Available in PDF, EPUB and Kindle. Book excerpt: There are three distinct types of epoxides in the SP-250 system. The epoxides were individually mixed with Monuron. Also, three-component mixtures, epoxide + Dicy/Monuron, were prepared with dicyandiamide. The mixtures were cured by differential scanning calorimetry. It was found that the isothermal heat of reactions of the two- and three-component systems were in reasonable agreement with the respective dynamic recations, consequently, the extent of isothermal cures could be determined from the two heating modes. The synergistic effect of dicyandiamide and monuron, on the curing process, was simulated by the isothermal reaction of two mixtures. A type of reaction Kinetics having the dimensions of temperature per time was evaluated in this report.

Download or read book Thermoset Modelling and Simulation Analysis with a Focus Towards Epoxies written by S. G. Hall and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work covers a number of aspects central to, and relating to molecular modelling and simulation. Section 1 introduces the diamine, 4,4-diaminodiphenylsulphone (DDS) and the epoxide monomers Bis[4-(glycidyloxy)phenyl]methane (BFDGE) and N,N-Diglycidyl-4- glycidyloxyaniline (TGAP) which are used in this research. The primary and side reactions are explained along with the description and origin of the known impurities. Molecular modelling concepts are explained, covering energy calculations, geometry optimisation and molecular dynamics (MD). The Polymer Consistent Forcefield (PCFF) is used throughout this work, Section 1 includes a comparison of common forecefields, ensembles, thermostats and barostats. Section 2 explains the experimental methodology used for the empirical measurement of glass transition temperatures (T g) using Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Thermal Analysis (DMTA). Also covered are the more technical and specific matters of this research such as how the impurities are modelled and how the molecular ratios are calculated. There are seven primary models built, based on four formulations. Epoxy A is an epoxy rich mixture of BFDGE, TGAP and DDS, Epoxy B is a stoichiometric mix of BFDGE and DDS, Epoxy C is also stoichiometric, but comprised from TGAP and DDS, Epoxy D is epoxy rich, but only uses TGAP and DDS. The Epoxy F, G and H formulations are the second generation models of Epoxy B, C and D respectively, the models differ from the originals slightly on a number of points. Molecular models were used to predict T g for comparison with empirical values. Two programs were written as part of this study, the first will process a molecular model, comprised of epoxy and amine monomer, returning a cured resin model, coded to simulate the epoxy and amine bonding reaction. The second is used to processed density vs. temperature data and determine the T g. The source codes for both programs are available as appendices in Section 6. Materials Studi~ by Accelrys" was used extensively for molecular modelling throughout this work. Section 3 contains the results and discussion from the DSC, DMTA, molecular modelling and lesser experiments. Owing to inter-model similarity, only 4 formulations were subject to thermal analysis. DSC measurements for T g yielded 215 QC for Epoxy II A, 161 QC for Epoxy Band 229 QC for Epoxy C, the DSC analysis of Epoxy D did not establish a value for Tg• The DMTA measurement ofTg gave good agreement for Epoxy A and Epoxy B, about 46 QC higher than DSC for Epoxy C and an average of 280 QC for Epoxy D. The closest simulations to the empirical values were Epoxy B (+3.0%), Epoxy C (+4.3%), Epoxy D (-5.0%) and Epoxy A (-6.0%). It was noticed the simulation of stoichiometric fo~ulations predicted lower, and epoxy rich models predicted higher than empirical measurements. The final sections include the summary (Section 4), discussion on possible further work (Section 5) and the appendices (Section 6).

Download or read book Micro and Nanostructured Epoxy Rubber Blends written by Sabu Thomas and published by John Wiley & Sons. This book was released on 2014-11-03 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epoxy resins are polymers which are extensively used as coating materials due to their outstanding mechanical properties and good handling characteristics. A disadvantage results from their high cross-link density: they are brittle and have very low resistance to crack growth and propagation. This necessitates the toughening of the epoxy matrix without impairing its good thermomechanical properties. The final properties of the polymer depend on their structure. The book focuses on the microstructural aspects in the modification of epoxy resins with low molecular weight liquid rubbers, one of the prime toughening agents commonly employed. The book follows thoroughly the reactions of elastomer-modified epoxy resins from their liquid stage to the network formation. It gives an in-depth view into the cure reaction, phase separation and the simultaneous development of the morphology. Chapters on ageing, failure analysis and life cycle analysis round out the book.

Download or read book From Biomass to Advanced Bio Based Chemicals Materials A Multidisciplinary Perspective written by Gabriel Paës and published by Frontiers Media SA. This book was released on 2020-04-01 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lignocellulose is the only renewable carbon source that can help replace oil-based chemicals and materials, in the process fighting global warming. However, because of its chemical and structural complexity, lignocellulose transformation into advanced products requires a better understanding of its composition and of its architecture at different scales, as well as a combination of physical, biological, and chemical processes, in order to render this transformation efficient and economically competitive. Tremendous efforts continue to be made toward the production of ethanol as a biofuel from various lignocellulosic feedstocks. Furthermore, recent successes have been achieved in extracting fibers to prepare composite materials that can compete with plastic fabrics. Importantly, lignocellulose chemistry can bring to the market original and complex chemicals that can lead to new applications, in particular when exploiting aromatic molecules or oligosaccharides from lignocellulose to produce solvents, surfactants, plasticizers, functional additives for food/feed/cosmetics, drugs, monomers, and polymers. In addition to this broad range of molecular products, fibers and particles fractionated from the lignocellulosic biomass are increasingly used to elaborate bio-based composite materials.

Download or read book Controlled Interphases in Composite Materials written by Hatsuo Ishida and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third International Conference on Composite Interfaces (ICCI-III) was held under the auspecies of ASM International, The Aluminum Company of America (Alcoa), The Edison Polymer Innovation Co. (EPIC), Case Western Reserve University, Nippon Glass Fiber Co., Nitto Boseki Co., Office of Naval Reserach (ONR), SAMPE Japan, Teijin Co., Mobay Co., Union Carbide Co., and Vetrotex Sain-Gobain. The underlying philosophy of the conference continues to be the promotion of fundamental understanding of the structure and role of composite interfaces. With the growth of composite interface studies, the research direction naturally changes from characterization and understanding of interfacial structure to controlling this structure. For this reason, the conference was subtitled, "Controlled Interphase Structure." The rather unfamiliar phrase "interphase" is used to emphasize the interfacial region whose properties are different from the bulk. The importance of the interphase to the mechanochemical properties has been rapidly recognized among composite researchers in recent years. The conference incorporated nine sessions. No concurrent sessions were planned because of the strong interest among panicipants and organizers to intennix researchers from different disciplines. Papers presented were redistributed in Pans I throught V. Because of this, both the conference and proceedings are not organized based on the traditional disciplines or materials, but rather around concepts.
