The process of cure of thermosets is rather complex, and good knowledge of the various steps and different problems is necessary for the user. For instance, the following basic facts characterise the cure of thermosets: 1. In the same way as rubbers, thermosets are generally polymerised and processed in a simple operation which involves the irreversible transformation of a low molecular weight resin in viscous liquid state into a solid network polymer. The process of cure is thus much more important for thermosets or rubbers than for thermo plastics, because if something goes wrong during the cure process of thermosets, the final products may have undersirable properties and will be of no use or value, while the thermoplastic material can be melted again to make a new material. 2. In contrast with rubbers, a high exothermic cure reaction is the aspect of fundamental importance in the cure process for thermo sets. This high enthalpy of cure associated with a rather low thermal conductivity can give rise to an excessively high tem perature which may cause discoloration and degradation of the material, and also to substantial temperature gradients. The mat erial is thus heterogeneous during the process of cure, and these temperature-time histories in the resin may have some effects on the properties of the final material. 3. Moreover, the increase in production following the reduction in time of the cure cycle necessitates the use of a higher mould temperature.

Mechanical Development Of Thermosets During Cure written by John Roberto Puentes Gil and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2017 with categories.
Novel experimental and modeling techniques to quantify and correlate the kinetic and mechanical development of thermosets during cure are evaluated in this work. Commercial epoxy adhesives and prepregs are analyzed using standard protocols and improved protocols proposed here. First, the use of initial fast ramps in heat flux differential scanning calorimetry (DSC), up to 500 K/min, was used to follow the isothermal kinetic development of adhesives. More complete kinetics were captured while mitigating cure during the heating step. This was achieved with the optimization of the electronic furnace parameters. The enthalpy spike at the dynamic-to-isothermic transition remains an issue. Preliminary empirical shifts are proposed to compensate the signal lag. This method was used to represent the kinetics in the time-temperature-transformation (TTT) diagram including correction for filler, moisture, and pre-cure history. The formal kinetic method was used giving a simpler model compared to the conventional Kamal-Sourour equation. Second, the moduli development was captured from the gel point up to the fully cured state in a single DMA three-point bending test. A new sample was used by sandwiching a partially cured plate between two fully cured plates of adhesive. Kinetic, viscosity, gel point and shrinkage information were used to delimit and select parameters, the upper, and lower bounds of the moduli. Sandwich beam elastic theory was used to quantify the moduli of samples during cure. This method reduced beam compliance and eliminated signal noise. The previous techniques still measured kinetic and mechanical development using different instruments, masses, sample geometries, and conditions. Third, to solve this problem, an in-situ method attaching ultrasonic transducers and a Raman probe to a mold chamber was used. The degree of cure and moduli were measured simultaneously giving a closer interpretation of the cure-mechanical development interaction. Raman spectroscopy captured more reaction at the initial and propagation stages compared to DSC analyses. It also measured more accurately the end stage governed by diffusion mechanisms. This work concluded by exploring warpage measurements using a laser measurement device. The method allowed for the capture of a 3D rendering of the mold and the final component. More accurate warpage was quantified for the case of angle distortion in L-shaped parts. The angle distortion was found to strongly depend on the profile thickness. Steps towards implementing the results of this work in a numerical simulation of warpage of composite parts are detailed.

This reference work compiles and summarizes the available information on epoxy blends. It covers all essential areas – the synthesis, processing, characterization and applications of epoxy blends – in a comprehensive manner. The handbook is highly application-oriented and thus serves as a valuable, authoritative reference guide for researchers, engineers, and technologists working on epoxy blends, but also for graduate and postgraduate students, polymer chemists, and faculties at universities and colleges.The handbook is divided into three parts and organized by the types of blends and components: Part I covers epoxy rubber blends, Part II focuses on epoxy thermoplastic blends, and Part III examines epoxy block-copolymer blends. Each part starts with an introduction, and the individual chapters provide readers with comprehensive information on the synthesis and processing, analysis and characterization, properties and applications of the different epoxy blends. All parts conclude with a critical evaluation of the applications, weighing their advantages and drawbacks. Leading international experts from corporate and academic research institutions and universities discuss the correlations of different epoxy blend properties with their macro-, micro- and nanostructures. This handbook thus offers a rich resource for newcomers to the field, and a major reference work for experienced researchers, the first of its kind available on the market. As epoxies find extremely broad applications, e.g. in oil & gas, in the chemical industry, building and construction industry, automotive, aviation and aerospace, boat building and marine applications, in adhesives and coatings, and many more, this handbook addresses researchers and practitioners from all these fields.
