PBX炸药热分解研究进展OA

The thermal decomposition of polymer-bonded explosives(PBX)under complex service environments represents a quintessential multiscale,multiphysics challenge.While progress has been made at individual scales,current research remains fragmented,lacking a cohesive framework that integrates molecular chemistry,mesoscopic damage evolution,and macroscopic thermo-mechanical response.This review systematically synthesizes the state-of-the-art in PBX thermal decomposition,covering methodologies,applications,and critical influencing factors.The key frontiers for future research were identified,including high-spatiotemporal-resolution in situ characterization,multiscale predictive modeling,and decomposition kinetics under con-finement.Ultimately,developing physics-based life prediction models is pivotal for accurately assessing munition health and guiding the design of robust,aging-resistant formulations.
