Continuous carbon fiber Additive Preforming and its application for the fabrication of epoxy composites

open access: yesPolymer Composites, EarlyView.
Flowchart illustrating the steps of Additive Preforming technology for fabricating epoxy‐carbon fiber composites by 3D printing. Abstract This study presents Additive Preforming, a novel technique for manufacturing continuous fiber‐reinforced polymer composites. The new technique consists of 3D printing continuous fiber filaments coated with a suitable

Failure analysis of angle‐ply thin woven GFRP composites under low‐velocity impact and low‐temperature

open access: yesPolymer Composites, EarlyView.
Abstract A comprehensive experimental and analytical study was conducted on quasi‐isotropic woven glass fiber‐reinforced polymer composites with a stacking sequence of [0°/±45°/90°]s, under low‐velocity impact at a low temperature of −50 °C. The results were compared to those at room temperature.

Unveiling aluminum diethyl phosphinate dual identity: Transfer from epoxy resins to glass fiber‐reinforced composites

open access: yesPolymer Composites, EarlyView.
Comparing resins with composites, different particle sizes of the flame retardant, and the impact of the flame retardant modes of action on different fire properties. Abstract This study examines the transfer of the flame‐retardant aluminum diethyl phosphinate (AlPi) from epoxy resins to composites and the impact of AlPi on fire behavior and fire ...

Mechanical performance of bio‐based fiber reinforced polymer composites: A review

open access: yesPolymer Composites, EarlyView.
Applications of bio‐based fiber reinforced polymer composites in various sectors. Abstract Natural fiber‐reinforced polymeric composites (NFRCs) offer a sustainable solution at the intersection of environmental consciousness and materials engineering. These composites address plastic pollution and industrial material demands by utilizing natural fibers

Paving the Way for Improved Representation of Coupled Physical and Biogeochemical Processes in Arctic River Plumes—A Case Study of the Mackenzie Shelf

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land‐to‐ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery.

Planting and replanting: Continuity and change over four decades of forest restoration in Himachal Pradesh, India

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
India has a long history of planting trees to restore ecosystem services providing an opportunity to evaluate long‐term ecosystem restoration processes. We show that these programs have shifted over time in response to public demands as well as through changes in the government's vision for forests.

Influence of AP Particle Size on Burning Characteristics of HMX/AP Propellants Supplemented with Fe2O3

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Nitramine propellants have attracted considerable attention in the domain of solid rockets and gun propulsion because of their energetic and smokeless features. Ammonium perchlorate (AP) is the widely used oxidizer in propellants owing to the excellent burning characteristics.
