Influence of FRP anchors on FRP-to-concrete bonder interfaces

open access: yes, 2015
Existing reinforced concrete (RC) structural members such as beams, columns and joints can be strengthened and repaired with externally bonded high-strength and light-weight fibre-reinforced polymer (FRP) composites. The effectiveness of such strengthening can, however, be limited by premature debonding of the FRP at strains well below the strain ...

Characterization of Shear Strength of FRP Anchors

open access: yesMATEC Web of Conferences, 2018
A critical performance aspect of FRP retrofitted concrete elements is the bonding of the FRP sheet to the concrete surface. In general, the performance is limited by the debonding of the loaded FRP sheets from the concrete surface.

Cálculo en agotamiento de secciones de fábrica reforzadas a flexión con láminas de FRP

open access: yesInformes de la Construccion, 2015
Las estructuras de fábrica apenas tienen capacidad para resistir tracciones lo que las hace vulnerables ante acciones desestabilizantes de tipo accidental, como terremotos, o cuando sufren daños que alteran su geometría, por ejemplo, por asientos ...

Role of Fiber Sizing in Interfacial Relaxation, Water Uptake and Fatigue Properties of Acrylic‐Matrix Composites

open access: yesPolymer Composites, EarlyView.
Characterisation of glass fibre reinforced acrylic with acrylic‐tailored or multi‐compatible sizing agents. ABSTRACT Fiber‐reinforced infusible acrylic monomer resins are of interest as recyclable alternatives to epoxy and other thermoset resin composites, but the novelty of these resins causes published studies on acrylic‐matrix composites to often ...

FRP-strengthened RC slabs anchored with FRP anchors

open access: yes, 2015
Existing reinforced concrete (RC) structure can be strengthened upon the addition of externally bonded high-strength light-weight fibre-reinforced polymer (FRP) composites. An abundance of research over the last two decades has established the effectiveness of the externally bonded FRP via extensive experimental testing.

Synthesis of Poly(Itaconate)s With High Monomer Conversion Applying Emulsion Polymerization

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1284-1296, 15 March 2025.
Itaconic acid and its derivatives are a promising and bio‐based substitute for oil‐based polymers such as acrylates. In this study, the optimization of polymerization of itaconic acid esters is described by applying emulsion polymerization leading to high reaction conversions and low residual monomer contents. ABSTRACT Itaconic acid and its derivatives

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Low‐Cost Ambient Pressure Drying Approach for Highly Porous Nanomaterial Structures

open access: yesSmall Methods, EarlyView.
We propose a simple, low‐cost method to dry highly porous nanomaterial structures at ambient temperature and pressure. Using low surface tension solvents, this technique minimizes capillary forces, preventing pore collapse and material shrinkage. This bypasses the need for expensive and size‐limiting critical point drying, enabling scalable production ...
