Synthesis, chemical resistance, and water absorption of bamboo fiber reinforced epoxy composites

Abstract

Natural fiber reinforced polymer composites are being increasingly used in the civil infrastructure. They have tremendous applicability to bridge systems ranging from use in seismic retrofit and strengthening of existing structural components, either in all composite form, or in conjunction with conventional construction materials. Natural fibers are not only strong and lightweight but also relatively inexpensive. Among the various natural fibers, bamboo finds widespread use in housing construction around the world, and is considered as a promising housing material. In this article, bamboo fiber reinforced epoxy composite has been synthesized by hand lay up technique. Effect of fiber content on chemical resistance and water absorption of composites has been studied to find the industrial suitability of the composites. Scanning electron micrographs of composites were used for a qualitative evaluation of the interfacial properties of bamboo/epoxy composites. These results indicate that bamboo can be used as a potential reinforcing material for making low load bearing thermoplastic composites. POLYM.

Effects of water-heat water aging on epoxy composites containing nano-particles of ZnO

“…However, epoxy resin has some disadvantages, such as poor wear resistance and low weather fastness et al, which were limited its further application [5][6][7][8][9][10]. Epoxy resins can easily absorb water from their surroundings due to the threedimensional network structure, resulting in decreased performance [11][12][13][14][15][16].…”

Impact Strength, Water Absorption and Chemical Resistance of Untreated and Treated Cordia-Dichotoma Fiber/Polyester Composite

“…This is due to better bonding between the alkali treated fibers and the polyester matrix, which gives the composites better resistance to chemical dispersion. Based on this study, these composites can be considered for agricultural, automotive (interior parts), and domestic household applications [13].…”

“…Another set of composites such as the alkali treated fiber reinforced polyester composites (A 10, A 15, A 20, and A 25) of four different compositions (10wt %, 15 wt %, 20 wt %, and 25 wt % fiber loading) are made. After the curing process, test samples are cut to the required sizes as per individual test requirements [13].…”

“…The results confirmed that a water absorption pattern found to follow the pseudo-Fickian behavior. Anu Gupta [13] studied the water absorption and chemical resistance of bamboo reinforced polymer composites. This study concludes that water absorption increases with increase in fiber content and it follows Fickian behavior; chemical resistance decreases with an increase in the fiber weight ratio and was maximum for 10 weight percentage of fiber.…”

Properties and Morphologies of Epoxy Resin Based Composites Reinforced by Polyurethane and Graphene Oxide

“…Epoxy resin (EP) is classi ed as one group of the most important thermosetting polymers characterized by high temperature resistance 1) , electrical insulation 2) , chemical resistance 3) , and anti-corrosion performance 4) . However, EP is generally brittle polymers with poor toughness and damping property, which restricts its application.…”
