Thermomechanical and dynamic mechanical characterizations indicated that both DDSQ and POSS could effectively lower the coefficient of thermal expansion by up to approximately 34% and considerably increase the storage modulus (up to 183%). Therefore, DDSQ and POSS are promising materials for low-stress encapsulation for electronic packaging applications. Keywords: polysiloxane-imide-containing benzoxazine; polyhedral oligomeric silsesquioxane epoxy; double-decker silsesquioxane epoxy; polymer nanocomposite 1. Introduction Compared with pristine polymer nanocomposites, hybrid organic–inorganic nanocomposites comprising of functional polymers as the matrix and nanoscale inorganic constituents have attracted greater interest in both academia and industry because of their tunable and generally more favorable thermal, mechanical, electrical, and barrier properties [1–3]. Upgrading current thermosetting polymers has become critical because of their utilization in various applications.

In this review article, thermoset of epoxy, unsaturated polyester resin, phenolic, melamine, and polyurethane resin have been conversed. Thermosets usually have outstanding tensile strength, impact strength, and glass transition temperature (Tg). Epoxy is the most widely explored class of thermosetting resins. Owing to high stiffness and strength, chemical resistance, good dielectric behavior, corrosion resistance, low shrinkage during curing, and good thermal features, epoxy form the most important class of thermosetting resins for several engineering applications. Here, essential features of imperative thermosetting resins have been discussed such as mechanical, thermal, and non-flammability. At the end, employment of thermosetting resins in technical applications like sporting goods, adhesives, printed circuit board, and aerospace have been included.

  • Synthesis and Characterization of In-Situ Nylon-6/Epoxy Blends
    Synthesis and Characterization of in-situ Nylon-6/Epoxy Blends A thesis submitted to the Division of Research and Advanced Studies University of Cincinnati In partial fulfillment of the requirements for the degree of Master of Science 2016 In the Materials Science and Engineering Program, The Department of Mechanical and Materials Engineering By Anushree Deshpande B.E Polymer, University of Pune, 2011 Committee Members: Dr. Jude O. Iroh (Chair) Dr. Relva C. Buchanan Dr. Raj M. Manglik 1 ABSTRACT Epoxy is a thermosetting polymer known for its excellent adhesion, thermal stability, chemical resistance and mechanical properties. However, one of the major drawbacks of epoxies is its inherent brittleness. In order to overcome this drawback, incorporation of a thermoplastic as a second phase has proven to improve the impact strength without affecting the mechanical properties of epoxy. Researchers in the past have studied polyamide/epoxy blends in terms of blend compatibility, thermo-mechanical properties and morphology via solution blending. The current research effort employs in-situ polymerization to synthesize polyamide/epoxy blends. Blends of various compositions were synthesized by introducing Ɛ-Caprolactam (monomer of nylon-6) in the prepolymer of epoxy. All blend fractions were cured by exposing them to the same time and temperature conditions; and characterized using Dynamic Mechanical Analysis (DMA), Fourier Transform Infrared Spectroscopy (FTIR), Brookfield Viscometry, Scanning Electron Microscopy (SEM) and Thermogravimetric Analysis (TGA). DMA results show an overall increase in glass transition temperature and storage modulus in the rubbery region. FTIR results reveal maximum epoxy curing up to 15 wt% monomer loading, beyond which the plateauing of the epoxy conversion is recognized.

Received: 3 April 2019; Accepted: 24 April 2019; Published: 26 April 2019 Abstract: Recently, 3D printing of fiber-reinforced composites has gained significant research attention. However, commercial utilization is limited by the low fiber content and poor fiber–resin interface. Herein, a novel 3D printing process to fabricate continuous fiber-reinforced thermosetting polymer composites (CFRTPCs) is proposed. In brief, the proposed process is based on the viscosity–temperature characteristics of the thermosetting epoxy resin (E-20). First, the desired 3D printing filament was prepared by impregnating a 3K carbon fiber with a thermosetting matrix at 130 °C. The adhesion and support required during printing were then provided by melting the resin into a viscous state in the heating head and rapidly cooling after pulling out from the printing nozzle. Finally, a powder compression post-curing method was used to accomplish the cross-linking reaction and shape preservation. Furthermore, the 3D-printed CFRTPCs exhibited a tensile strength and tensile modulus of 1476.11 MPa and 100.28 GPa, respectively, a flexural strength and flexural modulus of 858.05 MPa and 71.95 GPa, respectively, and an interlaminar shear strength of 48.75 MPa.
