B/AP/PVDF复合含能微球的悬浮燃烧特性
Suspension Combustion Characteristics of B/AP/PVDF Composite Energetic Microspheres
摘要
Abstract
Boron(B)-based composite energetic materials,renowned for their high energy density,are employed in explosives and propellant formulations.In this study,B/ammonium perchlorate(AP)/polyvinylidene fluoride(PVDF)composite energetic microspheres were synthesized using an emulsion-solvent evaporation method,with different PVDF mass fractions(5%,10%,15%,and 20%).The surface morphology of the prepared microspheres was characterized via scanning electron microscopy(SEM).To evaluate their combustion behavior,a suspension combustion test was performed using an ultrasonic levitation laser ignition system.Through real-time diagnostics of micro-explosive combustion phenomena,the optimal PVDF content for the en-hanced combustion performance was determined.The results revealed that the prepared microspheres possessed a near-spherical morphology and exhibited a three-stage combustion process(developing combustion stage,stable combustion stage and de-creasing combustion stage),which was also accompanied by micro-explosions.Among the formulations,the microspheres with 10%PVDF demonstrated the most favorable combustion characteristics,exhibiting the largest flame area and brightness,the highest BO₂ emission intensity(11291.8 counts),the greatest BO₂ peak area integration(12856.8),and the highest surface combustion temperature(1243.8℃).These results indicate that the B/AP/PVDF microspheres exhibit optimal combustion char-acteristics and energy release performance at a PVDF content of 10%.关键词
