Recent advances in epoxy resin, natural fiber-reinforced epoxy composites and their applications

Abstract

The versatile characteristic of epoxy and its diversity made it suitable for different industrial applications such as laminated circuit board, electronic component encapsulations, surface coatings, potting, fiber reinforcement, and adhesives. However, the pervasive applications in many high-performance field limited the epoxy use because of their delamination, low impact resistance, inherent brittleness, and fracture toughness behavior. The limitations of epoxy can be overcome by incorporation and modification before their industrial applications. Currently, modified epoxy resins are extensively used in fabrication of natural fiberreinforced composites and in making its different industrial products because of their superior mechanical, thermal, and electrical properties. Present review article designed to be a comprehensive source of recent literature on epoxy structure, synthesis, modified epoxy, bioepoxy resin, and its applications. This review article also aims to cover the recent advances in natural fiber-based epoxy composites and nanocomposites research study, including manufacturing techniques and their different industrial applications.

A review on potential development of flame retardant kenaf fibers reinforced polymer composites

“…FRs are the chemical substance that are being added to materials both to constrain and delay the spread of fire after ignition or to discontinue the polymer combustion process . FRs have been classified based on their chemical constituents, ways of incorporation and their working mode as displayed in Fig.…”

Mechanical, water uptake properties, and biodegradability of polystyrene‐coated sisal fiber‐reinforced high‐density polyethylene

“…[8] Sisal fiber has been used extensively as reinforcement in several thermoplastic composites such as high-density polyethylene (HDPE), [9] polystyrene (PS), [10] polypropylene (PP), [11] and polyvinyl chloride. [12] Sisal fiber is used also for preparation of green composites with thermosetting [13,14] and elastomeric polymers. [15,16] HDPE is a petroleum derivative that is widely used in our daily lives such as in bottles, toys, packaging materials, chemical containers, and household goods.…”

Sisal fibril epoxy composite—a high strength electrical insulating material

“…A significant advantage is that the natural fibers would be simply disposed of at the end of their life cycle by decomposition or by recovery of their specific calorific value in heating chamber, which is not possible in conventional reinforcement such as glass fibers . Different types of natural fibers like sisal, flax, jute, banana, hemp, rami.e., coir, and pineapple leaf have been investigated for reinforcement . Sisal fiber is one of the most promising natural fibers for application where the combination of electrical and mechanical properties is required .…”
