“…For the above-mentioned uses, polymer composites made with synthetic or else natural fibers were widely used. Composite structures can benefit from the superior stiffness and strength of synthetic fibers (such as basalt, Kevlar, glass, and carbon) when used for loadbearing purposes [4][5][6]. Glass-fiber reinforcement has outstanding mechanical and thermal qualities that are ideal for aeronautical use.…”

Reinforcing fibers, nanofillers, matrix materials, and manufacturing techniques all have a role in the mechanical characteristics of hybrid composites. MWCNTs-reinforced E-glass/Kevlar/epoxy composites are appropriate fillers for structural applications. The impact of different concentrations of MWCNT fillers (0.4%, 0.8%, and 1.2% wt) on the mechanical characteristics of hybrid composites has been studied. Tensile and bending strength, as well as hardness, were measured in compression-molded composites. The effects of compression pressure, mold temperature, and applied pressure on hybrid (0.8% MWCNT) were investigated. When it came to composite tensile and bending strength, compression pressure was the most important factor, closely succeeded by mold temperature and pressure period. Compression molding were optimized, resulting in a tensile strength of 183 MPa, a bending strength of 158.3 MPa, and a hardness value of 23.8 HV.

“…[16] Compression specimens in the shape of a short column cylinder of size 30 mm in diameter and 60 mm in height as specified by ASTM D695 standard where the diameter to height ratio of 1:2 was followed in the preparation of test specimens. [22] For the fabrication of pure UP resin and UP-MMT nano-clay composite samples, an open mold in the shape of a cylindrical tube was used as shown in Figure 2. Once the UP resin has been mixed with MEKP to prepare the matrix, the matrix was poured into the mold and kept at a level at least 3 mm higher than the desired specimen height.…”

The effect of montmorillonite (MMT) nano-clay as reinforcement in unsaturated polyester resin (UP) matrix composite was investigated under compression loading to explore the impact of MMT nano-clay wt% in the compressive behavior of UP-MMT nano-clay composite. UP-MMT nano-clay composite samples were prepared with a varied filler content of 0.5 to 3 wt% using dualmixing methods, which are mechanical stirring and ultrasonic agitation.Static uniaxial compression tests were conducted using cylindrical-shaped samples to obtain the compressive behavior of the UP-MMT nano-clay composites. The results of experimentation record a considerable improvement in compressive characteristics of UP-MMT nano-clay composites compared to pure UP matrix. The UP-MMT nano-clay composite samples were viewed under transmission electron microscope (TEM) to know the dispersion of MMT nano-clay in the composites. The nano-platelets were well dispersed and intercalated in the UP-MMT nano-clay composite samples below 1 wt% MMT nano-clay loading. The optimum wt% of MMT nano-clay in the UP-MMT nano-clay composite for improved compressive stress at yield and modulus were noted as 0.60 and 0.61 wt% respectively. Moreover, a mathematical model using Halpin-Tsai-Jumahat equations was utilized to predict the compressive properties of UP-MMT nano-clay composites, which are in closer agreement with the experimental results.

“…They offer superior strength and low weight compared to conventional materials and simple composite materials [4][5][6]. The properties exhibited by every composite material depend on factors such as the property of the individual components, the composition of the materials, the manufacturing methods adopted, the orientation of the reinforcement fibers, pre-processing and post-processing techniques, and the presence of defects [7][8][9][10].…”

The hygroscopic properties of natural fibers tend to degrade the mechanical properties of composite materials. It is essential to investigate the influence of water absorption behavior on the mechanical properties of hybrid composite materials. In this study, hybrid laminate materials consisting of two different reinforcement materials, i.e., Kevlar fibers and jute fibers in the same layer, are considered. Hybrid laminates that have four different weaving patterns: plain weave, basket weave, twill weave, and the satin weave, are tested for their water absorption characteristics. The jute fiber is a naturally extracted fiber that is subjected to chemical treatment. A comparison of mechanical properties before and after treatment of the jute fibers is carried out. Mechanical properties such as tensile strength, compressive strength, flexural strength, impact strength, and hardness are tested. It is found that the mechanical properties improved after the treatment of the jute fibers. The twill weave pattern exhibited negligible defects compared to its counterparts. Chemical treatment of the jute fibers enabled less water being absorbed into the hybrid laminate materials. Mechanical properties improved after using chemically treated jute fibers as the reinforcement material in the hybrid laminate materials. It is concluded that the twill weave pattern and chemical treatment of the natural fibers improved the mechanical properties of the hybrid laminate materials.
