“…Based on the tests, it is seen that the specimen with epoxy resin HSC 7600 and glass fibers exhibited higher values for Young's modulus. On taking the average, the composite with HSC 7600 had a value of 6.28 GPa, which is close to the desired value of 6.65 GPa [18]. The sample after testing on the UTM is shown in Figure 2.…”

“…Based on available data of the mechanical properties of willow wood, a fiber-reinforced epoxy resin composite is taken as a prospective choice. Adekomaya and Adama [18] studied the effect of loading and orientation of fibers on the tensile and impact strength. They used a glass fiber reinforced epoxy resin ED-20 that had properties similar to our requirements.…”

The sports industry predominantly makes use of wood for manufacturing equipment such as cricket bats. However, the equipment has to be replaced often as it gets worn out and damaged. This has led to increased wood consumption, which is rapidly becoming scarce, contributing to environmental issues. The objective of this work is to provide a protective composite layer on the face of the bat to enhance its life without affecting its performance. This work also aims to find a solution to reduce the wood consumption in the cricket industry in the form of a protective composite layer. The layers on the bats are prepared using two different resins, namely HSC 7600 and General Purpose resin with 400 GSM glass fibers as the reinforcement. The specimens are prepared using the hand-layup process and then cured in the oven. The composite materials are then subjected to tensile tests and impact tests. Properties such as Young’s modulus and impact stress are obtained. When compared with willow wood, the specimens prepared using HSC 7600 exhibit similar properties and can be used in practical applications. The layer once applied on the bat, is subsequently tested under traditional match-like conditions wherein more than 2000 shots are played with a standard leather ball. Regular willow bats are tested similarly, and cracks begin to appear after approximately 1700 shots. Testing of the bats that are reinforced with the composite layer shows that the layer is intact with negligible damages. It is concluded that this material is more resistant to the impact of the ball and also does not provide the batsman with an unfair advantage. With proper implementation, the application of such a layer is a promising solution to be put to use in the cricket industry that tackles the challenge of excess wood consumption.

“…In addition to this work, the influence of the reinforcing fiber orientation was studied. As shown in experiments, changes in the fiber orientation angle can decrease the strength of the material in specific test directions that significantly improved the mechanical properties of oriented reinforcement composite materials [13].…”

The use of environmentally friendly materials has recently been promoted due to increased awareness of environmental issues. To offer a better world for future generations, we must decide what we will utilize and serve today. When resources and products reach the end of their useful lives, resource preservation and degradation become issues. Biodegradable products manufactured from renewable resources address these issues. This research aims to develop a biodegradable resource of false banana (ʾənäsätə) fiber as reinforcement with polyester resin composite material manufactured by hand layup method at room temperature. The mechanical and physical properties of the produced sample were investigated. include tensile, flexural, impact strength, and water absorption. The fiber surface was treated with NaOH alkaline in distilled water solution. In composites, the fiber orientations were 0o, 90o, 45o/-45o, 0o/90o, and chopped, at 40% fiber volume fraction. The sample's production process was performed successfully. A chopped sample is an easier manufacturing process relative to the other. As the result, 0o fiber direction scored the highest tensile strength, which is 181.41MPa. In the flexural and impact strength test, a 90o oriented fiber was observed with the highest value, which is 81.43 MPa and 9.75 joules, respectively. The samples were immersed in distilled water until saturated. The highest percentage of water absorption was 45o/-45o oriented fiber. Many researchers have recently shown interest in natural fiber composites material for aerospace and automotive applications, such as aircraft radomes and interior cabin components, as well as remarks on natural fiber composites' future trends and problems. This article provides readers with a positive perspective and piques industry players' interest in the potential of using natural fiber composites in aerospace applications to improve current aerospace material performance, particularly in terms of lightweight and environmental sustainability.

“…They found the postponement of thermo-oxidative decomposition by enhancing the GF volume in the composite. Adekomaya et al 20 used a passive infrared thermograph approach to describe the damage and thermomechanical characteristics of GFRC materials exposed to static tensile force. They used cross-ply GFRP laminates made from 0/90° lay-ups created from single-direction E-type GF sheets.…”

Hybrid composite materials are a form of material that incorporates more than one type of reinforcement into a matrix to attain enhanced qualities. This usually includes the use of nanoparticle fillers in classic advanced composites with fiber reinforcements such as carbon or glass. In the current investigation, the impact of carbon nanopowder filler on the wear and thermal performance of the chopped strand mat E-glass fiber-reinforced epoxy composite (GFREC) were analyzed. Multiwall carbon nanotube (MWCNT) fillers were used; they react with the resin system to contribute a significant improvement of properties in the polymer cross-linking web. The experiments were carried out employing the central composite method of design of experiment (DOE). A polynomial mathematical model was created using response surface methodology (RSM). To forecast the wear rate of composites, four machine learning (ML) regression models were built. The study’s findings indicate that the addition of carbon nanopowder has a substantial impact on the wear behavior of composites. This is mostly owing to the homogeneity created by the carbon nanofillers in uniformly dispersing the reinforcements in the matrix phase. Results revealed that a load of 1.005 kg, a sliding velocity of 1.499 m/s, a sliding distance of 150 m, and 15 wt % of filler were found to be the optimal parameters for the efficient reduction of specific wear rate. Composites with 10 and 20% carbon contents exhibit lower thermal expansion coefficients than plain composites. These composites’ coefficients of thermal expansion fell by 45 and 9%, respectively. If the carbon proportion increases beyond 20%, so will the thermal coefficient of expansion.
