Research progress in lignin/vanillin-based vitrimer and recyclable carbon fiber composites

Cailiao gongcheng
Thermosetting resins are widely used in the composition of carbon fiber-reinforced polymers （CFRPs）， which are insoluble and non-melting after curing， making thermosetting resins and carbon fibers （CFs） difficult to recycle and reuse.Vitrimer has the ...

White‐Light‐Mediated Imidazole Catalysis Toward Terpene‐Based Thermosets

Angewandte Chemie, EarlyView.
White‐light irradiation enables the photoinitiator‐free curing of fully bio‐based terpene epoxy–anhydride systems. A light‐induced switch in epoxide ring‐opening selectivity leads to colorless, transparent thermosets with enhanced thermomechanical performance, revealing an unexpected pathway for sustainable terpene‐based network formation.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Evaluation of impact strength of heat cure and chemical cure acrylic resin denture base material

Erbil Dental Journal, 2022
Background and Objective: Thermal and self-curing acrylic resins are widely used in dentistry because they are biocompatible, have no flavour or odour, have good thermal properties and polishing capacity, and are simple and quick to apply. As a result

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
