The tensile and flexural behaviors of pineapple leaf fiber-PP composites as a function of volume fraction were investigated. The tensile modulus and tensile strength of the composites were found to increase with fiber content in accordance with the rule of mixtures. The flexural modulus and stress of the composites increased with the content of fiber but these values were lower than the reported values by other researchers. The lower values for flexural modulus and stress were ascribed to the presence of fiber-fiber interactions, voids, and dispersion level [10]. 

The tensile and flexural behavior of sisal fiber-reinforced polyester composites were investigated as a function of fiber length and fiber content by Sreekumar et al. [101]. Resin transfer molding and compression molding techniques were used for composite making. From the studies, it was found that mechanical properties increased with an increase in fiber loading in both cases [101].

Fabric bending rigidity is a fabric flexural behavior that is important for evaluating the handling of the fabric. The bending rigidity of the untreated cotton and Cu-Ni-P plated fabrics is shown in Table 2. 

Conversely, valve prototypes that have passed 5 and 10 Mio cycles demonstrate looseness of the fabric and higher porosity. An equilibrium should be then found to achieve good mechanical long-lasting flexure behavior, while considering porosity could promote tissue ingrowth and cell infiltration that will lead to bending modulus impairment.
