width
of which is correlated to the fracture toughness of bonded assemblies.
The activated surface has a maximum lifetime on the order of days
to weeks and is hypothesized to be composed of metastable radical-ion
complexes. The hypothesis is consistent with several independent pieces
of evidence, including Kelvin probe force microscopy, contact angle
measurements, magnetic force microscopy, and radical probe experiments.
