composite materials

The main function of reinforcement agents is to provide strength to the composite structure. Based on reinforcement composites are classified into three types: Fibre Reinforced composites Laminar composites Particulate composites Fibre reinforced composites are, further, classified into composites reinforced with short staple fibres or with continuous filaments. The laminar composite consists of a varying number of layers of reinforced material with the matrix. Particulate composites are manufactured using particles, in the form of flakes or in powder dispersed in a matrix. 1. Fibre Reinforced Composites In fibre reinforced composites, natural or synthetic fibres are used as reinforcing materials in different forms and architectures. In these composites, fibre acts as the main load-bearing component. Fibre structure, length of the fibre, and fibre orientation towards applied load decide the performance of the composite. These types of composites are lightweight yet durable and rigid.

AI has shown immense potential and promise in solving problems that were previously assumed as a work of fiction. Let’s explore the various ways it is impacting the tech industry.

Laboratory flooding experiments showed the modified composite's superior performance, with a significant viscosity increase and 11 % higher oil recovery than unmodified chitosan. Advanced simulations further validated its effectiveness, surpassing native chitosan and traditional water flooding methods. Related Work Previous studies have extensively explored the applications of chitosan, a biodegradable polysaccharide derived from chitin, in enhancing oil recovery (EOR) within the petroleum industry. Chitosan's exceptional properties, including its solubility in acidic conditions and resilience to extreme environments such as high salinity and temperatures, have attracted significant interest. Previous research has also investigated various aspects of chitosan's effectiveness, including viscosity enhancement and interfacial tension reduction. Chitosan Composite Study The study employed chitosan, a commercially sourced polysaccharide, along with various chemicals, including

Biocomposite materials made of natural plant fibers are becoming a viable alternative to the use of synthetic ones such as glass fibers, thanks to many economic, ecological, and technical benefits. However, their massive use in the industry requires optimal control of their mechanical performances, which constitutes a real scientific issue to be overcome. Indeed, biocomposites suffer from an important variability in their mechanical properties because of their multiscale structure, natural growth conditions, and various processing parameters, in addition to eventual chemical treatments. Biocomposites are also highly sensitive to the surrounding environment in terms of humidity and temperature because of the hydrophilic properties of natural plant fibers. In this context, this Perspective aims to provide a critical look at the influence of the main factors that affect the mechanical properties of biocomposites in order to suggest some possible research outlooks that could contribute to
