The objective of work was focused to investigate microstructure of polyurethane foam and cyclic crushing strength of its sandwich structure which made of sisal / coir / bamboo / glass fabrics as reinforcement with polyester resin to form composites skin. The tested sandwich panels were constructed four type of FRP faceplates made of sisal / coir / bamboo / glass fiber reinforcements impregnated...

Coir pith is an organic matter which originates from the tropical hemisphere, especially from southeast Asia where coconut oil production is extensive. For professional oil winning companies, the husk of the nut is a waste product. These coconut husks mainly consist of coir pith and coir fibers. Initially, coir pith was considered a waste but now research has established widespread applications...

A large diameter triaxial sample of 61.9 mm was made by adding coir fiber into red clay. The range confining pressure 50–200 kPa; content 0.1%–0.4%; and length 10–40 mm. By varying the pressure, length, unconsolidated undrained tests were used to study shear strength variation law fiber-reinforced soil. experimental data processed establish a linear model segmental elastic modulus, analysis det...

Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different para...

The purpose of the study is to delineate the impact of national and industry-specific government interventions and the influence of political parties in power. The study employs an interrupted time series design from the annual national coir export data (1970-2012) published by the Coir Board. The study concludes by highlighting that the significance of economic environment has a greater impact...

With the growing environmental problems and depletion of petroleum resources, there is an urgent demand for the biorenewable, sustainable, and environmentally friendly composite materials. Here, we report a green coir fiber composite with specific mechanical properties superior to that of other reported natural fiber/polymer composites. After treatment, both strength and toughness of the compos...

In recent years, composite material replaces conventional like metal, wood etc due to its light weight, high strength weight ratio and stiffness properties. Natural fibers coir, bamboo fiber, banana plant fiber has low cost, easily availability less harmful human. this work, coir is used as a reinforced material. Composites were prepared with different of epoxy resin. To find the effect on mech...
