Author Information
Author(s): Lin Hong Huang, Yu-Dong Wang, Feng
Primary Institution: Harbin Institute of Technology
Hypothesis
The introduction of hydroxyl groups into the PBO chain will improve the compressive strength of the fiber.
Conclusion
The PBOH fiber has a thermal degradation temperature above 750K and a tensile strength of 3.1 GPa, which is lower than that of PBO fiber.
Supporting Evidence
- The thermal degradation of PBOH occurs above 750 K.
- The tensile strength of PBOH fiber is 3.1 GPa.
- The compressive strength of PBOH fiber is slightly higher than that of PBO fiber.
Takeaway
Scientists made a new type of fiber called PBOH that is supposed to be stronger when squished, but it didn't turn out as strong as they hoped.
Methodology
The PBOH fiber was synthesized using polycondensation and characterized through various analyses including thermal and mechanical testing.
Limitations
The compressive strength of PBOH fiber is still much lower than that of other high-performance fibers like Kevlar.
