“…The three‐point‐bending flexural strength values of the obtained composites range from 60 to 96 MPa, comparable with those obtained from reference literature regarding PVC–wood composites (53–87 MPa), PVC–calcium carbonate (50–80 MPa), and even layered polypropylene–wood composites (70–120 MPa) . The increased interfacial adhesion between components, promoted by wood addition determines a 26% increase in flexural strength of the P2 composite and a 34% increase in the case of P3, by comparing with P0.…”

“…Moreover, the addition of certain inorganic fillers, such as calcium carbonate, metal particles, montmorillonite, mica, and so forth leads to an efficient thermal stabilization of the polymer, while providing composite materials with higher wear resistance, stiffness and hardness values at lower material costs than in the case of using PVC alone. An improvement in the thermal‐, sound‐insulating, and mechanical properties of the material (flexural strength, impact resistance) was also achieved through mixing PVC with “green” natural cellulose fibers and wood, providing higher performance/weight ratios in comparison with inorganic fillers …”

In this article, poly(vinyl chloride) (PVC) sandwich-structured hybrid composites with amorphous calcium carbonate and wood-filled cores were obtained by compression molding. It has been determined that wood addition up to a weight ratio of 33% reported to the total filler amount is beneficial in improving both the inter-filler and filler-matrix interfacial adhesion, which alongside with the promoting of the amorphous PVC matrix crystallization is responsible for an increase up to 34% in the flexural strength of the composites, compared to unfilled PVC. The hybrid filled composites present up to 35% lower friction coefficients and up to 20% higher Brinell hardness values than the composites filled with calcium carbonate alone. Subsequently, wood addition determines an increase in the oxidation onset temperature for PVC and an increase with up to 20% in the sound and thermal-insulative properties of the composites, compared to unfilled PVC. The dominating dispersive part of the composites surface energy aids in improving the mass and dimensional stability of the assembly to both water and dilute hydrochloric acid aqueous solutions.

“…Natural fiber/polymer composites produced from natural fibers embedded in thermoplastic resins [e.g., polypropylene (PP), polyethylene (PE), poly(vinyl chloride), polystyrene], are crucial one of several various types of natural fiber‐reinforced composites . They have tremendous potentials as an innovative alternative engineering material for residential and industrial applications like flooring, siding, decking, landscaping, fencing, and transportation.…”

In order to develop excellent comprehensive mechanical strength and stability in high-density polyethylene (HDPE)/wood fiber (WF) composites, polyamide 6 (PA 6), and WF modified by environmental-friendly high temperature vapor (WF-HTV) were utilized to reinforce the compound system. The properties relating to interfacial compatibility in HDPE/WF-HTV composites were characterized and evaluated by electron universal mechanical instrument, water absorption testing, thermogravimetry, scanning electron microscope, Fourier transfer infrared spectroscopy, and differential scanning calorimetry. The results reveal that this novel compounding system can engender a synergistic effect for interfacial interactions among PA 6, HDPE, and WF-HTV only when the ratio of HDPE to PA 6 is at an optimum level (HDPE:PA 6 = 6:4). The maximum values for flexural strength, modulus, tensile strength, and impact strength can be increased by 82.05, 64.08, 93.47, and 120.45%, respectively, compared with those of HDPE/WF-HTV composites. Additionally, maximum decomposition temperatures for the first and second thermal degradation stages can be increased by 7.17and 8.99 C, respectively. Water absorption can be effectively controlled at a relatively low level (approximately 1.50%).

“…Adicionalmente, esta propiedad se puede evaluar teniendo en cuenta la temperatura del medio en el cual se encuentra el material compuesto. Se han reportado grandes disminuciones en la resistencia a la flexión (59.3%, de 32.3 a 13.1 MPa) para un rango de temperatura entre 25 y 70°C [30]. El módulo de flexión o módulo de elasticidad en ensayos de flexión, mide la resistencia de un material al ser sometido a fuerzas que incidan en su deformación o curvatura [31].…”

Resumen-Este trabajo presenta una revisión general del aprovechamiento de residuos plásticos y lignocelulósicos para la producción de Materiales Compuestos Madero Plásticos (MCMP). Los compuestos madero plásticos, o como son conocidos mundialmente, Wood Plastic Composites (WPC), son propuestos como una solución a la creciente generación de residuos. En la obtención de estos materiales, se han evaluado diferentes mezclas de matrices poliméricas (plásticos) y refuerzos vegetales (residuos lignocelulósicos), empleando tres tipos de procesos, principalmente: extrusión, inyección y moldeo por compresión. Se encontró que los cambios en las propiedades mecánicas del producto fi nal dependen del tipo de materia prima, tamaño de partícula y proporción de fi bra empleado, así como la adición de agentes ligantes. Del mismo modo, se reportan variaciones en la capacidad de absorción de agua, densifi cación y estabilidad térmica del compuesto fi nal al aumentar la cantidad de fi bra en la mezcla.
