“…Nevertheless, samples VE/BT and EP/BT did not exhibit the greatest elongation degree at σ max . The σ max results at 25 • C are in line with literature reports for materials strengthened with chopped fibre and powder fillers [16][17][18][19][20]. In theoretical considerations described in the literature, the worst strength properties have been seen for composites containing chopped or ground fibre and fibre mats providing the reinforced plastics with both spatial and in-plane isotropy [21][22][23][24][25].…”

The aim of this work was to obtain insulation composite anchors based on basalt textile-reinforced vinylester and epoxy resins for fixing heavy building elevation cladding. It concerns the problem of applying materials not originating from wood, construction steel or concrete in the building industry. So far, the application of polymeric materials, including polymeric composites, in construction has been limited to paints, varnishes and glues, and the use of engineering polymers as building materials has been limited. This article presents a study on the influence of the type of basalt reinforcement (in the form of textile, chopped fibre and powder) on the mechanical and functional properties of vinylester and epoxy compositions towards potential applications as construction anchors to fasten building facades. Based on an analysis of the experimental results, a material was selected for the production of novel construction anchors. The results reported here constitute an introduction to further considerations related to the applications of vinylester resin/basalt and epoxy resin/basalt composites as construction materials alternative to commonly used steel and aluminium.

Basalt/Glass Fiber Polypropylene Hybrid Composites: Mechanical Properties at Different Temperatures and under Cyclic Loading and Micromechanical Modelling

2021

Basalt/glass fiber polypropylene hybrid composites were developed as subjects of investigation, with the aim to characterize their properties. An injection molding machine was used to produce the test samples. The following three different tests, at various specimen temperatures, were conducted: tensile test, three-point flexural test, and Charpy impact test. To determine fatigue behavior, the samples were uniaxially loaded and unloaded. Mechanical hysteresis loops were recorded and the dissipation energy of each loop was calculated. To determine the adhesion and dispersion between the fibers and the matrix, the fractured surfaces of the various specimens, after the tensile test, were investigated using a scanning electron microscope. The results show that the production of a composite with both basalt and glass fibers, in a polypropylene matrix with maleic anhydride-grafted polypropylene, can be successfully achieved. The addition of the two types of fibers increased the tensile strength by 306% and the tensile modulus by 333% for a composition, with 20% by weight, of fibers. The material properties were estimated with the help of a simulation software, and validated with a FEA. A satisfactory correlation between the simulation and measurement data was achieved. The error lays in a range of 2% between the maximum stress values. At a lower strain (up to 0.02), the stress values are very well matched.

On the other hand, Plappert et al (2020) achieved a 60% fiber volume density with a single ramp of temperature increase. The process was performed as follows: Increasing the temperature from ambient to 120C in 30 min.…”

Developments for improving the effectiveness of the composite structures strongly depend on the manufacturing methods. Additionally, the composite manufacturers have put effort into cost-effective and automated fabrication with mechanization. Controlling the imperfections is also an important consideration for the production. This study presents several manufacturing methods for fiber-reinforced polymer composites. It also draws attention to novel techniques that use advanced technology required for the developed composite designs. Besides the conventional methods such as hand lay-up, vacuum bag, resin transfer molding, resin infusion, and autoclave, the advances in hot press molding, pultrusion process, and automated lay-up method were indicated. Moreover, the methods making difference for the hybrid composite designs such as the same qualified resin transfer molding and automated stitching processes were introduced. The advantages and limitations were indicated for the manufacturing methods and the usage purposes were addressed.
