Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

Polymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

Polymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.

Experimental and Modeling Investigation of Seawater Hydrolysis Effects on Aramid Fiber Rupture Behavior

Journal of Polymer Science, EarlyView.
Hydrolytic aging in seawater produces markedly different mechanical responses among commercial Aramid fibers. While some fibers exhibit progressive degradation, others maintain stable or even improved tensile behavior. Experimental yarn‐scale testing combined with mathematical degradation modeling and Arrhenius‐based lifetime prediction provides new ...

High energy ballistic and fracture comparison between multilayered armor systems using non-woven curaua fabric composites and aramid laminates

Journal of Materials Research and Technology, 2017
For personal protection against high kinetic energy projectiles, multilayered armor systems (MAS) are usually the best option. They combine synergistically the properties of different materials such as ceramics, composites and metals. In the present work,

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Ballistic composites – protecting the protectors

Reinforced Plastics, 2017
It seems scarcely credible that thin polymer fibers, bound together in resin, can stop projectiles ranging from a hand-gun bullet to a high-power rifle round, but they can and have done so, saving many lives in the process. Composite body armor protects a wide range of civilians from security guards to police officers and from bailiffs to VIPs.
