“…However, jute/PP composites display linear behavior before entering the plastic region. Then the jute/PP composites break abruptly [32,33]. It is clearly shown that the tensile strength and tensile modulus of carpet composites were lower than that of jute/PP composites.…”

Without additional matrix or reinforcement, compression molded composites from waste polypropylene (PP) carpets/nylon (PA) carpets or PP carpets/polyester (PET) carpets have higher mechanical properties and sound absorption than traditional jute/PP composites. Large amount of carpets have been discarded every year, leading to waste of petro-based materials and serious environmental pollution. Fabrication of composites from discarded carpets via compression molding could save petroleum resources and alleviate environmental pressure. In this research, the compression molded composites from waste PP/PA carpets or PP/PET carpets showed good mechanical properties, sound absorption and water stability. Compared to the jute/PP composites, nylon 6,6 (PA66)/PP carpet composites had 37% and 9% higher flexural strength and impact resistance, as well as 45% and 10% higher sound absorption and water stability, indicating their potential for transportation and construction industries.

“…This confirms that this material is more damaged when the core is subjected to shear loadings. Then, considering that the W€ ohler curves can be fitted by an expression such as the one presented in equation (15), the value j1=Bj was used to compare the fatigue properties of the Flax/Elium/Balsa beams tested with a span length of 250 mm to those of non-biobased beams tested in the same experimental conditions [42,43]. The geometrical and material properties of the sandwich beams considered are presented in Table 5.…”

“…They achieved good mechanical properties and proved that the manufacturing of this material had a lower environmental impact than sandwiches with GFRP skins. Karaduman et al [15] also studied the flexural properties of a sandwich beam made up of lute/ polypropylene (PP) skins and a balsa wood core. The authors emphasised the higher mechanical stiffness and strength of the balsa core compared to polyethylene terephthalate (PET) foam or PP honeycomb cores.…”

The material studied is made up of thermoplastic skins reinforced by flax fibres and applied to a balsa core. It is produced by a single-step liquid resin infusion process. First, the skin-core interfacial properties were measured and compared with those of the existing materials. Then, several quasi-static and dynamic analyses were performed to study the flexural behaviour of sandwich beams. The elastic and ultimate properties of the skins and core were deduced from these flexural tests. In addition, a failure mode map was developed based on the existing theories to explain the failure modes observed under different boundary conditions. The influence of the statistical spread of the core's mechanical properties on the failure of sandwich beams was considered. Moreover, fatigue analyses were conducted to determine the fatigue resistance of this bio-based structure. Its behaviour was compared with that of the previously tested non-bio-based sandwich beams.Finally, the fatigue loss factor evolution of this structure under several loading ratios was measured and discussed. This study aims to determine some of the main mechanical properties of this material to see whether or not it might be suitable for industrial applications currently using glass fibre reinforced polymer/foam cored sandwich structures.

“…Moreover, the polar bond tends to hinder the interaction of this type of fiber with apolar matrices, interfering in the fiber / matrix interfacial adhesion. Thus, for a good interface to be formed, a pretreatment must be done with coupling agents or compatibilizers on the surfaces of the fibers 28 . As in this work, jute fibers were used as received, it is probable that the lack of adhesion represented by Figure 13 (B) is related to the absence of a pretreatment on the surface of jute fibers.…”

The commingled technology is a promising technique for the manufacture of composites reinforced with natural fibers. This study presents the development, processing and basic characterization of a long fiber Jute/Polypropylene (Jute/PP) commingled composite. The Jute/PP fabric was produced in a handloom and the composite was consolidated by compression molding. The PP matrix was chemically and thermally characterized to certify its chemical composition and define its melting and crystallization temperatures. The degradation behavior of jute fibers was also studied by Friedman's kinetic isoconversional model using thermogravimetric analyses (TGA). The mechanical properties of jute reinforcement and Jute/PP composite were characterized by tensile strength tests and by fractographic study of the fracture surfaces. Its tensile strength (44.62±6.02 MPa) and elasticity modulus (7.10±2.34 GPa) are approximate to the ones obtained by other processing techniques, suggesting that the developed commingled process can work as a low cost and practical alternative methodology for manufacturing of more sustainable composites in industries.
