Abstract
ABSTRACTIn this work, alkyd resin and 3-glycidyloxypropyl-polyhedral oligomeric silsesquioxanes were synthesized from castor oil and siloxane, respectively, and used to as the modifier of the epoxy resins. Laminate of fiberglass-reinforced composite were prepared from alkyd-epoxy resin with different 3-glycidyloxypropyl-polyhedral oligomeric silsesquioxanes content. The properties of nanocomposite were characterized. The results showed that the 3-glycidyloxypropyl-polyhedral oligomeric silsesquioxanes could increase the impact strength of nanocomposite. When the content of 3-glycidyloxypropyl-polyhedral oligomeric silsesquioxanes is 6 wt% of the alkyd resin, the Tg enhances to 5.2°C, the impact strength increases to 53.01 kJ/m2 (64%), but the tensile strength decreases 15.03 MPa (7.6%). Nanocomposite has good electrical properties and insulating properties.
