The naturally available material such as Sisal has been using in several applications in fabricating composite materials due to its exceptional durability with a minimum wear and tear and due to its ability to stretch. Using sisal fiber as reinforcement to form sisal fiber reinforced polymer composites, strengthen the study of mechanical properties of the composites. In this project, we have enhanced the mechanical properties of the sisal/glass fiber incorporated with polyurethane. Polyurethane is an extremely versatile elastomer used in countless applications worldwide. It has some excellent properties like high abrasive resistance, wide range of hardness, high load bearing capacity, wide resilience range, flexibility, strong bonding properties which makes it an ideal choice in the field of composite preparation. In this study, the composite material is fabricated by mixing Polyurethane proportionally with the sisal/glass fiber. After the fabrication is done, it is planned to study the mechanical properties of the composite material using different testing tools like Universal Testing Machine, Izod test, and hardness tester.

The development of studying nanocomposites has grown up rapidly in the last decade. The objective of the current research is to study the influence of incorporating cellulose nanocrystals on the mechanical properties of polyester resins, as well as to develop continuous filament e-glass fiber-reinforced polyester nanocomposites, which combine traditional composites with the added advantages of nanocomposites. Cellulose nanocrystals were uniformly dispersed into the polyester resin by an ultrasonic processor. The incorporation and dispersion of cellulose nanocrystals were a state-of-the-art method aimed at overcoming poor dispersion problems at low weight fractions of nanoparticles. Three weight percentages of cellulose nanocrystals were prepared, which were 2%, 4% and 6%. Fatigue and tensile specimens were manufactured by resin transfer molding process. Cellulose nanocrystals were fully characterized by using X-ray diffraction, transmission electron microscopy, Fourier-transform infrared spectroscopy and zeta-sizer analysis. The optimum incorporation percentage of cellulose nanocrystals was used to prepare glass fiber-reinforced polyester specimens containing cellulose nanocrystals. Tensile and fatigue behaviors of glass fiber-reinforced polyester composites were evaluated by means of universal testing machine and rotating bending fatigue machine. A series of testing specimens for each property was examined in accordance with the corresponding ASTM and JIS standards. The experimental results showed that the addition of 4% cellulose nanocrystals to polyester matrix lead to the optimum tensile and fatigue properties. Mechanical properties were improved through the enhanced material design and proper selection of compatible nanoparticles, and adding cellulose nanocrystals in a weight fraction that does not affect the mechanical properties of glass fiber-reinforced polyester nanocomposites negatively. The presented design of material and geometry have shown promising results for wide range of applications, particularly in biomedical industry, energy and electronics.

Glass Fiber Reinforced

Glass fiber reinforced polymer(GFRP) composites are currently used in large numbers of diverse applications ranging from tip and engine strut fairings in aircrafts, building panels and dash boards in automotive vehicles, boat hulls in ocean vehicle structures, golf clubs and race helmets in sports equipment, etc. The service life of composite materials are influenced by the different adverse environment which leads to various failures like corrosion, fatigue, fracture, etc., results in loss of structural integrity due to environmental conditions. The investigations involved are to study the mechanical behaviour of these materials when subjected to various adverse conditions of the environment at different intervals of exposure due to change in moisture and temperature. Experiments were conducted on GFRP composites with and without exposing to different environment conditions of sea water. Tensile and flexural tests are conducted to predict the mechanical behaviour of both normal specimens and specimens exposed with sea water. Reduction in mechanical properties found due to maximum absorption of any liquid by the material. When temperature increases better in mechanical properties are noticed and at low temperature the composite behaves like a brittle.
