The construction industry contributes enormously to the high levels of carbon dioxide on the planet. For this reason, the sector has been investing in the development of new products that reduce the environmental impact. This study developed a fibrous polymeric composite using industrial residues of polyethylene terephthalate (PET) fibers for application in civil construction as a cladding element. The thermal and morphological characterization of the fiber was performed using Thermogravimetry (TG) and Scanning Electron Microscopy (SEM). Composites with 1, 3, and 5% PET fibers were obtained. Mechanical, morphological properties, chemical resistance, the effect of ultraviolet radiation and water absorption of the composites were evaluated. The results were compared to parameters established by the Brazilian standard NBR 15.575-3. Fibers had a smooth surface but with small surface defects, diameter between 20 and 30 µm and thermal stability up to 325.44 °C. The addition of 5% PET fibers resulted in an increase of more than 300% in the impact resistance of the composites, but with a reduction in the flexural strength. The mechanical and chemical resistance results met the parameters established by the standard used in the study. The degradation chamber test indicated that PET fibers suffered more from exposure to ultraviolet radiation than the polymeric matrix.

“…have studied effect of PET fibre content on the impact resistance of hybrid PP composites with the coupling agent. They showed good adhesion with coupling agent MAPP increasing the impact resistance of the composites [20]. However, the chemical foaming agent increased the free volume in the structure, according to free volume increase, impact resistance decreased.…”

The automotive industry is among the priority technology areas of our country, and the reduction of vehicle weight and fuel consumption and thus CO2 emissions without compromising safety criteria are among the priority research areas. For this reason, R&D studies on increasing the use of polymer-based materials in the automotive industry are of great importance. In order to produce “high strength and weight reduction parts” in plastic moulding technologies, advanced technologies that focus on cost reduction and efficiency are being implemented rapidly. The chemical foaming process, which provides many advantages such as reducing the consumption of plastic material used, reducing the total moulding cycle time, using less tonnage injection moulding machines, and thus reducing the energy costs, is one of the innovative technologies that have been implemented since a very recent time. In this study, chemical foaming agent were being reinforced at the rate of 1-2-3% in natural fiber-reinforced recycled composite polypropylene raw material. The samples obtained in the injection machine was be moulded in the sizes and shapes in accordance with the standards. Tensile, hardness, impact and three points bending tests would be done. By examining the test results, the mechanical, and morphological properties of natural fiber reinforced polypropylene materials at different chemical agent percentages were examined. With increasing the amount of foaming agent, mechanical properties decreased.

“…Moreover, the natural fibers with slightly different chemical compositions and irregularities in their shape when used in different combinations as reinforcement in polymer composites help to achieve desired functional properties in polymer composites. 8 The exceptional features of plant-based natural fibers over synthetic fibers such as abundant availability, enhanced acoustic insulation, good thermal stability, low cost and lightweight have been further influential for researchers to suggest natural fibers as an alternative for replacement over synthetic fibers in composite industries. 9,10 The literature already reports the use of natural fibers in domestic appliances and automobile interiors for non-structural applications.…”

This work presents the comprehensive characterization of alkali treated areca fruit husk fiber (AAFHF) an industrial agro-waste reinforced unsaturated polyester resin (UPR) matrix hybrid composite with silicon carbide (SiC) nanoparticles as filler material. Hybrid composite plates were fabricated with 40 wt% of AAFHF and diverse wt% of SiC nanoparticles ranging from 1 to 4 wt% in steps of 1 wt%. The effect of wt% of SiC nanoparticles in hybrid composite over mechanical, morphological, wear, thermal and water absorption characteristics was investigated. The findings help to conclude that a hybrid composite plate with 3 wt% filler content excels in overall properties. Meanwhile, the accumulation and meager scattering of SiC nanoparticles in composite deteriorated the functional characteristics when the wt% of filler content enhanced to 4 wt%. Also, the failure pattern and interaction between AAFHF, SiC nanoparticle and UPR were understood from the images obtained using Scanning Electron Microscopy (SEM). In addition, the availability of functional groups, crystallite size and crystallinity index was obtained from Fourier transform infrared (FTIR) spectrum and X-ray diffraction (XRD) analysis for the optimum filler content respectively. Moreover, the achieved results suggest the suitability of the developed composite for marine and lightweight applications.
