Enhanced Gamma Radiation Shielding Using Epoxy Quartz Fabric Composites Reinforced With CoCl2 Microparticles

Advanced Engineering Materials, EarlyView.
The growing demand for lightweight, nontoxic, and multifunctional gamma shielding materials has intensified efforts to find alternatives to conventional lead and aluminum‐based protectants. In this work, we develop epoxy quartz fabric composites reinforced with cobalt chloride (CoCl2) microparticles, fabricated via hand lay‐up with varying filler ...

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

Advanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Damping Property of Fabric Bending Vibration.

Sen'i Kikai Gakkaishi (Journal of the Textile Machinery Society of Japan), 1996
目的 : 最終的には衣服の外観美を客観評価するため, 布の曲げ変形に基づく振動現象について詳細に検討し, 振動減衰特性を表す振動パラメータを見出す.成果 : (1) 布の振動減衰挙動は布の粘弾性抵抗係数が無視でき, 繊維素材, 糸や布の構造にかかわらず, 減衰が初期振幅の約1/5に至るまでは減衰曲線は2段階の直線になる. (2) 振幅が小さい場合, 布の内部摩擦は糸―糸間および繊維―繊維間の摩擦の2つに分けられる. (3) 布の曲げ振動パラメータのうち, 第1段直線部の振幅減衰量△d1は布の純曲げ特性および糸―糸間の摩擦に関連している.第2段直線部の振幅減衰量△d2は糸の構造および繊維―繊維間の摩擦に関連している.第1段階の振動持続時間S1は減衰の主要因摩擦項が糸―糸間の摩擦から繊維 ...

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs

Advanced Engineering Materials, EarlyView.
This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Bending, shear, and compressive properties of three- and five-layer cross-laminated timber fabricated with black spruce

Journal of Wood Science, 2020
Cross-laminated timber (CLT) is an innovative engineering wood product made by gluing layers of solid-sawn lumber at perpendicular angles. The commonly used wood species for CLT manufacturing include spruce-pine-fir (SPF), douglas fir-larch, and southern

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

Towards mechanomagnetics in elastic crystals: insights from [Cu(acac)$_2$]

, 2019
We predict that the magnetic properties of \cuacac, an elastically flexible crystal, change dramatically when the crystal is bent. We find that unbent \cuacac\ is an almost perfect Tomonaga-Luttinger liquid.
