Ongoing master’s research on interphase behavior and thermomechanical performance of CFRP/PEI hybrid laminates for aerospace fuel tanks under controlled degradation. Thermal stability evaluated via TGA, viscoelastic properties studied with DMA, and microstructural features analyzed using microscopy to understand degradation effects on interfacial bonding and laminate performance.

Experimental research on high-performance thermoplastic and thermoset composites, focusing on thermal and microstructural characterization. DSC analysis of PEEK (crystalline/amorphous), PEI, PPS, and PES to study thermal behavior and phase transitions. Composite laminates prepared via hand lay-up and vacuum bagging. Metallographic specimen preparation for optical microscopy and microstructural analysis. Data analysis, interpretation, and documentation, including technical reports and presentation of results

Thermal characterization of ER563 epoxy resin, analyzing curing behavior, glass transition temperature (Tg), and thermal stability using Differential Scanning Calorimetry (DSC). Dynamic and isothermal measurements at various heating rates explored curing kinetics, degree of cure, and post-curing behavior, supporting optimization for high-performance composite applications.
