“…A pivotal facet of this study involves a meticulous comparative analysis, both before and after aging tests, juxtaposing the durability, optical performance, and aesthetic qualities of the nano-enhanced HPLs against a conventional standard REF HPL . The overarching aim is to ascertain the degree to which nanoparticle enhancement equips these laminates with the requisite durability and property enhancements, thus rendering them reliable and resilient for facade applications.…”

High-pressure laminates (HPLs) are widely utilized in interior applications but may have potential as exterior building facade coatings if suitably enhanced for weatherability. Nanoparticle additives are a promising approach to improving the durability and functionality of HPLs. This study aims to evaluate titanium dioxide (TiO 2 ) and silicon dioxide (SiO 2 ) nanoparticles incorporated into HPLs to determine if they impart properties for durable, functional exterior facades. Methods: HPLs were fabricated with 3.75 wt % TiO 2 and SiO 2 nanoparticles in the surface overlay. Industry-standard EN 438 tests characterized the quality, optical properties, and accelerated aging, including UV radiation, weathering, and thermal shocks. Properties were measured before and after aging to compare versus a standard HPL without nanoparticles. Nanoparticles not only increased initial solar reflectance but also caused color changes. After aging tests, nanoparticles did not sufficiently enhance durability compared to the standard HPL. While initial reflectance improved with nanoparticles, overall weatherability did not, indicating a need to optimize fabrication and nanoparticle selection. Although TiO 2 and SiO 2 nanoparticles increased initial HPL reflectance, the feasibility of durable facade coatings was not conclusively demonstrated. Further research should focus on ideal fabrication methods, nanoparticle types and concentrations, and performance in real-world conditions to facilitate adoption in building facade applications.

Carbon fiber reinforced aluminum laminates (CARALL) are often subjected to bending loads in actual working conditions, resulting in some imperceptible intra-layer or inter-layer damages, such as matrix cracking, fiber fracture and inter-layer delamination, which degrade the mechanical properties of the structure. In this paper, the bending performance and damage mechanism of CARALL are tested and simulated by finite element simulation. Firstly, the mechanical properties are analyzed by three-point bending test, and the fracture morphology of the specimen after failure is photographed by scanning electron microscope, and the failure damage state from the microscopic perspective is analyzed. Secondly, the VUMAT subroutine with built-in three-dimensional Hashin criterion is introduced into ababqus. By comparing the finite element simulation and experimental results, the rationality and accuracy of using VUMAT subroutine to predict the failure behavior of Al-CFRP-Al laminates are verified. The results show that during the bending failure process, the aluminum alloy layer suffered local damage, and the carbon fiber layer suffered a large area of damage. The layer near the indenter was subjected to large stress concentration during bending, resulting in intensified interlayer interaction and serious damage. The crack began to expand downward along the stress and gradually became smaller as it expanded. The research results provide basic data reference for the bending performance and damage mechanism of fiber metal laminates (FMLs), and have important engineering application value for the optimization design of related structures.
