The project "NG_TPfib - New Generation of Fibers for the Reinforcement of Cement Matrix Materials", promoted by Exporplás - Indústria de Exportação de Plásticos, SA and by CiviTest - Research of New Materials for Civil Engineering, Lda., POCI 01 0247 FEDER 033719, funded by the European Regional Development Fund (ERDF) through the Operational Competitiveness and Internationalization Program (POCI), aims to develop a new generation of thermoplastic fibers (TP) for the reinforcement of cementitious matrix materials in the civil construction market.
It is intended to develop fibers with geometric properties and optimized materials that guarantee technical performance and economic competitiveness superior to that registered with the fibers existing in the market, especially for the large segments of market where fiber reinforced concrete (BRF) is used, namely: pavements supported on soil and stakes, tunnels, slopes, and pre-fabrication.
A Exporplás foi fundada em 1981 e é uma empresa global que combina tecnologia de extrusão com tecnologia de processo de polímeros no desenvolvimento e produção de produtos industriais, para diferentes segmentos, como Agricultura, Horticultura, Pesca, Embalagem, Construção e Relva Artificial.
CiviTest - Search for new materials for Civil Engineering, founded in 2001, is a company whose competences are focused on Services, Development and Research in Civil Construction. To carry out these services, the company has a laboratory and a highly qualified team, mostly with a PhD degree.

No presente trabalho executou-se um programa experimental para avaliar os efeitos da exposição a temperaturas elevadas no comportamento residual do betão reforçado com fibras (BRF). O programa experimental executado foi …
In the present work, a multiscale model for fibre reinforced concrete (FRC) beams failing in bending is presented. At the microstructural level, the fibre is modelled as a one-dimensional continuum …
The addition of metallic fibres in concrete is a widely used technique to increase its resistance to crack opening, energy absorption capacity, and durability. The properties of the resulting composite …
No âmbito do dimensionamento da fundação de uma estrutura com grande desenvolvimento, foi prevista a construção de um elemento com secção transversal tubular de parede delgada em betão com um …
Within the scope of the “NG_TPfib” R&D project, Exporplás and CiviTest have, in the recent past, developed a new typology of polypropylene fibers for the production of urban furniture of …
Polypropylene fibres (PP) have been used mainly in non-structural applications for limiting crack width due to shrinkage effects of cement-based materials. Being insusceptible to corrosion, PP fibres can also be …
