Optimization of Injection Molding Process for High-Strength and Lightweight Back Rest of Firefighters Using Carbon Fiber Composites of Long Fiber Thermoplastic with Flame Retardants
Published on 2025-02-28 by Kyoung-Jae Min, Joon-Hyuk Song, Hyun Tak, Bhum-Keun Song @MDPI
Abstract: This study focuses on reducing the weight of oxygen respirators in firefighters’ personal protective equipment (PPE), which currently accounts for about 56% of the total weight. The heavy PPE, weighing between 20 and 25 kg, restricts movement and can lead to musculoskeletal injuries. To address this, the study investigates using a carbon fiber-reinforced composite for the backrest of the oxygen respirator to reduce weight while maintaining strength. The backrest was fabricated usin[...]
Our summary: Study focuses on optimizing injection molding process for lightweight backrest of firefighters using carbon fiber composites with flame retardants, reducing weight of PPE by 12.8% while maintaining strength, improving firefighter safety.

The Role of Fluids and Nanofluids—A Comprehensive Review
Published on 2025-02-20 by Sandra Sorte, Alexandre Salgado, Andr� Ferreira Monteiro, Diogo Ventura, Nelson Martins, M�nica S. A. Oliveira @MDPI
Abstract: The ongoing pursuit of enhanced efficiency and sustainability in power transformer cooling systems has spurred extensive research into the properties and performance of insulating fluids. This review explores the evolution of transformer cooling technologies, focusing on traditional mineral oils and the emerging roles of alternative fluids, such as natural and synthetic esters, and nanofluids. Mineral oils, though widely used, degrade over time, leading to a reduction in breakdown voltage (BDV) [...]

Experimental Study on the Compressive Behavior of Fiber-Reinforced Ceramsite Concrete
Published on 2025-02-16 by Fei Gu, Congqi Li, Xin Wang, Yang Yang, Hushan Liu @MDPI
Abstract: Ceramsite concrete is a kind of green building material with advantages such as low weight, heat insulation, and fire resistance. However, it has low strength, high brittleness, and the problem of aggregate floating. In this study, by adding polypropylene fibers and optimizing the preparation process, the mechanical properties of ceramsite concrete have been significantly improved, which is of great significance for promoting the application of this material in the engineering field. Through uni[...]
Our summary: Study on improving mechanical properties of ceramsite concrete through fiber reinforcement. Analysis of failure characteristics and stress-strain relationships. Effects of strength grades and fiber contents on peak stress, peak strain, ultimate strain, and elastic modulus. Development of a correction model for stress-strain curve.

Experimental Investigation of Fire—Technical Characteristics of Selected Flame Retardants for the Protection of Wooden Structures
Published on 2025-02-06 by Patrik Mitrenga, Miroslava Vandl�?kov�, Milan Kon�rik @MDPI
Abstract: This study evaluates selected flame retardants on the basis of their influence on the change of fire-technical parameters of soft and hard woods (spruce and oak) during exposure to a flame heat source. The parameters evaluated were mass loss, mass loss rate and depth of the charred layer. The experiments were carried out on simple test equipment on which the samples were exposed to direct flame while their mass was monitored. The measured data and their statistical evaluation showed a significan[...]
Our summary: This study evaluates the technical characteristics of selected flame retardants on soft and hard woods, analyzing mass loss, mass loss rate, and depth of charred layer. Results show significant differences between inorganic salt-based and intumescent flame retardants, with the latter showing higher efficiency in increasing fire resistance.
