Multimaterials for Advanced Structural Applications: Gerhard Ziegmann1; Maximilian Feyrer1; Sebastian Sdrenka1; Tobias Fischer1; 1Clausthal University Of Technology
The requirements for structural applications are increasing permanent, esp. under the aspect of weight reduction for saving energy in highly loaded structural applications. By using particle modified polymers there are different strategies to improve functionality. In the packaging industry monofilms, based on modified biopolymers will offer new possibilities for circular economy. Nanoparticle reinforced thermoset polymers will improve the characteristics of fiber reinforced polymers.The presentation will discuss different ways to use material combinations for advanced applications.

Investigation of Pineapple Leaf Fiber Reinforced Natural Rubber by Dynamic Mechanical Properties: Karine Mougin1; Budsaraporn Surajarusarn2; Gautier Schrodj1; Taweechai Amornsakchai2; 1CNRS - IS2M; 2Mahidol University
In Thailand, there are large areas of pineapple cultivation and pineapple leaf is a byproduct from which pineapple leaf fiber (PALF) may be extracted. PALF has high cellulose content and high mechanical properties. It can be used as alternative replacement for synthetic fiber. Aramid fiber is one of important synthetic fiber that is widely used in many applications. In this research, three concepts were used to improve the reinforcing efficiency of PALF. 1. pre-treatment to breakdown the fiber bundle to elementary microfiber, 2. treatments (silane, low molecular weight rubber) to modify the fiber surface to increase the adhesiveness of the rubber to the fiber and 3. incorporation of adhesion promoter having high polarity. Unidirectional composites were then prepared and the reinforcing efficiency evaluated at low strain using dynamic mechanical analysis and tensile test. With appropriate surface treatment and adhesion promoter, PALF displays clear potential as high performance reinforcing fiber.

Microstructural Characterization and Vibration Damping Behavior of Al-NiTi Composites: Namrata Gangil1; Arshad Siddiquee2; Sameera Mufazzal2; S. M. Muzakkir2; Sachin Maheshwari3; 1Ajay Kumar Garg Engineering College; 2Jamia Millia Islamia; 3Netaji Subhas University of Technology
Shape memory based smart NiTi particles were dispersed on the surface of AA6063 alloy by friction stir processing (FSP) to harness its functional property in vibration damping. The FSP was performed by using a high-speed steel tool and by varying tool rotational speed at three levels 710, 900 and 1120 rpm while keeping traversing speed at 50 mm/min. The NiTi composite so developed was microstructurally analyzed for adequacy of particle distribution. The microstructural analysis confirmed that the particles underwent significant fracturing during stirring action and were homogeneously distributed. The vibration damping characteristics were studied by exciting the vibration test samples of the functional material and the base metal. Modal analyses were performed on ANSYS to identify the mode and nature of vibrations and damping characteristics were estimated by calculating damping ratio. The vibration damping characteristics confirmed considerable improvement in the damping capacity of the fabricated NiTi based functional composites.

Improvement of Corrosion Resistance of A36 Steel Using SiC and TiB2 Thermally Sprayed Coatings
: Abhijeeth Nagaraj1; Adarsha H1; Hariprasad S A1; Ramkumar N P1; 1Jain University
Steel has been a primary material in construction and industrial applications. It has been affected by its inherent property of poor corrosion resistance when subjected to harsh conditions. This has been a major reason leading to reduction in the overall operational life of such steel-based components in service. Surface modifications are noted for being an effective solution to overcome these problems. To limit such damages, a study has been made to check the performance of Silicon Carbide and Titanium Diboride based coatings on A36 steel using Thermal Spray technique. The corrosion resistance of the developed coatings has been compared against an uncoated specimen. The application of coatings has shown an improvement in corrosion resistance, indicating that inert material-based surface modifications can be an effective way to improve the corrosion resistance in steel.
