In recent years composites have been the subject of many scientific and research projects, as well as many commercial programs. Growing global ecological and social concern, the high rate of depletion of petroleum resources and new environmental policy has forced the search for new composites and green materials, compatible with the environment. Moreover calotropisgigantea fiber is a waste product. In recent years, scientists and engineers have been working mutually to use the inherent potency and routine of the fibers and nanoparticles in combination with natural to produce a new class of bio-based composites. The special challenges for this type of bio-composites are their eco attributes that make them environmentally friendly, completely …show more content…
For example, resins that are cured through exposure to ultraviolet light are commonly used in fiber optics, optoelectronics, and dentistry. Industrial tooling applications use epoxy resins to make laminates, castings, fixtures, and molds. In the electronics industry, epoxy resins can be used to make insulators, transformers, generators, and switchgear. Around your home, epoxy resin can be valuable for repairing china, pottery, glass, wood, metal, and leather objects. It has a very strong and highly durable bond after it has set properly. Epoxy resins can be used as repair material for marine applications, but they should not be applied on the outer layer of a boat because UV light exposure will eventually cause the resin to deteriorate. Additionally, epoxy resin is valuable as a crafting supply. People who enjoy making miniatures sometimes use epoxy resin to simulate water when creating beach and ocean scenes, although smaller amounts of resin can be used to design replicas of soups, liquid drinks, and fishbowls to be used in a child's dollhouse. Jewelry makers use epoxy resin to create necklaces, pins, bangles, bracelets, earrings, and rings that feature embedded glitter for a fun
