The primary goal of this study is to determine how well the addition of alumina trihydride (ATH) fillers affects the material properties of hybridised polyester nanocomposites using a weaved jute fibre. The manual lay-up approach was used to create the hybrids, using control variables: (i) ATH filler weight ratio, (ii) stitched jute fiber width, and (iii) amount of stitched jute sheets, altogether at tierce dissimilar stages, to fulfil the goals of this study. By using L9 (33) symmetrical layout, 9 samples were constructed and tested in accordance with the ASTM specification. According to the study by Grey, biocomposites with 6% ATH dust and 250 gsm of weaved jute filaments in tierce have such a satisfactory outcome. Inclusion of dietary fibres to pure synthetic materials improved aggregate material properties. Even as fibre as well as pitch meditations raised, greater power was mandatory to fracture the fibres among matrices as well as their reinforcements. [ABSTRACT FROM AUTHOR]

Stir casting was utilized to generate the composites. The AA 2618–10wt% zirconium carbide 10wt% rice husk ash hybrid composite had the highest hardness value. In comparison to pure AA 2618, it had a 72% increase. The rule of mixture was used to compute theoretical density, whereas the Archimedes rule was utilized to evaluate real density. For AA 2618, AA 2618/zirconium carbide, and rice husk ash hybrid composites, simple carbide inserts were used for turning. Surface roughness, metal removal rate, and tool wear were among the numerous responses examined. RSM was utilized to analyze and optimize the test outcomes. Feed rate was the most critical issue for surface roughness and material removal rate. Tool wear was shown to be most strongly controlled by tool speed, whereas metal removal rate was found to be least significantly influenced by the weight percent of reinforcement.

In this research work, an attempt was made to reinforce AA7168 aluminium alloy with Boron Carbide (B4C) and Silicon Carbide (SiC) through compos casting technique. Tribological test were performed by varying weight percentage (3, 6, 9, 12%), Load (10, 20, 30, 40 N), Sliding velocity (10, 20, 30, 40 m/s) and sliding distance (1000, 2000, 3000, 4000 m). The results revealed that the wear resistance increases with addition of reinforcing particles until a saddle point of 9 wt.% owing to the formation of mechanical mixed layer. At 12%, the wear resistance reduces because of the clustering of particles. Because of the hardness of the particles, the coefficient of friction increases with increasing weight percentage. From Taguchi approach, it was revealed that percentage reinforcement was most influential factor followed by load, sliding velocity and sliding distance. The addition of particles increases the hardness and tensile strength due to the hall petch effect and orowan strengthening. WASPAS technique was utilised to optimise the input variables.

The manufacture and investigation of the characteristics of nanocomposites with nanoparticles are made by the sol-gel technique. It comprises two substances (aluminium oxide-silicon oxide), as well as the influence of such particles on the mechanical characteristics of a polymeric matrix is described in this study. Tensile, bending, and hardness tests were utilized to assess the mechanical characteristics of the hybrid material. The evaluation results of composite nanoparticles revealed a clear dispersion of chemical components among aluminium oxide and calcium oxide, softness in particulate matter during crystallization at high and low temperatures, the initiation of various nanostructures forms, and distinct stages of an alumina particle. When compared to a polymeric mix without nanoparticle inclusion, mechanical behaviour tests demonstrated a considerable improvement in the mechanical capabilities of the nanocomposites, notably at 2%. Mechanical parameters such as tensile strength are 61.36 MPa, flexural strength is 74.25 MPa, and hardness is 83.27 D at 2.5 wt% at 600°C heat treatment conditions. Under 900°C heat treatment conditions, tensile properties of 54.12 MPa at 1 wt. percent, flexural properties of 79.21 MPa at 2 wt. percent, and shore hardness of 81.21 D at 2.5 wt. percent of nanoparticles were measured.

The utilization of renewable raw materials, such as natural fiber composites, can be prioritized in the building industry as it transitions to a bioeconomy. The sustainable product can improve environmental protection; therefore, the present work is stated with the natural fibers of chopped banyan fiber reinforced with sawdust nanocellulose epoxy-based composite fabricated by hand layup process. To identify the mechanical effects of tensile strength, flexural strength, impact strength, and hardness value for five different weight ratios of chopped banyan fibers and sawdust nanofiller materials, the composite weight ratio was made with 60% of matrix phase that was fixed for all five samples and 40% of reinforcement phase in which the fibers and filler percentage can vary for five samples. The results are revealed sample E (50 g of banyan, 25 g of saw dust, 110 g of epoxy, and 185 g of laminate) given a more tensile strength of 39 MPa and a flexural strength of 34 MPa, and sample A was given a high impact energy absorption capacity of 18 Joule compared with other samples of hybrid composite; and also, the SEM morphological was used to identify the surface interaction and failure mode of this composite laminates.

The current research is concerned with the production of an LM25-FE3O4—Gr metal matrix hybrid composites (MMHCs) and the analysis of its dry sliding wear conditions. The hybrid composites were made out of 3 wt% Fe3O4 and 4 wt% Gr particles with a mesh size of 200 meshes and were made using the stir casting method. Wear test on Taguchi's L9 orthogonal arrays employs three process parameters: load, sliding velocity, and distance, each changed for three levels on a pin-on-disc tester position. The wear behavior of hybrid composite was investigated using loads of 20 N, 40 N, and 60 N; velocities of 2 m/s, 4 m/s, and 6 m/s; and distances of 1,000 m, 2,000 m, and 3,000 m. The major parameters were developed utilizing the signal-to-noise ratio by selecting "smaller-is-better" wear rates and COF features. FESEM was used to look at the worn surfaces of the composite specimen in order to determine the wear mechanism. Wear properties are enhanced in materials having aluminium hybrid metal matrix composites. According to the ANOVA table, the load parameter has the greatest impact on wear resistance and coefficient of friction, with maximum load values of 35.64 N and 5.782 N, respectively.
