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.

Alternative aircraft fuels technology [PDF]

open access: yes
NASA is studying the characteristics of future aircraft fuels produced from either petroleum or nonpetroleum sources such as oil shale or coal. These future hydrocarbon based fuels may have chemical and physical properties that are different from present

Tensile and flexural behavior of synthetic and hybrid natural fiber composites for lightweight applications

open access: yesPolymer Composites, EarlyView.
Stress vs. displacement graph and microstructural analysis of composite materials. Abstract The growing demand for lightweight and sustainable materials has driven research into hybrid composites that combine synthetic and natural fibers. This study aims to investigate the tensile and flexural behavior of carbon fiber (CF) and glass fiber (GF ...

The development of an airborne instrumentation computer system for flight test [PDF]

open access: yes
Instrumentation interfacing frequently requires the linking of intelligent systems together, as well as requiring the link itself to be intelligent. The airborne instrumentation computer system (AICS) was developed to address this requirement.

Physics-informed transfer learning model for fatigue life prediction of IN718 alloy

open access: yesJournal of Materials Research and Technology
To address the challenges posed by inadequate data and data utilization in multiple scenarios of fatigue loading, a Physics-informed Transfer Learning (PITL) model has been developed to predict the fatigue life of IN718 superalloy.
