“…The results of these tests shed light on the specific mechanical behavior and performance characteristics of KRC Bilal Zahid et al introduced a vacuum bag method for fabricating Kevlar-based composites, enhancing mechanical properties through proper compaction of Kevlar fibers within the matrix material [8]. Herbert et al focused on Kevlar-49 reinforced composites with thermoplastic and thermosetting matrices, utilizing theoretical models to predict mechanical properties and assessing their accuracy through experimental comparison [9]. This analysis elucidates the interplay between material composition, processing parameters, and mechanical attributes.…”

In recent years, synthetic fiber reinforced composites have attracted more and more attention. The advantages of these materials compared to other traditional metal materials are reflected in their lighter weight, more unique flexibility, and superior mechanical properties. Because of this, these synthetic fiber composites are increasingly used in industry, the military, and other advanced technologies. Among them, Kevlar fiber composites have unique properties. Compared with other synthetic fibers, it has lower fiber elongation and higher tensile strength and modulus. Not only that, but the Kevlar composite also has better thermal properties and impact resistance. This article will first introduce the properties of Kevlar fiber, and then introduce different kinds of Kevlar composite materials. These include MS-Kevlar, SSG@Kevlar, Kevlar-Reinforced composites, and Kevlar aerogels. Because these composites have many different properties, they can have corresponding products in many different fields. The knowledge of existing materials helps us think about more applications for these new composites.

To enhance the utilization of solid waste in cement kiln co-processing, this study analyzed the multifaceted synergy of pyrolysis and mineralization processes of iron-rich sludge (SS) and waste incineration fly ash (FA) at optimal blending ratios. Based on the physicochemical properties of SS and co-pyrolysis experiments, it was found that Fe acted as a positive catalyst in pyrolysis between 700 and 1000 °C, while the endogenous polymerization effect of Fe(III) mineral groups dominated above 800 °C. Additionally, the study investigated the solidification and migration of heavy metals and the transformation of harmful elements (S, Cl, and P). Results indicated that the best mixture ratios for SS and FA were 6:4 and 9:1, respectively, and synergistic pyrolysis and mineral co-curing effects were observed in the pyrolysis temperature range of 50–1000 °C. The synergy between SS and FA allowed for the decomposition and solidification of harmful organic components and heavy metals, reducing environmental risks. Furthermore, in actual production, by mixing 100 tons of SS and FA with Portland cement with a daily output of 2500 tons, the compressive strength during early hydration stages can reach 34.52 MPa on the third day, exceeding the highest performance of Portland cement (62.5R) strength index specified in the standard.
