“…Thanks to the excellent properties of polypropylene such as high thermal stability, high chemical durability, easy processability and low cost, it is a very versatile material for different applications, not to mention its reusability [1, 2, 3 and 4]. Polypropylene composites are attracting attention among other aspects for their versatility in different applications ranging from medical [5 and 6], industrial [7] and aerospace [8, 9 and 10] as well as in the production of composites with interesting properties such as light weight, low cost, high resistance to elastic deformation, etc. It is known that polypropylene among thermoplastics is one of the most attractive thermoplastics to reinforce and improve its properties making it compatible with most processing techniques [11].…”

Currently, innovation in materials is a highly explored area, due to the requirements to satisfy the industrial needs for intelligent materials that arise mainly with an improvement in physical and mechanical properties. Within the classification of intelligent materials are composites and in this work it is proposed to combine a very versatile and low-cost polymer such as polypropylene and the important mineral called magnetite. By manual injection, three compounds are obtained and evaluated the effect on the thermal and mechanical properties of the polypropylene (PP) composite reinforced with different concentrations of mineral magnetite (5%, 10% and 20%) is evaluated. The three composites obtained (MP5, MP10 and MP20), were characterized by thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA). A favorable effect with MP20 composite is achieved on the thermal properties of polypropylene, managing to extend the thermal stability up to 420°C and improve the storage modulus up to almost 2 GPa.

“…There have been a lot of materials and technologies to reduce the noise. According to the mechanism of noise reduction, it can be classified three categories, sound insulation, 5–8 sound absorption, 9–11 and damping noise reduction 12–14 . Various acoustic materials such as foams, porous particles, hollow microspheres, and fibers exhibited excellent acoustic properties.…”

“…The inorganic particles as fillers have been widely used in sound insulation materials in recent years, 18,20 such as CaCO 3, 21 BaSO 4, 22 carbon nanotubes, 23 carbon black, 19 graphene oxide, 9 mica, 20 glass microspheres, 24 and hollow glass microspheres (HGM) 25 . The HGM are one of the most important inorganic fillers for polymers due to its high rigidity and low density 8 . The main difference between the solid particulate‐filled polymer systems (such as mica or barite) and hollow particulate‐filled polymer systems is the lightweight and the extra consumption of sound wave energy in the hollow microspheres.…”

The high-damping property of polyurethane elastomers and the low density of the hollow glass microspheres (HGM) were used to prepare the sound insulation materials in the present work. The transmission loss (TL) was measured to evaluate the HGM content on the sound insulation properties. The experimental results showed that the addition of HGM improved the hardness and compression modulus of the HGM-filled polyurethane composites, and the loss factor (tan δ) of polyurethane composites were greater than 0.9. The average transmission loss (ATL, from 63 to 6300 Hz) reached 37.32 dB when the content of HGM was 10 wt%. The ATL of the HGM-filled polyurethane composites with 15 wt% HGM in the damping control region and the mass control region were 31.94 and 46.78 dB, respectively. The synergistic effect of the microphase separation, the interfacial effect and the rigidity of polyurethane composites resulted in the improvement on sound insulation property. The polyurethane composite has a great potential application for the field of sound insulation materials.

Porous polymer composites (PPC) have developed rapidly recently, which are widely used in various industrial fields. Viscoelastic damping is an important behavior of porous polymer composites, and it can determine the sound absorption for noise reduction applications. This review has mainly covered the viscoelastic damping and sound absorption of porous polymer composites. Different fabrication approaches of porous polymer composites are gathered. The mechanism of viscoelastic damping behavior is described, and also the sound absorption properties. Followed by the introduction of enhanced sound absorption of viscoelastic damping porous polymer composites, including the incorporation of fillers, microstructures modification, combination with nanofibrous materials, and multilayer configuration, etc. The incorporated fillers can effectively adjust the interfacial area in composites, and obtain desired bonding conditions. Microstructures modification is an effective tool to improve the morphologies of both polymer matrix and fillers, which can be achieved by chemical treatment and surface coating. The combination with lightweight nanofibrous layer can increase the low frequency absorption. The configuration of multilayer composites can improve both acoustical and mechanical properties for engineering applications. It is hoped that this comprehensive review is benefit for the promising development of porous polymer composites in related fields.
