Experimental and numerical study on CuO/ZnO-modified aramid fabric for ballistic and UV radiation protection

Polymer Testing
Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical ...

Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

Polymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.
