As a new member of the silica-derivative family, modified glass fiber (MGF) has attracted extensive attention because of its excellent properties and potential applications. Surface modification of glass fiber (GF) greatly changes its performance, resulting in a series of changes to its surface structure, wettability, electrical properties, mechanical properties, and stability. This article summarizes the latest research progress in MGF, including the different modification methods, the various properties, and their advanced applications in different fields. Finally, the challenges and possible solutions were provided for future investigations of MGF.

“…The fibers are nonuniformly distributed in the regions around the defects, and there is also a distribution of glass fiber densities. All these features modify fracture behavior of injected pieces changing failure patterns, with crack pathways that follow stress concentrators developed during processing [4].…”

Polypropylene - Polymerization and Characterization of Mechanical and Thermal Properties

View full text Add to dashboard Cite

Polypropylene (PP) is a low-cost plastic commodity, which currently is in a transition zone between massive use and engineering applications due mainly to its limited mechanical properties, such as low tensile and impact resistance. That is the reason why PP is usually modified with additives and particles to improve its mechanical and thermal performance and thus meet the requirements demanded by engineering applications. Besides, PP composites are suitable materials to be processed by a simple, fast, automatic, and massive technique such as injection molding. This makes PP composites attractive for several applications. However, it is important to keep in mind that PP composites' performance depends not only on their intrinsic properties but also on processing conditions. This chapter will summarize the relationship between processing and performance of several PP composite-micro, nano, and hybrid-injected parts with the aim of generating a bridge between technologic knowledge and scientist knowledge.

The extrusion procedure used to manufacture Short Fiber Reinforced Composites (SFRCs) results in significant anisotropy in the components due to the skin-core structure. While there are existing accurate stiffness prediction methods available, there is still a need in engineering for an efficient and cost-effective prediction method. This work proposes an efficient, low-cost and effective stiffness prediction method for skin-core structure using the orientation averaging method and series-parallel model. Initially, the sample underwent analysis using industrial CT and metallographic microscopy to ascertain the fiber characteristics and skin-core dimensions. Furthermore, it is presumed that the skin and core are distinct materials, and their stiffness is determined using the orientation averaging method. Finally, the stiffness of the sample was determined by employing a series-parallel model for analyzing stress-strain transmission, which involved merging the skin and core components. Experimental and finite element results confirm the method's accuracy, boasting a calculation time of 31.36 seconds and a maximum stiffness error below 10%. This method is expected to be applied to automotive, construction, and other engineering fields to meet the demand for fast, cost-efficient, and effective stiffness prediction of SFRCs.
