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.

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.

Intumescent coating having improved low-temperature flexibility
Patent published on the 2024-07-04 in SA under Ref SA522441011 by R?HM GMBH [DE] (Janos Lotz [de], Dr Alexander Klein [de])
Abstract: The present invention relates to a novel reaction system for intumescent coating. Intumescent coatings are used in particular for fire protection of metallic building components, such as girders in building construction. In the event of a fire, such coatings undergo reactive foaming that results in the formation on the metal girder of a fireproof insulating layer having low thermal conductivity and that - through the insulation that this creates - retards any early, thermal-induced failure of sa[...]
