“…This is because of discriminated reinforcement phases and sudden changes in the load propagation route. [ 34 ] Compare to all of the composite designation, EO2 shows the higher load due alternate stacking sequences of surface‐treated Kevlar fiber and brass wire mesh, which develops better adhesion between the two ply because of the silane surface treatment.…”

Kevlar fiber and brass wire mesh reinforced with cubic boron nitride (CBN) particle-toughened epoxy composites are investigated in this study. This study aims to determine the hybrid composite's mechanical and drop load impact behavior, as well as the effect of surface treatment on the lamina delamination resistance and load bearing phenomenon. The composite laminates were fabricated by hand layup process and characterized according to ASTM standards. The tensile, flexural, Izod impact, ILSS, and hardness testing results shows that adding 35 vol% reinforcements and 3.0 vol% CBN particles indicates the

“…Compared with the Normal specimen, the average ultimate load of the Steel Strand specimen increased by 13.3% and the deflection increased by 5%. Due to the larger specific surface area of the steel-strand grid [ 32 ] and the treatment with polyurethane solution, the bonding strength is greater and the ultimate load is increased. The average ultimate load of the C-80-1 specimen reinforced by the carbon fiber grid is 47.3% higher than that of the Normal specimen.…”

In view of the problems of traditional repair materials for anchorage concrete of expansion joints, such as ease of damage and long maintenance cycles, the design of polyurethane concrete was optimized in this article, which could be used for rapid repair of concrete in anchorage zone of expansion joints. A new type of carbon fiber grid–polyurethane concrete system was designed, which makes the carbon fiber grid have an excellent synergistic effect with the quick-hardening and high-strength polyurethane concrete, and improved the flexural bearing capacity of the polyurethane concrete. Through the four-point bending test, the influence of the parameters such as the number of grid layers, grid width, and grid density on the flexural bearing capacity of polyurethane concrete beams was tested. The optimum preparation process parameters of carbon fiber grid were obtained to improve the flexural performance of polyurethane concrete. Compared with the Normal specimen, C-80-1’s average flexural strength increased by 47.7%, the failure strain along the beam height increased by 431.1%, and the failure strain at the bottom of the beam increased by 68.9%. The best width of the carbon fiber grid was 80 mm, and the best number of reinforcement layers was one layer. The test results show that the carbon fiber grid could improve the flexural bearing capacity of polyurethane concrete. The carbon fiber grid–polyurethane concrete system provides a new idea for rapid repair of the anchorage zone of bridge expansion joints, and solves the problems such as ease of damage and long maintenance cycles of traditional repair materials, which can be widely used in the future.

“…Sandwich structures, which are a kind of laminated composites, consist of thin, stiff, and strong face sheets and light and thick core material. [1] Sandwich structures with carbon fiber-epoxy face sheets and polyvinyl chloride (PVC) foam core material are known for their superior strength, flexural stiffness, and low weight. The main disadvantage of these sandwich structures is low impact resistance due to thin composite face sheets.…”

Sandwich structures with carbon fiber-epoxy face sheets and polyvinyl chloride foam core material are known for their high strength and flexural stiffness despite their low weight. However, the structural response, in terms of crush strength, of the particles added sandwich structures are not very well known under impact loading conditions. In this study, the impact resistance and damage characteristics of particle added low weight composite sandwich structures were investigated with a low-velocity drop weight impact test device. Boron carbide (B 4 C) particles, which had excellent hardness, thermoelectric, and radiation absorbing characteristics, were used as an additive for the epoxy matrix. For this purpose, 2%, 5%, and 10% by weight additives were mixed into the epoxy matrix and sandwich structures were produced with hand lay-up followed by vacuum bagging method. All configurations were subjected to low-velocity drop weight impact test at three different energy levels (10, 17.50, and 25 J). The results obtained from the experiments and the images of the post-impact damage of the sandwich structures were presented comparatively. According to the test results, configurations containing 10% boron carbide (B 4 C) additive has shown the best performance in terms of resistance to impact load.
