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

Fire 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 ...

Biaxial failure response of composite laminates

, 2017
The increasing applications of composite materials in many complex structures from aircraft fuselage to high performance automobiles could result in multi-axial stresses on the equipment surface during the operating processes.

The Binding of Pentadiyl‐α,ω‐Bis(Dimethyldodecylammonium), a Cationic Gemini 12‐5‐12 Surfactant to Conjugated Carboxylates as Organic Counterions

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The critical micelle concentration (CMC) values of the cationic gemini surfactant pentadiyl‐α,ω‐bis(dimethyldodecylammonium) bromide depend on the hydrophobicity of added conjugated organic carboxylate anions. Nine conjugated counterions, present as sodium salts of organic acids, were studied to expand the correlation to the counterion ...

Finite Element Analysis of Electrospun Nanofibrous Mats under Biaxial Tension

, 2018
Due to the non-uniform material properties of electrospun nanofibrous mats and the non-linear characteristics of single fibers, establishing a numerical model that can fully explain these features and correctly describe their properties is difficult ...

Mineral profile of cocoa powder: Analytical approach in commercial samples

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Cocoa powder is widely used in the food industry and has high nutritional value due to its composition, including minerals. The main factors related to the presence of minerals in cocoa powder are soil, processing, and cultivation practices.

A biaxial thermomechanical disk test for glassy polymers

, 1997
Failure criteria for polymers need to include effects from the stress state. For this reason, biaxial test results are of interest. However, biaxial test methods usually require expensive equipment.

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, EarlyView.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...
