Structural Adhesives in Laminated Glass
Research Guide
What is Structural Adhesives in Laminated Glass?
Structural adhesives in laminated glass refer to advanced interlayers like SentryGlas (SGP), ionoplasts, and hybrids that enhance mechanical performance over traditional PVB in structural glazing applications.
Research focuses on SGP's superior shear transfer, creep resistance, and post-breakage capacity compared to PVB. Key studies analyze failure modes in annealed glass/SGP beams (Belis et al., 2008, 101 citations) and interlayer properties (Fors, 2014). Over 20 papers from provided lists examine these in facades, BIPV, and blast loading.
Why It Matters
SGP interlayers enable load-bearing glass facades in high-rise buildings, as shown in Belis et al. (2008) where residual capacity post-failure supports structural integrity. In BIPV systems, adhesives like those in Kuhn et al. (2020, 336 citations) allow integrated photovoltaics on curved surfaces. Blast-resistant glazing relies on interlayer peel strength, per Larcher et al. (2016, 77 citations), expanding glass use in secure architecture.
Key Research Challenges
Creep in Ionoplast Interlayers
Ionoplasts like SGP show lower creep than PVB but long-term deformation under sustained loads remains uncertain. Belis et al. (2008) highlight residual capacity drops in beams. Fors (2014) notes experimental variability in shear modulus.
Peel Strength Post-Failure
Adhesive delamination reduces post-breakage ductility in laminated panels. Bedon (2017) identifies fire-induced peel failures in structural glass. Larcher et al. (2016) report blast testing inconsistencies.
Non-Ideal Restraint Buckling
Adhesive joints in glass walls cause shear buckling under non-ideal supports. Bedon and Amadio (2016, 50 citations) propose unified verification methods. Santo et al. (2020) analyze lateral-torsional buckling in beams.
