Desarrollo de materiales nanocompuestos poliméricos de bajo coste con prestaciones mecánicas mejoradas

Presentación oral en XXXIII Reunión Bienal de la real Sociedad Española de Física (2011).  C. Manteca, A. Yedra y J. González  Resumen: El empleo de materiales compuestos poliméricos (composites) se ha incrementado rápidamente en todo el mundo, debido a que aportan importantes ventajas frente al uso de materiales tradicionales, como los metales, consiguiéndose mediante su formulación mejores propiedades específicas a la medida de la aplicación. Inicialmente su uso fue en sectores tecnológicamente punteros como la aeronáutica, aunque el avance tecnológico y la disminución de costes de producción han provocado que en la actualidad su demanda venga de otros sectores como...

Polymeric nanocomposite low cost and high performance materials development

Presentación oral en XXXIII Reunión Bienal de la real Sociedad Española de Física (2011).  C. Manteca, A. Yedra y J. González  Abstract  The aim of the project was to develop multiscale thermoset composite materials with better mechanical qualities. These materials mix traditional reinforcements (as glass fiber) with carbon nanostructures reinforcements (multiwall carbon nanotubes, carbon nanofibers, and carbon nanostructures from tire recycling). The main challenge was to transfer carbon nanostructures qualities to the polymeric matrix. This came from a good dispersion of the nanoreinforcement in the matrix, avoiding conglomerates. To prevent this CTC used an advanced dispersion technique, Three Roll Mill.... Read More

Synthesis of graphene from graphite

Presentación oral en XXXIV Reunión Bienal de la Real Sociedad Española de Química (2013). M. González, A. Yedra, P. Mantilla and C. Manteca Abstract: In the present work a comparative survey has been done using highly oriented pyrolytic graphite (HOPG) and from graphite waste powder as starting material. Graphite waste is used for the purpose of reusing an industrial waste product and for a cheaper production cost of graphene. FT-IR spectra showed that the chemical oxidation was performed. XRD spectra proved graphene oxide nano-platelets and reduced graphene oxide formation. Raman spectra confirmed graphene oxide nano-platelets formation. And, AFM measurements show... Read More

Composite material pedestrian bridge for the Port of Bilbao

IOP Conf. Series: Materials Science and Engineering 40 (2012) 012040. I. Gorrochategui, C. Manteca, A. Yedra, R. Miguel and F. J. del Valle Abstract: Composite materials in comparison to traditional ones, steel and concrete, present advantages in civil works construction: lower weight, higher corrosion resistance (especially in the marine environment), and ease of installation. On the other hand, fabrication costs are generally higher. This is the reason why this technology is not widely used. This work illustrates the process followed for the design, fabrication and installation of a composite material pedestrian bridge in the Port of Bilbao (Northern Spain). In... Read More
