In this article, we study the process of polymerization of a modified ED-20 epoxy binder under conditions of highly filled systems. It is found that modifying additives affect the process of polymerization of the binder, increasing the degree of conversion of epoxy groups of ED-20 resin, speeding up the process of polymerization, and increasing the exothermic effect of the reaction. Curing in the presence of a modifying silicon-containing additive takes place in a mode that promotes the formation of a more ordered structure, creating opportunities for relaxation of internal stresses and favorable conditions for the formation of an ordered microstructure. The equations sufficiently fitting the measured points of the concentration of epoxy groups are calculated. We obtain the kinetic curves of curing, which illustrate the process of heat release of the ED-20 binder and the same system modified with mineral fillers. It is found that the heat release occurs more intensively when modifiers are introduced into the epoxy binder. It is derived that the experimental data of kinetics of heat release at considered time range can be sufficiently described by a parabolic equation.

Exploration of natural fiber‐reinforced polymer composites (NFRPCs) in cutting‐edge applications is due to phenomenal properties, such as lightweight, low‐cost, and environmental aspects. NFs can effectively compete to the synthetic fibers in terms of mechanical, thermal and acoustic properties. As a result, the invention and innovation of natural fiber (NF) composites for commercial purposes has increased dramatically in recent years to meet the growing demand of the industrial sectors. Materials are the cornerstone of any manufacturing industry. NFRPCs are a good alternative to conventional materials because of their relatively high mechanical properties and lower production energy. NFs decrease the cost of the material by 5% while reducing the weight of the composite by 10% and the manufacturing energy by 80%. A lot of work has been done to enhance NFRPCs' mechanical properties to overcome their drawbacks, such as poor fiber‐to‐matrix adhesion, thermal stability, and moisture absorption. However, for better mechanical properties, it is crucial to understand the fibers' embedded manufacturing technique and the appropriate fiber weight percentage with appropriate matrix. This review article discusses composites made of NFs providing a comprehensive and up‐to‐date overview of the field of NFRPCs, focusing on recent advancements in preparation techniques, improvements in mechanical properties such as tensile, flexural and impact strength of NFRPCs with various fiber types, fiber weight ratio, fiber‐to‐matrix ratio for appropriate engineering applications, and elucidating future research directions by analyzing trends and challenges in the field. The aim of this review article is to provide a deep evaluation of the progress made in the field of NFRPCs, with the ultimate goal of advancing knowledge and understanding of this field.

Finite element analysis of brittle materials in axial compression typically uses element deletion to allow continued global deformation post-element-failure. However, element deletion produces cyclic load-displacement curves that underestimate energy absorption and are not representative of a continuum system. Two key observations support the conclusion that results from an appropriately discretized model can be an adequate representation of a continuum system. Specifically, the frequency of the oscillations in the load-displacement curve is directly dependent upon element length in the loading direction, and the peak amplitudes of oscillations are mesh size independent. A method of post-processing the analysis results, by connecting the peak amplitudes of oscillations, is proposed and applied to a series of continuous carbon fiber composite crush tubes. The load-displacement curve, stable crushing load, and specific energy absorption of the post-processed results compare well to an experimental study of crush tubes with similar layups.
