Enhancement of the mechanical performance of an epoxy resin and fiber reinforced epoxy resin composites by the introduction of CNF and PZT particles at the microscale

Vapor growth carbon nanofibers (CNF), lead zirconate titanate piezoelectric (PZT) particles, as well as a combination of these two were added in an epoxy resin (EP), and their influence on the mechanical quasi-static properties was investigated. Moreover, the prepared samples were characterised by dynamic thermal mechanical analysis, and optical and scanning electron microscopy. Enhancement of the mechanical properties was observed by the addition of the CNF. The uncured mixtures were also used as matrix material for manufacturing unidirectional carbon fiber reinforced laminates.
