“…After radiological assessment, the histological specimens were demineralized by specially prepared solution28 and dehydration was then performed using a graded series of ethyl alcohols and clearing with a xylene substitute. They were embedded in paraffin, and the specimens were cut sagittal direction to make histological sections 4‐μm thick and stained with hematoxylin‐eosin.…”

A series of graft interpenetrating polymer networks (IPNs) were prepared from epoxy (EP) and castor oil-based polyurethane (PU). The dynamic mechanical properties, as well as the tensile and impact strength, of the IPNs were studied systematically. Results revealed that PU/EP IPNs showed improved damping properties compared with that of EP matrix. In addition, the PU content and testing frequencies had much influence on the damping properties of the IPNs. The IPN composites showed better damping properties with higher PU content or under higher testing frequencies.Mechanical analysis showed that the tensile strength of IPN composites was higher than that of pure EP. However, higher PU content (beyond 5 wt %) impaired the impact strength of the IPNs. It is expected that PU/EP IPNs may be potentially used as structural damping materials.
