Abstract
The laminated glass systems are regarded as hybrid polymer–glass composites where the viscoelastic behavior of polymer interlayers mostly controls mechanical response. These interlayers (polyvinyl butyral (PVB), ionoplast, ethylene-vinyl acetate (EVA), etc.) have time-, temperature- and rate-dependent properties which significantly affect shear transfer, energy dissipation, and fracture resistance. But the baseline polymer-relevant processes at the molecular and interfacial level are to a large extent unknown [1].
This review provides a materials-focused viewpoint on the polymer interlayers in laminated glass systems, with a focus on viscoelastic constitutive behaviour, molecular mobility, and interfacial adhesion. The effects of polymer composite (chain dynamics and glass transition behaviour) on creep, stress relaxation, and thermomechanical behaviour are discussed in detail. Advanced modeling strategies such as nonlinear viscoelastic formulations and probabilistic frameworks are reviewed for accurate prediction of time- and uncertainty-dependent material behavior. In addition, the contribution of polymer interlayers to post-fracture load transfer and the overall composite reliability are also studied from a materials science perspective.
As well, new progress on nanocomposite interlayers, bio-based polymers, and data-driven materials modelling techniques is discussed. Major research gaps in multi-scale characterization and long-term performance prediction are highlighted, providing critical guidance for the design of high-performing, durable, and sustainable polymer–glass composite material systems [2]. Macroscopic properties can be traced back to molecular chain dynamics and relaxation spectra.
