This study improved a homemade apparatus for characterizing the interfacial shear strength of carbon-fiber-reinforced polyphenylene sulfide composites. The upgraded experimental device was easier to operate and showed excellent repeatability and applicability during tests. The addition of a high-frequency data-capturing tool allowed for more accurate identification of the debonding peak force and provided a higher interfacial shear strength value during testing.
This study improved homemade apparatus for characterizing the interfacial shear strength (IFSS) of carbon-fiber-reinforced polyphenylene sulfide (PPS/CF) composites. The upgraded generation II experimental device includes a newly developed experimental clamp for samples, as well as testing systems. Compared with the initial generation I apparatus and the commercial Toei instrument, the generation II device is easier and more efficient to operate. The average interfacial adhesion values obtained using these devices were consistently approximately 40 MPa, with relatively low data scatter, showing excellent repeatability and applicability during microbond tests. Notably, the generation II experimental device was equipped with an additional high-frequency data-capturing tool to identify the debonding peak force more precisely, which demonstrated a higher interfacial shear strength of 42.81 MPa during testing. Therefore, the new instrument was able to reflect the change in the interfacial stress state during the interface debonding process more accurately and reliably.
