Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

open access: yesFire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Flexural Behavior of Prestressed Girder with High Strength Concrete

open access: yes, 2006
The advantages of using high strength concrete (HSC) have led to an increase in the typical span and a reduction of the weight of prestressed girders used for bridges.

A talus rock glacier in Nantlle Valley, North Wales

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

open access: yesMacromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...

Experimental Comparative Analysis of Hole‐Making Strategies and Cutting Parameters on Flexural Properties and Induced Delamination in S2 Glass and Basalt Fiber‐Reinforced Polymers

open access: yesPolymer Composites, EarlyView.
Hole‐making strategy and machining parameters influence delamination and hole quality in S2‐glass and basalt FRP composites, which subsequently affet flexural performance. Improved hole integrity leads to enhanced structural performance during three‐point bending.

Second‐Life Thermoset Manufacturing via Mild Solvolysis of Epoxy‐Matrix Composites and Wet‐Laid Mat Production

open access: yesPolymer Composites, EarlyView.
From end‐of‐life pultruded CFRP profiles (1) to second life composites (7) through mild solvolysis (2,3), wet‐laid nonwoven mat fabrication (4), resin impregnation (5), and compression molding (6). ABSTRACT The growing use of carbon fiber–reinforced thermosets has led to the accumulation of significant composite waste, posing environmental and economic

Quantitative Evaluation of Surface Whitening Mitigation via Thermal Annealing in Carbon Fiber/Polyphenylene Sulphide Thermoplastic Composite Laminates

open access: yesPolymer Composites, EarlyView.
Mitigation of surface whitening in CF/PPS laminates via thermal annealing and quantitative image‐based assessment. ABSTRACT Surface whitening is a manufacturing‐induced surface defect in thermoplastic composites, resulting from non‐uniform shrinkage and near‐surface resin instability during cooling.
