“…According to composite theory, the overall mechanical properties of a composite are influenced by the mechanical properties of the fiber and matrix elements [ 26 , 27 , 29 ]. It is realized that, if there are very few fibers (ν f.min ) within the matrix, the stress on the composite may be high enough to break the fibers [ 9 ].…”

“…The result is that the composite strength and stiffness fall below those of the matrix. Therefore, there is a critical fiber volume fraction, ( ν f.crit ), threshold below which the fiber compromises the strength and stiffness of the matrix [ 9 , 26 ].…”

“…The experimental values of the three composites fitted differently in all the models tested in this study; namely, Rule of mixtures (RoM), Modified rule of mixtures (MRoM) and Halpin–Tsai (H-T). The H-T model is a semi-empirical model that incorporates the physical properties of the fiber; namely, fiber geometry, packing geometry and loading condition into predicting the composite’s modulus [ 26 , 34 ]. The effect of the physical composite properties is captured by the efficiency factor, ξ , which in this work was taken to be 2.…”

“…Voigt described a rule for predicting the elastic modulus of a composite using the elastic moduli and volume fractions of the reinforcement material and the matrix in the composite [ 9 , 26 , 27 ]. The rule of mixtures (RoM) assumes no void condition of the formed composite and that the constituent materials (reinforcement and matrix) are perfectly bonded together as a unit.…”

“…The Halpin–Tsai model is a semi-empirical model developed by curve fitting of experimental and elasticity-based model data [ 9 , 26 ]. The Halpin–Tsai equation incorporates the parameter, ξ , called the reinforcing factor, which depends on fiber geometry, fiber packing geometry and the loading condition.…”

The Influence of Pineapple Leaf Fiber Orientation and Volume Fraction on Methyl Methacrylate-Based Polymer Matrix for Prosthetic Socket Application

This work reports on the use of low-cost pineapple leaf fiber (PALF) as an alternative reinforcing material to the established, commonly used material for prosthetic socket fabrication which is carbon-fiber-reinforced composite (CFRC) due to the high strength and stiffness of carbon fiber. However, the low range of loads exerted on a typical prosthetic socket (PS) in practice suggests that the use of CFRC may not be appropriate because of the high material stiffness which can be detrimental to socket-limb load transfer. Additionally, the high cost of carbon fiber avails opportunities to look for an alternative material as a reinforcement for composite PS development. PALF/Methyl Methacrylate-based (MMA) composites with 0°, 45° and 90° fiber orientations were made with 5–50 v/v fiber volume fractions. The PALF/MMA composites were subjected to a three-point flexural test to determine the effect of fiber volume fraction and fiber orientation on the flexural properties of the composite. The results showed that 40% v/v PALF/MMA composite with 0° fiber orientation recorded the highest flexural strength (50 MPa) and stiffness (1692 MPa). Considering the average load range exerted on PS, the flexural performance of the novel composite characterized in this work could be suitable for socket-limb load transfer for PS fabrication.

Epoxy structural adhesives have been used extensively in the automotive and aerospace industries to bond assembly parts. Much effort has been devoted to enhancing the mechanical properties of epoxy resin by incorporating fillers. Among a variety of fillers investigated for this purpose, nanocelluloses are regarded as a promising type of emerging green filler material because of their excellent mechanical and physicochemical properties. Indeed, nanocelluloses have been used as a filler for polymer nanocomposites. However, the toughening and reinforcing effects of nanocelluloses on rigid epoxy adhesives have not yet been fully revealed, particularly from the perspective of adhesive bonded joints. Here we report that epoxy adhesive containing cellulose nanocrystal (CNC) aggregates produced using a solvent-free ball milling method achieves drastically improved adhesive strength and fracture toughness compared with that of the reference adhesive without CNCs. The epoxy adhesive containing CNC aggregates exhibited an excellent adhesive strength of 29 MPa and a fracture toughness of 389 J/m2, which were 125% and 378% greater than those of epoxy adhesive without CNCs, respectively.
