Thermal, Mechanical, and Microstructural Study of PBO Fiber …
2019年2月18日 · Poly (p-phenylene benzobisoxazole) (PBO) fiber shows fascinating properties including excellent mechanical performance, high crystallinity, and fairly good heat resistance as a kind of polymer fiber. Its properties make it a possible candidate as a precursor of carbon fiber.
The effect of interfacial properties of PBO fiber surface modified …
2024年6月20日 · In present work, the surface of PBO fiber was modified by oxygen plasma treatment with different power and time, and the epoxy resin composite before and after PBO fiber modification was prepared. The results show that the O/C ratio increases with the introduction of carboxyl group on the surface of PBO fiber.

PBO is the strongest and stiffest of commercially available fibers used to repair and strengthen concrete and masonry structures in externally bonded composite systems. [17] In this system, the fibers are produced in the form of a fabric mesh, and a cementitious mortar matrix bonds this to an existing structure.
Poly-p-phenylenebenzobisoxazole (PBO) (Figure 1) forms the strongest synthetic polymer fiber known so far. It provides excellent mechanical properties paired with extreme thermal stability,...

Hybrid Polymer Membrane Functionalized PBO Fibers/Cyanate
2022年1月10日 · Hybrid polymer membrane (TA-APTES), synthesized by tannic acid (TA) and aminopropyl trethoxysilane (APTES) based on the Schiff’s base and Michael addition reaction, is deposited on the surface of poly (p -phenylene-2, 6-benzobisoxazole) (PBO) fibers, and then grafted with epoxy-terminated polysesquisiloxane (POSS) to obtain POSS- g -PBO@TA-APTES...
Enhancing interfacial adhesion and mechanical performance of PBO fibers …
2021年11月8日 · In this study, we proposed an interface regulation strategy with high-precision, that is, the layer-by-layer construction of rigid PDA and flexible PEI, to improve the interfacial properties of PBO fiber composite. We investigated the influence of the (PDA/PEI)n layer on micromorphology and physical–chemical characteristics of fiber systematically.
