Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties

Macromolecular Rapid Communications, EarlyView.
A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Influence of Adding Cyclodextrin Derivatives on the Mechanical and Thermal Properties of Glassy Polymers

Macromolecular Rapid Communications, EarlyView.
Triacetylated γ‐cyclodextrin incorporated into poly(methyl methacrylate) primarily acted as a rigid filler and reinforced the matrix polymer, with the reinforcement behavior following the Guth–Gold equation. In addition, the glass transition temperature was maintained upon incorporation, indicating that the additive did not plasticize the polymer ...
