Mechanical behaviour assessment of unsaturated polyester polymer mortars filled with nano-sized Al 2 O 3 and ZrO 2 particles

Autor: S P B Sousa, Maria Cristina Ribeiro, P. R. O. Nóvoa, Celeste M.C. Pereira, António Ferreira

Publikováno v: Ciência & Tecnologia dos Materiais. 29:e167-e171

There are several ways to change the final properties of composite materials, but the most common one is by adding different types of modifier fillers to the polymeric matrix. Over the last years, nano fillers have brought some interesting properties

Multifunctional Material Systems: A state-of-the-art review

Autor: António Marques, André Duarte B.L. Ferreira, P. R. O. Nóvoa

Publikováno v: Composite Structures. 151:3-35

An increase in system-level efficiency and multifunctionality of products and components is one of the main advantages of the use of some novel polyvalent materials and structures. This polyvalence or multifunctionality is currently a hot topic in sc

Polymer Composite Materials Modified with Nano-Oxides and Phosphinates Hybrid Flame Retardant Systems

Autor: Celeste M. Pereira, P. R. O. Nóvoa, António Ferreira, S P B Sousa, Maria Cristina Ribeiro

Publikováno v: Key Engineering Materials. 634:527-536

Unsaturated polyester based composites materials present several improved properties over conventional materials. However, these composites show great sensitivity to high temperatures and poor fire behaviour. In the present study, an effort is undert

Fire retardancy enhancement of unsaturated polyester polymer resin filled with nano and micro particulate oxide additives

Autor: S P B Sousa, P. R. O. Nóvoa, Celeste M.C. Pereira, Maria Cristina Ribeiro, António Ferreira

Publikováno v: IOP Conference Series: Materials Science and Engineering. 58:012020

In the last years the traditional construction materials, such as wood, glass and steel, have been increasingly replaced by polymer composite materials due to their superior properties. However, this feature has also raised buildings' combustibility
