An Integrated Statistical and Machine Learning Framework for Predicting the Dry Sliding Tribological Behavior of CFRP and GFRP Composites Under Environmental Aging and Loading Conditions

Polymer Composites, EarlyView.
The graphical abstract presents the experimental and data‐driven framework used to investigate the dry sliding tribological behavior of CFRP and GFRP composites. The effects of seawater, engine oil, diesel fuel, aging time, and normal load on the specific wear rate (SWR) and coefficient of friction (COF) were evaluated using pin‐on‐disc tests, ANOVA ...

Fungal‐Assisted Recycling of Carbon‐Fiber‐Reinforced Polymer Waste via Mechanistically Informed Hybrid Pathways

Polymer Composites, EarlyView.
Fungal‐assisted recycling of carbon‐fibre reinforced polymer waste. ABSTRACT Epoxy‐based carbon‐fiber‐reinforced polymer (CFRP) composites are increasingly used in high‐performance applications, yet their highly cross‐linked and chemically resistant matrices remain difficult to recycle sustainably.

Fiber‐Reinforced Bio‐Epoxy Composites: Degradation Mechanisms in Saline Environment

Polymer Composites, EarlyView.
Constituent level degradation of bio‐epoxy composites after saline aging. ABSTRACT This study examines the degradation behavior of bio‐epoxy composites reinforced with glass, basalt, carbon, and flax fiber yarns in a simulated saline environment. Fiber yarns and composite samples were exposed to 3.5% NaCl solution at 60°C for up to 3000 h.
