Intralaminar fracture of unidirectional carbon/epoxy composite: experimental results and numerical analysis

Fracture of carbon fiber reinforced polymers (CFRPs) is dominated by large scale fiber bridging which acts as a very important toughening mechanism. The objective of this paper is to investigate the intralaminar Mode I fracture in a unidirectional CFRP com ...

Micromechanical design of hierarchical composites using global load sharing theory

William Curtin, Varun Parameswaran Rajan

Hierarchical composites, embodied by natural materials ranging from bone to bamboo, may offer combinations of material properties inaccessible to conventional composites. Using global load sharing (GLS) theory, a well-established micromechanics model for c ...

Temperature Dependent Impedance Spectroscopy and Thermally Stimulated Depolarization Current (TSDC) Analysis of Disperse Red 1-co-Poly(methyl methacrylate) Copolymers

Frank Nüesch, Yee Song Ko

The dielectric relaxation processes of polymethyl methacrylates that have been functionalized with Disperse Red 1 (DR1) in the side chain (DR1-co-MMA) were studied with temperature dependent impedance spectroscopy and thermally stimulated depolarization cu ...

Structural concept and design of a GFRP-polyurethane sandwich roof structure

Thomas Keller, Sonia Yanes Armas

This work presents the concept and structural design of a 1000-m2 glass fiber-reinforced polymer (GFRP) sandwich roof replacing a timber roof over an indoor swimming pool. The advantages offered by the lightweight, multifunctional GFRP-polyurethane (PUR) s ...

Stress Analysis of Unbonded and Bonded Prestressed CFRP-strengthened Steel Plates

Alain Nussbaumer, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

Numerous research studies are available in the literature on strengthening of steel members using carbon fiber reinforced polymer (CFRP) composites. Although it is clear that strengthening using prestressed CFRP plates has several advantages over non-prest ...

Optically-derived mechanical properties of glass fiber-reinforced polymer laminates for multifunctional load-bearing structures

Thomas Keller, Anastasios Vassilopoulos, Andreas Schueler, André Gabriel Kostro, Julia De Castro San Roman Fest, Carlos Pascual Agullo

This paper demonstrates how the translucency of glass fiber-reinforced polymer (GFRP) laminates allows the derivation of their mechanical properties through optical measurements. Spectrophotometric, goniophotometric and tensile experiments were performed o ...

Assessment of solvent capsule-based healing for woven fibre-reinforced epoxies

Erica Manfredi

Structural fibre-reinforced composites based on brittle matrices such as epoxy resins may be subject to short-term subcritical matrix damage that develops with time to the point where it may compromise the integrity of the structure. Currently, components ...

Antibacterial surfaces based on functionally graded photocatalytic Fe3O4@TiO2 core-shell nanoparticle/epoxy composites

César Pulgarin, Yves Leterrier, Sami Rtimi, Tommaso Nardi

Functionally graded epoxy composites with various concentration profiles of Fe3O4@TiO2 core-shell nanoparticles (NPs) were synthetized and characterized, with focus on their antibacterial properties. The NPs consisted of rutile, anatase, magnetite and hema ...

A review of the fire behaviour of pultruded GFRP structural profiles for civil engineering applications

Thomas Keller, Yu Bai

Pultruded glass fibre reinforced polymer (GFRP) profiles are finding increasing applications in civil engineering structures, owing to the several advantages they offer over traditional materials. However, due to the combustible nature of their polymer mat ...

Fatigue and fracture behavior of adhesively-bonded composite structural joints

Thomas Keller, Anastasios Vassilopoulos

Constant amplitude fatigue loading spectra stand for only a small percentage of the real loading of a structure, although they can be used to investigate the fatigue and fracture behavior of structural elements. The fatigue and fracture behavior of adhesiv ...
