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.

Out Of Autoclave

Ultrasonic longitudinal wave propagation is studied in out-of-autoclave (OoA) carbon fiber–reinforced polymer composite material with varying levels of porosity contents. A combination of cure pressures and a solvent is used to produce specimens with void contents in the range of 0% to 22%. Ultrasonic measurements are made in through-transmission mode, and the data is processed to study various aspects of wave interaction with porosity in OoA specimens. The specimens with a wide range of void contents have enabled the study of broader trends of ultrasonic center frequency, wave velocity, and attenuation with respect to porosity. Results show ultrasonic center frequency and wave velocity are decreased linearly as the void content increases. The relationship of ultrasonic wave attenuation can be approximated by a logarithmic relationship when considering the full range of void content studied. Strength measurements of specimens with varying void contents are made using the flatwise tensile (FWT) test. It is observed that the strength rapidly decreases with increasing porosity. Correlations made between FWT strength, ultrasonic wave velocity, and attenuation are best described by logarithmic relationships. The data shows a potential for inferring strength knockdowns due to the presence of porosity based on ultrasonic measurements.
