“…The usage of natural fibers leads to adverse mechanical and electrical properties as a result of the mismatch with the hydrophobic polymer matrix. These limitations can be reduced by hybridization technique [36]. Friction and wear rate is typically affected by the properties of matrix and reinforcement materials, process opted for manufacturing, orientation and length of the fibers, conditions under which the components are operated as well as the sequence of stacking of the laminates.…”

Polymer composites reinforced with fibers have been consistently employed in applications involving friction in many industrial components. Though natural fibers possess many advantages, they absorb greater moisture and also their impact properties being quite low, ultimately degrades the mechanical properties. On the other hand, synthetic fibers offer greater specific strength, less density and extraordinary mechanical and tribological properties and hence substituted with many natural fibers. In this point of view, an effort has been made in this article to highlight the tribological behavior of a number of synthetic fiber reinforced polymer matrix composites modified by fillers to satisfy greater strength or modulus requirements.

“…2 For example, Valueva and Wu depending on the task made a composite with an AF volume fraction of 52–55% 3 and 65%. 4 A detailed study on this subject was conducted in the work, 5 where the authors investigated the stress-strain properties of the AF/ER composite with changes in the percentage composition of AF by mass of 30%, 35%, and 45%. As a result, the composite with 35% AF and 65% ER showed high tensile strength and hardness.…”

Polymer composites, in particular aramid-epoxy composites, are widely used in fields such as aerospace, transportation, electronics, etc. due to their excellent mechanical and dielectric properties. This article presents studies of modification and combined reinforcement on the mechanical properties of aramid-epoxy composites. The influence of matrix (epoxy resin) and reinforcing filler (aramid fabric) mass ratio and ways to increase strength characteristics and impact toughness of the composite were studied. Comparative results for composites made by vacuum forming and vacuum infusion methods are presented. Mass ratio of reinforcing filler and matrix varied in the range of 50:50%, 60:40%, 65:35%, and 75:25%. It was found that modifying epoxy resin with polyurethane rubber plasticizer, together with combined reinforcement of aramid fabric/aramid roving, resulted in composite strength up to 720 MPa and impact toughness of 426 kJ/m2. Modification of epoxy resin with tricresyl phosphate leads to composite strength up to 710 MPa and impact toughness of 475 kJ/m2. Thus, it is shown that modification and combined reinforcement of aramid-epoxy composites are the most effective methods to increase strength and adhesion to epoxy resin.

Natural fibers (NFs) and inorganic particles have been successfully grown in the polymer to enhance its properties. The basalt fiber (BF) and modified hydrotalcite (LDHs) reinforced epoxy resin matrix composites were prepared, and the effects of fiber and modified hydrotalcite (G-LDHs) on the microstructural characteristics of composites were investigated. Fourier transform infrared spectroscopy and X-ray diffraction were respectively used to analyze the structure of modified BF and G-LDHs, and thermogravimetric analysis was performed to study thermal stability. The mechanical properties of composites, including dynamic thermomechanical and tensile and flexural properties, were respectively studied by dynamic mechanical analysis (DMA) and universal testing machine. Experimental results show the successful synthesis of high-performance epoxy copolymers. The impact strength, tensile strength, and elastic modulus of EP/BF/G-LDHs respectively reached 7.07 kJ/m 2 , 20.52 MPa, and 2595 MPa when the content ratio of BF to hydrotalcite in the additive was 3:3. The DMA test showed that the glass transition temperature (T g ) value increased by 18.3 C, and the thermal stability of composite materials was improved. The storage modulus E 0 value increased by 268.04 MPa, and the stiffness of the epoxy material and the mechanical properties were also elevated. The TGA and DTG curves indicate that the cured composites also exhibit excellent thermal stability. The effect of g-LDHS particle size on the properties of composites was also discussed. Overall, the synergistic and complementary enhancement effect of the two materials is the best when the diameter of hydrotalcite is similar to that of BF, and the performance of the composite material is considerably improved.high-performance composites, mechanical properties, mechanical properties, thermal stability, thermogravimetric analysis | INTRODUCTIONEpoxy resin is one of the polymer materials with a long history and wide application.
