Oriented fibrous structures for concrete reinforcement

This paper reports on the work that is being undertaken at the University of Minho concerning the development of directionally oriented fibrous structures (DOFS) to be used as a concrete reinforcement material. Several glass fibre wovenlike DOFS were produced varying two parameters: roving linear density (tex) and reinforcement structural density (rovings/cm). Self-compacting concrete slabs were reinforced by D...

Mechanical properties of composite materials made of 3D stitched woven-knitted ...

This article presents an experimental investigation carried out to understand the mechanical behavior of composite materials made of 3D stitched woven-knitted basalt fabrics. The innovative preforms used consist of two outer layers of a plain woven fabric combined with two inner layers of weft-knitted fabrics. The weft-knitted fabrics selected for the study were varied plain knit, 1 × 1 rib, Milano, and interlo...

Development of weft-knitted and braided polypropylene stents for arterial implant

Textile biomedical materials have been used for various applications contributing considerably in improving quality of life. The current study aims at improving polypropylene fibre stents which may replace metallic ones. In order to produce the stents, weft-knitting and braiding technologies were used. In the braiding technique, by varying the takeup ratio (using gears with the appropriate number of teeth in th...

Multifunctional braided composite rods for civil engineering applications

This paper presents the development of a braided reinforced composite rod (BCR) able to both reinforce and monitor the stress state of concrete elements. Carbon fibers have been used as sensing and reinforcing material along with glass fiber. Various composites rods have been produced using an author patented technique based on a modified conventional braiding machine. The materials investigated were prepared w...

3D textiles for composite reinforcements

This paper presents an overview on the last developments on 3D textile structures for composite reinforcements. The application of innovative 3D shaped weft-knitted preforms in GFRP tube joints is presented and discussed. Moreover, the mechanical behaviour of 3D hybrid basalt fiber reinforced composite material sis also presented and discussed.

Self-monitoring composite rods for sustainable construction

This paper presents the development and properties assessment of braided reinforced composite rods (BCR) able to both reinforce and monitor the stress state of concrete infrastructures. The research study aims at understanding the tensile behaviour and self-monitoring ability of composite rods reinforced by a textile structure – braided structure with core reinforcement – for civil engineering applications, nam...

Hybrid composite rods for concrete reinforcement

The current work is concerned with the development of braided composite rods for civil engineering applications, namely for concrete internal reinforcement, as a steel substitute. The research study aims at understanding the tensile behaviour of composite rods reinforced by a textile structure – braided structure with core reinforcement.Seven types of braided composite rods were produced, varying the type of fi...
