Fracture Toughness and Failure Mechanisms of Glass-Reinforced Plastics Based on an Epoxy Matrix Modified with Polysulfone and an Active Diluent

Tuyara V. Petrova, Ilya V. Tretyakov, Olga V. Alexeeva, Andrey Yu. Sergeev et autres

The crack resistance of unidirectional fiberglass-reinforced plastics based on an epoxy matrix modified with polysulfone (PSU) and furfuryl glycidyl ether (FGE) was investigated. The combined addition of PSU/FGE modifiers to the epoxy matrix increases the crack resistance of glass-fiber-reinforced plastics (GFRPs). The …

Fracture Toughness of Winding Carbon Plastics Based on Epoxy Matrices and Reinforced by Polysulfone Film

E. B. Dzhangurazov, Tuyara V. Petrova, Alexey V. Shapagin, Ilya V. Tretyakov et autres

In this work, the fracture mechanism of winding carbon-fiber-reinforced plastics (CFRPs) based on epoxy matrices reinforced by polysulfone film was investigated. Two types of polymer matrices were used: epoxy oligomer (EO) cured by iso-methyltetrahydrophthalic anhydride (iso-MTHPA), and EO-modified polysulfone (PSU) with active …
