| Abstract: | The effects of diaryliodonium salt as photoinitiator and N-vinylcarbazole as photosensitizer and glycerol as chain-transfer agent on UV curing cationic bisphenol A epoxy resins are investigated.A UV-curable cationic bisphenol A epoxy matrix resin formulation is developed.The glasscloth-reinforced composites are fabricated with it by wet-layup technique and by ultraviolet irradiation.The mechanical properties of the composites are evaluated.Based on these measurements,it may be concluded that UV curing route to the fabrication of glass cloth reinforced composites based on bisphenol A epoxy resins provides a feasible route to the fabrication of composites with good mechanical properties. |
