“…When comparing these results with other studies, it was observed that there is concordance such as those reported by Bruscato et al (2019), who obtained data between 300 and 350 kg/m 3 , other authors report densities between 57 and 209 kg/m 3 (Holt et al, 2012;López Nava et al, 2016) Exhibit 7A and B shows the trend of the fracture values of the material at maximum stress that varies for each replicate and treatment, evidencing that the matrix does not have sufficient strength. This behavior is due to the arrangement of the fibers within the composite material (Chandramohan, 2020) as well as to the low internal and heterogeneous growth of the mycelium due to the possible lack of air and available moisture between the fibers, making the material nonuniform and brittle. It is worth noting that at T50 a brittle behavior is evidence that does not prevent the material from breaking, some studies have reported that the thickness of the mushroom skin influences this mechanical property (Appels et al, 2019).…”

In this work, three lignocellulosic residues, coconut fiber, sugarcane bagasse, and fique bagasse, were used as a carbon source for fungal colonization had been proposed to form a composite material. The lignocellulosic residues presented a high percentage of carbon. The lignocellulosic residues had been conditioned and characterized morphologically. The particle sizes chosen were 16 and 50 sieves. The mycelial growth kinetics of the fungi had been evaluated in the residues, where a higher growth rate was observed in the medium enriched with coconut fiber and lower in those containing bagasse. When studying these intrinsic factors, it was observed that an inadequate carbon-nitrogen (C/N) ratio affected mycelial growth. This method of obtaining biomaterials is a promising alternative to lignocellulosic substrates as substrates for fungi with delignification capacity.

“…The property of pure epoxy with fibre is poor, exhibiting low stiffness and decreased mechanical properties. The laminate's compressive and flexural strength can be dominant by adding additives or fillers to the resin at varying percentages [1]. CFRP results in a very elevated strength-to-weight ratio and makes it exceedingly rigid.…”

The mechanical and vibrational isolation properties of reinforced carbon fibre composites, such as carbon fibre [0]7s/epoxy, carbon fibre [0]6s/Graphene nanopowder/epoxy, and carbon fibre [0]4s/epoxy/Al 6061, are investigated in this research. Ultrasonic stirring was employed in a carbon fiber/graphene-nano powder laminate to reinforce 0.5 weight percent graphene nanoparticles with the resin. The effect of nano-fillers and metal laminate in the carbon fiber composite specimen was analysed by considering glass transition temperature, flexural modulus, and natural frequency. The results show that the Carbon Fiber Reinforced Polymer (CFRP) with graphene shows a 16.9% and 57.5% increment in flexural strength compared to CFRP and CFRP with Al6061 alloy. In contrast, in the DMA test, the glass transition temperature and other parameters show the least difference, whereas the loss modulus is 34.3% and 67% high for CFRP compared to CFRP/graphene and CFRP/Al6061 samples. Furthermore, using graphene nanopowder and aluminium plates reduces the carbon epoxy laminate's inherent frequency.

“…Composite materials are a mixture of two or more distinct materials constituting matrix and reinforcement. In comparison with many metals and non-metals, mechanical properties such as combination of strength, stiffness, toughness, and corrosion resistance are significantly found in composites (Chandramohan, 2020;Singh et al, 2013;Tsao & Chiu, 2011). Fiber-reinforced polymer composites involving fiber phase provide strength to the composite, whereas the reinforcement phase absorbs energy resulting in increase in toughness.…”

Carbon fiber-reinforced composite laminates are progressively appealing for several applications in various manufacturing sectors such as aeronautical and automobile, because of their amazingly predominant mechanical properties. This has subsequently led to an increase in research of various machinability techniques emphasizing on both conventional and non-conventional methods. Typically, conventional drilling is one of the most significant machining processes for most kinds of fiber composite laminates. The most unsolicited damage termed as delamination during drilling has recently become one of the most influential research subjects as numerous engineers in manufacturing sector have been trying to prevent this problem over decades. This review paper briefly discusses about the incorporation of different types of fillers in carbon fiber-reinforced composites. The paper also summarizes the steady progress in drilling-induced delamination of carbon fiber laminates. It covers the delamination formation mechanism, delamination suppression strategies, and the optimization of various drilling parameters to reduce the delamination damage. The present article provides researchers an opportunity to deepen their knowledge on specific aspects by exploring different methods for reducing delamination in CFRP composites.
