Influence of process parameters on interlayer interface mechanical properties of 3D printing fiber reinforced concrete

open access: yesMaterials & Design
The layer-by-layer deposition in concrete 3D printing creates weak interlayer interfaces, posing risks to structural integrity. This study systematically investigates the effects of printing parameters (layer height, speed, interlayer time intervals) and

Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

open access: yesPolymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...
