Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...

Reuse in Architecture & Structural Design

Jan Friedrich Georg Brütting

Introduction The construction industry has an extensive impact on the global environment and will be facing three big challenges in the next decades: reducing its resource consumption, decreasing its energy use, and limiting its waste production. This is e ...

Experimental research on Textile Reinforced Concrete for the development of design tools

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Due to the limited construction experiences as well as to the absence of clear and consolidated design provisions for design of Textile Reinforced Concrete (TRC), the application of this material in practice is still very limited. In this paper, the result ...

Shape memory alloys in fibre-reinforced polymer composites

Véronique Michaud, Amaël Maximilien Cohades

This article reviews the current state-of-the-art in the applications of shape memory alloy (SMA) wires into high performance fibre reinforced polymer composite materials (FRPs). SMAs have been investigated to date to address four main areas of properties ...

In-plane permeability distribution mapping of isotropic mats using flow front detection

Véronique Michaud, Damiano Salvatori, Baris Çaglar

In-plane permeability of textile fabrics is often characterized by one-dimensional rectilinear flow experiments, displaying limitations related to potential race-tracking effects and the need to run experiments at several fiber volume fractions. We propose ...

Ultra low cycle fatigue of welded steel joints under multiaxial loading

Albano António De Abreu E Presa De Castro E Sousa

Extreme loading scenarios such as earthquakes, exceptional wind gusts or tides are characterized by very high amplitude and multidirectional cyclic loads applied to a structure. Ultra Low Cycle Fatigue (ULCF) arises in such cases and can be summarily defin ...

Flexible fabric-based wearable solid-state supercapacitor

Jürgen Brugger, Xiao Sheng Zhang, Bo Meng

In this paper, we present a novel wearable flexible supercapacitor with the conductive carbon-nanotube (CNT)/fabric electrode and PVA/H3PO4 solid-state electrolyte, which is cost-effective and can be easily mass produced. Two kinds of fabric as the electro ...

IEEE Xplore2017

Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...

Temperature effects on material properties and structural response of polymer matrix composites

Wei Sun

Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...

EPFL2015

A number of construction engineering applications for textiles made of composite materials are presented in this chapter. All these structures were fabricated by connecting several subcomponents, usually by using adhesives. Although composite materials are ...
