Summary: Boiling-induced vibration characteristics and mechanisms were investigated in pool boiling experiments. Turbulence and bubble collapse were identified as the two main mechanisms causing vibration. The peak amplitude of the first natural frequency increased with increasing heat flux and decreasing subcooling degree for turbulence-induced vibration. The peak amplitude of the second natural frequency increased with increasing heat flux for a certain subcooled temperature above 10 degrees C, and remained stable for lower subcooled temperatures. The dominant mechanism transitioned from bubble collapse to turbulence with decreasing subcooled temperature for a certain heat flux. The highest root-mean-square (RMS) value of vibration velocity corresponded to an increasing subcooled temperature with increasing heat flux.

Summary: In this paper, a modified epoxy-based bismaleimide (BMI) resin structural adhesive was developed for bonding BMI-based CFRP with excellent properties. The adhesive was prepared using epoxy-modified BMI as the matrix and PEK-C and core-shell polymers as synergistic tougheners. The modified BMI adhesive exhibited improved processability and bonding properties but slightly reduced thermal stability due to the addition of epoxy resins. However, the inclusion of PEK-C and core-shell polymers synergistically improved toughness and bonding performances, while maintaining heat resistance. The optimized BMI adhesive demonstrated excellent heat resistance, with high glass transition temperature and thermal degradation temperature, as well as satisfactory intrinsic bonding and thermal stability.
