Get the original essay Organic polymer modification adds to add-ons, with few exceptions, a multiphase system containing additives embedded in a continuous polymer matrix . The combination that results from a single microstructure or a single microstructure, which is the cause of the symptoms. The main reason for using additives is: Improvement and control of processing characteristics. Modification or improvement of properties. Overall cost reduction Types and components of polymer composites: A polymer composite is a mixture of a polymer and an organic or inorganic additive with geometric certainties. namely (flakes, spheres, fibers and particles). Therefore, they have more than one component and two or more phases. They are incorporated into the polymer in a geometric arrangement that spans the entire size of the product. Thermoset laminate is a familiar example, based on a recognized fiber, generally classified as a high performance polymer composition, or a large compound due to the length of the fiber or ribbons. In another aspect, the additive may be discontinuous (short), such as short fibers (e.g., length). Composites can be classified based on their purpose or application. For example, someone can distinguish between two types of biocomposites. are intended for ecological applications and are a combination of natural fibers or particles with polymer matrices from renewable and non-renewable resources and they are characterized by the degree of environmental degradability of the composites. Biocomposites for biomedical applications are combinations of biostables. and biodegradable polymers with inert and bioactive fillers that are intended for use in orthopedic, bone regeneration, or tissue engineering applications. Reinforcements that are much stronger and stiffer than polymer primarily increase strength and modulus. a serious effect on thermal expansion, transparency and stability, etc. Continuous composites typically have long fibers or ribbon reinforcements in thermoset matrices; when prepared in certain geometric patterns, they can become the main component of the composite. In the case of discontinuous composites, directional reinforcing agents, namely flakes or short fibers, are mixed in various directions and geometric patterns defined by selected processing and molding methods, usually injection molding or die casting. extrusion. However, it should be noted that manufacturing methods for continuous oriented fiber thermoplastic composites are available which result in very higher fiber contents, as used in high performance engineering polymer applications. Effects of fillers/reinforcements: Functions Traditionally, most fillers only slightly increase the modulus of polymers due to their unfavorable geometric characteristics, surface area or chemical composition, so that the strength (tension, bending) does not change . Their main contribution was to lower the cost of materials by swapping out the more expensive polymers. Another possible economic benefit was that the molding cycle was faster due to increased thermal conductivity and reduced rejected parts due to warping. On the other hand, thermal expansion and shrinkage of the mold.
