“…The characterization of mechanical properties of NFC plays a crucial role in determining their actual applicability in substitution to traditional composite materials . Models for the prediction of mechanical properties such as the ultimate tensile strength (UTS), the modulus of elasticity (MOE), or the strain of NFC are necessary to enable the adoption of these materials in engineering design …”

The adoption of natural‐based fibers in place of inorganic reinforcements is an effective approach to reduce the environmental and economic impact of composite materials. In particular, hemp is an attractive solution due to its mechanical, physical, and growing properties. The present article deals with the manufacturing of thermoset hemp‐reinforced composite materials. In particular, the investigation moves into the production by resin transfer molding and by resin powder molding with the use of epoxy polymeric material. To describe the effects of the technological cycle onto the characteristic of realized products, different manufacturing parameters have been combined during the braiding of reinforcement and the polymerization of the final composite. Computed tomography, microscopical analysis, and tensile tests have been used to observe the main effects of the manufacturing process and mechanical properties of the materials. Furthermore, elastic moduli of the materials have been estimated by means of modified rule of mixture and Halpin‐Tsai models in order to verify their effectiveness in forecasting stiffness of the hemp‐reinforced composites in the early design phase. The article extends the existing knowledge base on hemp‐reinforced thermoset composites manufactured with different processes. Results also illustrate relations existing between error introduced by calculation models and the intrinsic variability in mechanical properties.

“…However, PA11 has poor wear resistance [4], which limits its widespread applications in many fields including the offshore and automotive industry for which the wear properties are the most important tribological characteristics [5][6][7]. According to the literature [4,[8][9][10][11][12][13][14], one of the most efficient methods to improve the tribological properties of polyamides consists in incorporating a small amount of nanofillers into the polymer matrix. This often leads to an improvement in the tribological properties of the nanocomposite materials due probably to the high contact surface area of the nanoparticles, which develop more interactions with the polymer matrix [15].…”

AbstractThis article reports some morphological, tribological, and mechanical data on polyamide-11(PA11)/halloysite nanotube (HNT) nanocomposites prepared by melt-compounding. HNTs extracted from the Djebel Debbagh deposit in Algeria were incorporated into the polymer at 1, 3, and 5 wt%. For comparison, commercial HNTs were also used under the same processing conditions. Scanning electron microscopy showed that both HNTs were homogeneously dispersed in the PA11 matrix, despite the presence of few aggregates, in particular at higher filler contents. The tribological properties were significantly improved, resulting in a decrease in the friction coefficient and the wear rate characteristics due to the lubricating effect of HNTs. This is consistent with optical profilometry data, which evidenced the impact of both types of HNTs on the surface topography of the nanocomposite samples, in which the main wear process was plastic deformation. Furthermore, Young’s modulus and tensile strength were observed to increase with the filler content, but to the detriment of elongation at break and impact strength. Regarding the whole data, the raw Algerian halloysite led to interesting results in PA11 nanocomposites, thus revealing its potential in polymer engineering nanotechnology.

“…It is a natural reaction of a substance that may either be mechanical or chemical [56]. One of the principal causes of material failure and damage to equipment is identified as friction and wear [57][58][59]. Manoj Panchal et al [60] reported tribological properties of boiled and unboiled eggshell particulates epoxy composites that are exposed to saline, mineral, subzero, and kerosene environments.…”

Hybrid polymer composites are more attractive because of their light in weight, more robust and rigid (in the direction of fiber) than traditional or unreinforced polymers with the added advantage of having their design and form adapted to suit the specifications of a particular application by the combination of the right choice of the materials. Reinforcement in a polymer hybrid composite can be fiber, filler, or fiber& filler together. Integrating reinforcement into polymers can lead to significant growth in the wear characteristics and mechanical properties of the polymer. Nevertheless, in applications wherever interaction by the liquid medium is inevitable, the mechanical properties and wear characteristics of hybrid polymer composites undergo degradation, which is a generally seen phenomenon since liquid medium acts as a plasticizer. This study aims to provide detailed information on the mechanical and tribological effects of hybrid polymer composites. More emphasis is given towards degradation of mechanical properties such as tensile strength, bending strength, and degradation of wear characteristics like erosion wear rate, and respective failure characteristics were analyzed under different environments such as water, kerosene, saline, sub-zero conditions.
