FRONTAL POLYMERIZATION IN MICROGRAVITY: BUBBLE …
WebSep 29, 2024 · The present study builds on this initial work and has two key objectives: (i) to broaden the analysis of the steady-state propagation of the polymerization front to a wider range of resin systems, and, (ii) as BP occurs simultaneously during FP [21], to investigate the competition between FP and BP in terms of the associated time scales involved … WebAddition of fillers to formulations can generate composites with improved mechanical properties and lower the overall cost through a reduction of chemicals needed. In this study, fillers were added to resin systems consisting of epoxies and vinyl ethers that frontally polymerized through a radical-induced cationic frontal polymerization (RICFP) … WebJ.A.
