The industrial process plays a vital role in the manufacturing of various products, but it also faces challenges such as that arising from waste generation. Transforming these byproducts into value-added resources is a growing goal to promote economic and environmental sustainability. In this context, this study aims to evaluate how the incorporation of red mud waste influences the tensile strength of polyester matrix composites. Five formulations were prepared, ranging from 0 to 40 wt.% red mud waste, with a particle size of 50-100 mesh. The density of the red mud waste and the composites were calculated. The composites were manufactured by the compression molding method, using a stainless-steel mold with dimensions of 300 x 160 x 2.5 mm. Through tensile tests, it was possible to identify that 10, 20, 30 and 40 wt.% red mud waste/ polyester composites exhibit higher tensile strength, exceeding by 42.75%, 53.83%, 31.76% and 22.54% the tensile strength of the neat polyester, respectively. The mechanical properties obtained were treated by analysis of variance (ANOVA) and Tukey test. Furthermore, a fractographic analysis was carried out using scanning electron microscopy (SEM) to analyze in detail the fracture surfaces of the tested samples and understand the failure mechanisms of each composite material.

“…Kevlar composite can be found not only in the military but also in the aerospace industry as an engine protection layer. Graphene is mixed with Phase Change Materials (PCM) and recycled plastics as building materials with better indoor thermal conditioning than conventional materials (Acuña-Pizano et al, 2022). PCM composite is also used as a heat absorber in EV to protect the battery pack from overheating.…”

One of the key components of Electric Vehicles is the battery pack compartment casing, which needs to be both as light and as strong as possible to cover maximum mileage while withstand vibrations and other mechanical abuse. A layer of thermal protection is also placed to the case because a typical Lithium battery used for an EV is very sensitive to temperature. In this study, a heat-absorbing lightweight composite for the battery pack compartment casing of an electric vehicle is physically constructed and put to the test to determine its mechanical characteristics. The latent ability of organic phase change materials to absorb heat without experiencing thermal rise led to their use as fillers for the resin composite. Depending on what type and how much phase change materials are utilized, the tensile evaluation reveals that the average strength is noticeably compromised. The composite preparation techniques, including the use of carbon fiber as reinforcement material, are also briefly covered in this paper.

This systematic review study adopted the PRISMA methodology to investigate recent research on wood-plastic composites (WPC) utilizing post-consumer plastics in the construction industry. Initially, 3111 articles were selected from academic databases using keywords such as “wood and plastic composites”, “WPC”, “polymer”, “recycled”, “waste”, “construction”, and “sustainability.” After stringent exclusion criteria, 15 relevant studies on plastic waste composites were identified. These studies often employ post-consumer plastics like polypropylene and high-density polyethylene, along with plant-based fillers, aiming to enhance mechanical properties and reduce reliance on virgin materials. Analysis of these studies revealed that the optimal plastic composition in the composites ranged from 40% to 45% wood and from 50% to 60% plastic, with the extrusion process being the most employed for shaping. Specific factors, such as the use of compatibilizers and the particle size of raw materials, were identified as significant influencers on composite strength. These materials exhibited high thermal stability, rendering them suitable for construction applications exposed to high temperatures. The diversity of plastic waste explored in the studies underscores the potential to tailor thermal properties to specific application demands. These composites facilitate closed-loop plastic recycling, enabling their reintegration into the production chain and offering opportunities for lightweight, durable, and high-performance products in the construction industry. However, beyond the factors examined in the studies, a meticulous assessment of the fire resistance, weather resistance, ultraviolet resistance, moisture absorption, dimensional stability, degradation, long-term durability, impact strength, recyclability, and cost-effectiveness of the material is crucial. Thoughtful consideration of these factors is essential to achieving a comprehensive understanding of the potential and limitations of recycled plastic composites in promoting energy efficiency and sustainability in the construction industry.
