This work is aimed at investigating how molecule structure of polyurethanes (PUs) as sizing agents influence the interface properties of carbon fiber (CF) reinforced polycarbonate (PC) composites. Effects of four PUs as sizing agents for CF on the interlaminar shear strength (ILSS) of CF reinforced PC composites are investigated. It is found that the three PUs except PC-PU as sizing agents on oxidized CF (OCF) made the ILSS of their reinforced PC composites increase up to 62.9 MPa by more than 24.8%. The chemical interaction between PU sizing agents and CF are attributed to high reactivity of isocyanate, but carbonate groups on PC-PU may have a chain unzipping reaction due to active groups on the surface of OCF. The chemical interaction between PU sizing agents and PC are attributed to transesterification. As a result, PUs containing isocyanate or polyester groups are ideal sizing agents for CF reinforced PC composites.

“…found that the addition of a soft elastomer, that is, TPU, improved the performance of composites via a tuning fiber network and interfacial interactions between the fibers and the polymer matrix. In fact, for CF‐reinforced composites, the mechanical properties are strongly dependent on the fiber aspect ratio, orientation, volume fraction and fiber–matrix interfacial adhesion …”

In this study, we prepared short-carbon-fiber (CF)-reinforced poly(lactic acid) (PLA)-thermoplastic polyurethane (TPU) blends by melt blending. The effects of the initial fiber length and content on the morphologies and thermal, rheological, and mechanical properties of the composites were systematically investigated. We found that the mechanical properties of the composites were almost unaffected by the fiber initial length. However, with increasing fiber content, the stiffness and toughness values of the blends were both enhanced because of the formation of a TPU-mediated CF network. With the incorporation of 20 wt % CFs into the PLA-TPU blends, the tensile strength was increased by 70.7%, the flexural modulus was increased by 184%, and the impact strength was increased by 50.4%. Compared with that of the neat PLA, the impact strength of the CF-reinforced composites increased up to 1.92 times. For the performance in three-dimensional printing, excellent mechanical properties and a good-quality appearance were simultaneously obtained when we printed the composites with a thin layer thickness. Our results provide insight into the relationship among the CFs, phase structure, and performance, as we achieved a good stiffness-toughness balance in the PLA-TPU-CF ternary composites.
