Firefly Algorithm–Based Optimization of Processing Parameters for Enhanced Performance of Polymer Composite Materials
Abstract: Polymer composite materials are extensively used in aerospace, automotive, and oil & gas applications due to their high strength-to-weight ratio and design flexibility. However, achieving optimal mechanical and thermal performance strongly depends on precise control of processing parameters such as curing temperature, energy consumption, and material utilization. Conventional trial-and-error approaches often lead to excessive energy usage, non-uniform curing, and sub-optimal composite properties. To address these challenges, this paper proposes an …

Flame Spraying of Polymer-Abrasive Composites
Abstract: Polymer-based abrasive tools are distinguished by higher elasticity and resistance to chemically active media compared to tools with metal and ceramic binders. The former are effective at processing complex-profile and non-rigid surfaces. Tools based on coatings containing abrasive phenol- formaldehyde/epoxy resins and vulcanites are characterized by high cost and toxicity. In this paper, a study of composite flame-sprayed coatings, consisting of thermoplastic polymers and silicon carbide (volume ratio of 50-50), …

Comparative Study on Stabilization of Expansive Soil using Cement Kiln Dust and Ceramic Dust
Abstract: In India, expansive soils cover about 20% of total land area, these soils increase in volume (swell) during winter season and decrease in volume (shrink) during summer season. Due to this contradiction behaviour many civil engineering structures constructed on expansive soils get damaged severely, out of which pavement is the most because they are lightweight and extend over large areas. Stabilization of Expansive soil is of most importance, since to …
