“…Among the coupling agents, silanes have a hydrophilic structure with different groups attached to the silicon atom where one end interacts with the matrix and the other one interacts with the hydrophilic fiber (e.g., BFs) [ 13 , 14 ]. The MA polar groups also form covalent and hydrogen bonds with the surface of the BFs, which improve the BF-matrix adhesion [ 7 , 12 ].…”

“…The flexural strength (σ f ), flexural modulus (E f ), and strain-to-failure (ε f ) of each strip were evaluated from the measured load-displacement data as follows [ 14 ]:

where L , b , and h are the length, width, and depth of the specimen, respectively. P max is the maximum recorded load, m is the slope of the tangent to the initial straight portion of the load–deflection curve, and D is the maximum deflection before the strip failure.…”

Low-density polyethylene is the most common polymer for manufacturing containers, bottles, tubes, plastic bags, computer components and so on. There is an urgent need to find solutions for its recycling and reintegration in high volume production components such as non-structural auto applications. The reinforcement of recycled low-density polyethylene with natural fibers represents a solution for the re-use of the recycled low-density polyethylene. However, there is a lack of understanding of how the natural fibers influence the behavior of the bare low-density polyethylene, and furthermore, how the interface between the fibers and the matrix can be controlled in composite to obtain the designed toughness, strength, stiffness and damping. In this sense, the study presents an in-depth analysis of the behavior of three coupling agents used in the chemically functionalized bamboo fibers interface for reinforcing low-density polyethylene composites. Through mechanical tests, the mechanical properties are determined and compared and finally, a correlation between the viscous behavior of the resulted composites and the toughening mechanism is proposed. The conclusion of the study enables a flexible design of polymer composite components fabricated of recycled and non-recycled low-density polyethylene and natural fibers.

“…Some of the properties of these composite materials such as its mechanical strength (tensile strength, flexural strength, impact strength), fracture toughness, etc. have been improved through the years so much that they could be compared with the conventional materials like steel (Kerni et al, 2020;Wang et al, 2020).…”

“…The durability, shape, environmental compatibility, and appearance (Omrani et al, 2016). Some wellknown sources of natural fibers which have been explored for application in engineering, industrial and consumer goods applications are banana, jute, coir, sisal, and kenaf (Wang et al, 2020). Sources like pineapple leaves have hardly been explored due to the set back of non-adhesiveness of the fibers with most polymer matrix materials (which is poor interfacial interaction between fiber and matrix) even though there have been attempts to surmount this setback by the surface modification of the fibers.…”

In this study, a Pineapple Leaf fiber (PALF)/Glass fiber Epoxy hybrid composite PxGyEz (with x, y, and z representing the volume fraction of pineapple leaf fiber (P), volume fraction of glass fiber (G) and fiber length respectively in Epoxy (E) matrix) was developed and its tensile properties modelled and optimized with regards to the variable parameters of x, y, and z respectively. For the quality characteristics (high tensile strength) investigated, the Minitab®19 software was used to analyze the Taguchi robust experiment design technique on the higher the better basis. The optimum combination of the control factors was found at x=10%, y=20% and z = 15mm. The optimized composite P10G20E15 possessed a tensile strength of 95.3144MPa which was only a 5.9% deviation from the predicted optimum tensile strength. Analysis of variance showed that the glass fiber had the highest contribution of 50.64% to the tensile strength of PxGyEz, PALF 15.53% and fiber length 28.84%. SEM Images of the PALF, glass fiber and fractured surface of the optimized material P10G20E15 revealed the surface structure which explained their different contribution to the tensile strength of the materials. An equation for the prediction of the tensile properties of PxGyEz was derived from the regression model.

With the continuous need for sustainable, environmentally friendly, and low-cost systems, processes, and materials, natural fibers have been a major topic of discussion in the materials science community as it has increasingly found acceptance in material development as an alternative to synthetic fibers due to environmental concerns. Although many studies have been carried out in this regard, the optimal flexural performance of pineapple leaf fiber/synthetic fiber hybrid reinforced composite has not been studied even with its promising application in aviation, health, and fitness, marine, etc. In this study, a Pineapple Leaf fiber (PALF)/Glass fiber Epoxy hybrid composite PxGyEz (with x, y, and z representing the volume fraction of pineapple leaf fiber, the volume fraction of glass fiber, and fiber length respectively) was developed and its flexural properties optimized and modeled with regards to the variable manufacturing parameters of x, y, and z respectively. For the quality characteristics (flexural strength) investigated, the Minitab®19 software was used to analyze the Taguchi robust experiment design technique on a higher the better basis. The optimum combination of the control factors was found at x = 20%, y = 20%, and z = 25mm. The optimized composite P20G20E25 possessed a flexural strength of 144.4994MPa which was only a 7.17% deviation from the predicted optimum flexural strength. Analysis of variance showed that the PALF had the highest contribution of 23.97% to the flexural strength of the PxGyEz, glass fiber 7.13%, and fiber length 12.79%. SEM Images of the PALF, glass fiber, and the fractured surface of the optimized material P20G20E25 revealed the surface structure which explained their different contribution to the flexural strength of the materials. An equation for the prediction of the flexural properties of PxGyEz was derived from the regression model and it had an approximately 77.57% agreement with experimentation.
