“…Therefore, in the FRP grid design process, the choice of fiber type should be considered more than the sheet type and process method. GFRP has lower tensile strength but higher flexural strength compared to CFRP [ 27 ]. Therefore, a hybrid laminated grid combining CFRP and GFRP is required when manufacturing the FRP grid to be used for structures that require bending strength.…”

In the present study, fiber-reinforced plastics (FRP) grid-reinforced concrete with very rapid hardening polymer (VRHP) mortar composites were fabricated using three types of design methods for the FRP grid (hand lay-up method, resin infusion method, and prepreg oven vacuum bagging method), along with two types of fibers (carbon fiber and glass fiber) and two types of sheets (fabric and prepreg). The FRP grid was prepared by cutting the FRP laminates into a 10 mm thick, 50 mm × 50 mm grid. The tensile behavior of the FRP grid embedded in composites was systematically analyzed in terms of the load extension, fracture mode, partial tensile strain, and load-bearing rate. The CFRP grid manufactured by the prepreg OVB method showed the best tensile behavior compared to the CFRP grid manufactured by the hand lay-up and resin infusion methods. The load-bearing of each grid point was proportional to the height from the load-bearing part when reaching the maximum tensile load. In addition, finite element analysis was conducted to compare the experimental and analysis results.

“…Samples of selected composites were tested within the framework of the project which aimed at creating a footbridge with sandwich structure (Fig. 2) using the vacuum infusion technology, which is typical for production of yacht hulls, among other applications [8][9][10]. The implemented project [11][12][13] included a series of experimental, numerical and technological tests [14,15], which made it possible to monitor the entire process, from a preliminary concept to building a full-scale object.…”

The paper presents results of systematic tests of contraction and thermal expansion coefficients of materials based on polymer composites. The information on the above material properties is essential both at the design stage and during the use of finished products. Components for the samples were selected in such a way as to represent typical materials used for production of construction and moulding elements. The performed tests made it possible to monitor the analysed parameters at different stages of the technological process.

A metal-organic framework (MOF) formed between Zn and p-hydroxybenzoic acid (PHBA) is synthesized using a solvothermal method. These Zn-PHBA nanorods, which are inexpensive and suitable for mass production, are added as a flame-retardant into vinyl resin (430 LV, a material used in marine composites). Data from cone calorimetric test demonstrates that adding the Zn-PHBA nanorods to 430 LV significantly improves flame retardation and smoke suppression. At a high Zn-PHBA content of 10.0 wt%, the limiting oxygen index of 430 LV increases from 19.5% to 28.5%, and the material reaches the V-0 rating in vertical burning tests (UL-94). Moreover, the tensile and impact strengths of 430 LV containing 10 wt% Zn-PHBA as flame-retardant do not deteriorate and are even slightly improved. This work demonstrates that this MOF synthesized by a simple and efficient method may be used to produce nanocomposites with excellent flame retardation and mechanical properties, while keeping the material cost sufficiently low for marine applications.
