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 ...

Non-proportional deformation paths for sheet metal: experiments and models [PDF]
, 2009 For mild steel, after significant plastic deformation in one direction, a subsequent deformation in an orthogonal direction shows a typical stress overshoot compared to monotonic deformation. This phenomenon is investigated experimentally and numerically

Polymer Engineering &Science, EarlyView.Mechanical recycling process and chemically recycled commercial blend pellets. ABSTRACT From 2030, in line with the new directive issued by the European Union, manufacturers of plastic beverage bottles will have to include at least 30% recycled plastic, calculated as an average for all bottles placed on the market in each Member State. In this context,

Recycling‐Induced Changes of Molecular Weight and Structural Properties in PET Monopolymer Blends
Journal of Polymer Science, EarlyView.The present study investigates the molecular weight, thermal, rheological, and mechanical properties of polymer blends of high and low molecular weight polyethylene terephthalate (PET) components. The research reveals that extrusion processing influences chain scission and chain extension, inhibiting the broadening of the molecular weight distribution ...

Conjugated Polymers Engineered for Flexible/Stretchable Electronics
Journal of Polymer Science, EarlyView.This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.
