Book excerpt: "This thesis aims to further understand the interfacial interactions in polymer-ceramic composites, identify ways to improve the interphase, and create high performance composites. Here we report three different polymer-ceramic systems with a focus on improving the mechanics and thermal properties of the final composite. The first system focuses on improving the strength of hydrogel-based composites using magnetically aligned micro-scale ceramic reinforcements. Here we have shown that the alginate-hydroxyapatite interphase successfully transfers stress from the hydrogel to the micro-ceramic reinforcement introducing a new class of load bearing tissue scaffolds. In addition, the mechanical properties of the hydrogel are tailorable depending on the filler orientation by using magnetic manipulation techniques. Finally, we have shown that hydrogels with perpendicular alignment exhibit high ductility, suggesting an exciting new toughening mechanism for fiber reinforced composites. In the second system, a semi-crystalline polymer matrix is reinforced with ceramic alumina micro-platelets. The matrix-filler interface is directly improved by locally crystallizing the polymer matrix using nanofiller nucleating agents, creating a hierarchical stiffness gradient between the matrix and the polymer. In this work, we use a combination of polypropylene, alumina, and carbon nanotubes, however the fundamentals of this system can be applied to a variety of different material combinations. We have successfully shown that a novel method to tailor the interphase between alumina and polypropylene using nanoparticle adsorption and local polymer crystallization techniques can be used to create a hierarchical stiffness gradient. This chapter also shows that the crystal nucleation and growth mechanisms match that of polypropylene-CNT filled systems, even when the CNT is adsorbed to the flat alumina surface. Finally, the locally crystallized polymer will likely improve the thermal heat transfer by introducing higher density polymer region immediately surrounding the filler. In the third system, the thermal conductivity of thermoset composites reinforced with ceramic filler is discussed. Thermal conductivity of polymeric materials is inherently low, therefore introducing high thermal conductivity ceramic filler improves the overall thermal properties. Here we discuss the most important aspects to creating these composites, including filler alignment, geometry, and introducing thermal pathways by creating a percolated network with the ceramic filler. A novel method to drive percolation in single layer, hBN-epoxy composites via Marangoni induced assembly is shown. Thermal spreading test results show this method of aligning and percolating the hBN platelets significantly increases the thermal heat transfer through the interphase. Finally, this chapter shows an application-based example of how thermal heat spreaders can be used in place of traditional metal heat management solutions. This thesis first discusses the importance of tailoring interphases in discontinuous composite materials. Following a detailed discussion on composite materials, we then introduce each individual system, review the current state of our research and key results, and discuss proposed methods to further improve the interfacial interactions and show property improvements in the final composite system"--Author's abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Composite materials are traditionally designed for the mechanical properties, due to their structural applications. However, composite materials are increasingly used in non-structural applications, such as electronic packaging and thermal management. Moreover, structural composite materials that are multifunctional are increasingly needed, due to the demand of smart structures and the importance of weight saving. As a consequence, structural materials that can provide electronic functions are needed. Thus, electronic functions are desirable for both non-structural and structural composite materials.

Download or read book Polypropylene Handbook written by József Karger-Kocsis and published by Springer. This book was released on 2019-03-18 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book extensively reviews Polypropylene (PP), the second most widely produced thermoplastic material, having been produced for over 60 years. Its synthesis, processing and application are still accompanied by vigorous R&D developments because the properties of PP are at the borderline between those of commodity and engineering thermoplastics. Readers are introduced to various tacticities and polymorphs of PP, and their effects on structural properties. Further, the book addresses the control of optical properties using nucleants, provides strategies for overcoming the limited cold/impact resistance of PP, examines in detail the effects of recycling, and presents guidelines for the property modification of PPs through foaming, filling and reinforcing with respect to target applications. Special attention is paid to descriptions and models of properties as a function of morphological variables. Last but not least, the book suggests potential practical applications of PP-based systems, especially in the packaging, appliances, building/construction, textile and automotive sectors. Each chapter, written by internationally respected scientists, reflects the current state-of-art in the respective field and offers a vital source of information for students, researchers and engineers interested in the morphology, properties, testing and modeling of PP and PP-based systems. The content is indispensable to the appropriate application of PPs and related composites.
