Study of High-Strength Concrete Reinforced with Bamboo Fibers

Soto H., Marrero R., Benítez F., Medina C., University of Puerto Rico, PR

Concrete is the most used construction material worldwide and, as a consequence, has a significant environmental impact. Cement fabrication accounts for 5 to 10% of the global carbon emission. This has driven scientists to create [...]

Development of Nanosilica-Thermoset Matrix Resins for Prepreg Composites

Nelson J.M., Hackett S.C., Goetz D.P., Hine A.M., Schultz W.J., 3M, US

A review of the prepreg thermoset matrix resin development activities at 3M and commercial status of these systems will be provided.

Degradation and Nanoparticle Release of Epoxy/Nanosilica Composites Exposed to Solar UV Radiation

Pellegrin B., Nguyen T., Mermet L., Shapiro A., Gu X., Chin J., NIST, US

Nanoparticles are increasingly incorporated in polymers to enhance multifunctional properties. However, polymers are prone to undergo photodegradation under UV exposure, resulting in a liberation of nanoparticles from the polymer nanocomposites during their life cycle. The [...]

Toughening mechanisms of nanoparticle-modified epoxy polymers

Mohammed R.D., Johnsen B.B., Kinloch A.J., Taylor A.C., Sprenger S., The University of Trinidad and Tobago, TT

An epoxy resin, cured with an anhydride, has been modified by the addition of silica nanoparticles. The particles were introduced via a sol-gel technique which gave a very well-dispersed phase of nanosilica particles which were [...]
