Effect of Ti3C2Tx MXene Incorporation on the Mechanical Performance and Microstructural Characteristics of Bulk Molding Compound Composites

Polymer Composites, EarlyView.
Graphical overview of the preparation, mechanical performance and microstructural characterization of low‐content Ti3C2Tx MXene‐reinforced BMC composites. ABSTRACT Bulk molding compound (BMC) composites are widely used in engineering applications; however, improving their mechanical response through low‐content nanoscale modification remains ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Performance evaluation of thick carbon fiber‐reinforced laminates manufactured using six‐magnetron microwave system

Polymer International, EarlyView.
IM7/Cycom 5320‐1 unidirectional prepreg has been used to fabricate 64‐layer laminated composites. A custom‐built six‐magnetron microwave applicator and an autoclave were employed to manufacture the composite panels. Mechanical performance of the microwave‐cured composites has been juxtaposed to autoclave‐cured composites in terms of uniaxial tensile ...

Lightning electromagnetic emission location using arrival time differencing (LEELA): An introduction to the Met Office's next generation Very Low Frequency lightning location system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Brown–Proschan Repair Policy for Repairable Systems Using the Discrete Weibull Failure Distribution and Markov Chains

Quality and Reliability Engineering International, EarlyView.
ABSTRACT A repairable system operates under a maintenance strategy involving scheduled preventive maintenance (PM) and corrective repair actions following failures. This study develops an exact analytical methodology using Markov chains with discrete states and time to calculate the expected number of failures E[N(t)]$\mathop {\mathbb {E}}[N(t)]$ under

Weibull Variational Autoencoder for Remaining Useful Life Prediction

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Remaining useful life (RUL) prediction is a critical technology for preventing unexpected failures and reducing maintenance costs in modern industrial systems. However, traditional model‐based approaches are limited by the need for explicit mathematical modeling of degradation mechanisms, while data‐driven methods often require large‐scale ...
