Design, pultrusion manufacturing, characterization, and reliability testing of a novel PMMA-based glass FRP composite material

open access: yesTransportation Engineering, 2022
Thermosetting resins have a limited ability to absorb impacting energy and deform in the transversal direction. Thermoplastics, on the other hand, are reformable meaning their shape can be modified after the polymerization process has occurred.

Clay−Fulleropyrrolidine Nanocomposites [PDF]

open access: yesJournal of the American Chemical Society, 2006
In this work, we describe the insertion of a water-soluble bisadduct fulleropyrrolidine derivative into the interlayer space of three layered smectite clays. The composites were characterized by a combination of powder X-ray diffraction, transmission electron microscopy, X-ray photoemission and FTIR spectroscopies, and laser flash photolysis ...
