“…As is well known, VE is very resistant to chemicals because of its unique molecular structure. , To our knowledge, there are few reports on improving the significant properties (mechanical, thermal, flammability, biocompatibility, and fire hazard analysis) of polymer blends made from epoxidized vegetable oil (EVO) and VE resin − for which most of the EVO they used has already been modified using acrylic acid, whereas there is a vast literature on blending DGEBA epoxy resin with EVO. In this study, we intentionally avoid modification of ECO to retain its eco-friendly property, and acrylic acid has been reported to cause acute toxicity to humans as disclosed by the Hazardous Substance Data Bank (HSDB). , Furthermore, due to the complicated structure of vinyl-based resins and the fact that most fillers and additives reduce their mechanical strength, few researchers are interested in enhancing their biocompatibility.…”

In this work, we investigated the influence of a novel green flameretardant thermoset complex matrix resin, VEECO, produced by thermoset blending of epoxidized corn oil (ECO) with a vinyl ester (VE) resin. The new polymer blend was made with the ECO content at an optimal amount of 15%. After characterization, it was discovered that the VEECO15 blend cured at 8 h had its glass transition improved by 6.38%. Regarding its mechanical properties, the improvements were as follows: flexural strength, 19.36%; modulus, 123.53%; and impact energy, 29.08%. The flammability property for the heat release rate was improved by 20.62% and, most importantly, emissions of CO and CO 2 were reduced by 62.73 and 49.34%, respectively, demonstrating its potential for sustainability. As a result of the proposed synthesis mechanism, the hydrogen bonding suggests the introduction of ECO as a biobased polymeric material. Overall, the polymer blend offers a new source of hybrid eco-thermoset resin that could mitigate the increasing consumption and environmental impact of BPA-based thermoset polymers. This material is expected to be a potential source of sustainable composites for a rapidly growing carbon-free society and eco-friendly urban development.

“…Sandwich panels with metal faces and foam cores are very often used as lightweight structures in shipbuilding applications [1][2][3][4][5], especially because of their performance on light weight and high rigidity. In the shipbuilding industry, the application of polymeric sandwich-type composites is constantly evolving, introducing into their composition new basic materials such as: fibers, resins, adhesives, cure accelerators, additives, etc.…”

A study on the static analysis of a naval panel made of composite sandwich materials is presented. By using FEM, the modeling of a naval floor with a length of 5 m and a width of 2.5 m is performed. Two distinct cases, have been performed: the first model consists of the plate and stiffeners made of steel and the second model concerns a panel made of composite material sandwich type steel / SANFoam103 / steel, and the stiffeners made of steel. A parametric study has been performed. The thickness of the steel faces have 6 mm, and for the core of SANFoam have been selected the thicknesses 5 mm, 10 mm, 20 mm, 40 mm.

“…Combining these two material characteristics creates a sandwich effect that provides a very efficient ratio of stiffness-to-weight [3,4,5], which is an important characteristic for light structures in the ship's construction [6]. In terms of the development of SPS for ship structure, several core materials have been analyzed, such as the combination of unsaturated polyester resin (UPR) with talc powder [7], bio-resin using vinyl ester and vegetable oil [8,9], UPR with a clamshell powder [10], UPR with an eggshell powder [11], epoxy resin [6], and polyurethane elastomer (PU) [12,13,14]. Steel faceplates and room temperature cured polyurethane elastomer core are commercial materials of SPS for ship structure [2,15].…”

A lightweight sandwich plate system (SPS) consisted of steel faceplate and polyurethane elastomer composite cores have excellent potential to be applied on the ship structure. Steel faceplate and polyurethane elastomer (PU) cores are frequently applied, but PU has a relatively high material cost. More economical material can be achieved by combining PU with fiberglass as a fiberglass reinforced polyurethane elastomer (FRPU) composite. In this study, the sandwich consisting of steel faceplate and FRPU composite core material is applied in the tanker side hull by investigating the structural performance and weight saving analysis using finite element analysis (FEA). Four sandwich side hull models using different stiffener configurations are compared with the conventional stiffened plate model. The result shows the promising SPS application in terms of structural strength and weight savings. The remarkable stress reduction, deformation, and structural weight reduction due to SPS application are discussed. Therefore, its weight reduction can increase the ship payload so that ship operations will be cost-effective.
