Heat generation in an exothermic reaction during the curing process and low thermal conductivity of the epoxy resin produces high peak temperature and temperature gradients which result in internal and residual stresses, especially in large epoxy samples. In this paper, an optimi
Fiber nonlinear predictive model for combined bending-compression loading of an orthogonal plane weave composite laminate structure
To increase understanding of damage evolution in advanced composite material systems, a series of large deflection bending-compression experiments and model predictions have been performed for a woven glass-epoxy composite material system. Theoretical developments employing both
Multiphysics Modelling for Electronics Design
The future of many companies will depend to a large extent on their ability to initiate techniques that bring schedules, performance, tests, support, production, life-cycle-costs, reliability prediction and quality control into the earliest stages of the product creation process.
Genotoxicity of 1,3-butadiene and its epoxy intermediates.
Current risk assessments of 1,3-butadiene (BD*) are complicated by limited evidence of its carcinogenicity in humans. Hence, there is a critical need to identify early events and factors that account for the heightened sensitivity of mice to BD-induced carcinogenesis and to deter
Modeling and Characterization of a Graphite Nanoplatelet/Epoxy Composite
A micromechanical modeling procedure is developed to predict the viscoelastic properties of a graphite nanoplatelet/epoxy composite as a function of volume fraction and nanoplatelet diameter. The predicted storage and loss moduli from the model are compared to measured values fro
Spray and Cooling Dynamics of Cryogen Sprays Impinging on a Human Skin Model
The objective of the present work is to correlate the timedependent flow characteristics of cryogen sprays to the induced thermal dynamics at the surface of a human skin model. First, a numerical analysis to evaluate our skin model is carried out. Next, diameter and axial velocit
Evaluation of the Performance of the Composite Bamboo/Epoxy Laminated Material for Wind Turbine Blades Technology
Global energy sources such as coal and oil are limited, and the burning of such fossil resources creates pollution problems. Wind energy offers one of several promising clean alternatives to carbon-based fuels. However, the composite materials currently available for producing wi
The toughness of epoxy polymers and fibre composites modified with rubber microparticles and silica nanoparticles
The present paper investigates the effect of adding silica nanoparticles to an anhydride-cured epoxy polymer in bulk and when used as the matrix of carbonand glass-fibre reinforced composites. The formation of ‘hybrid’ epoxy polymers, containing both silica nanoparticles and carb
Molecular Modeling Approach to Prediction of Thermo-Mechanical Behavior of Thermoset Polymer Networks
Molecular dynamics and molecular mechanics simulations have been used to study thermo-mechanical response of highly cross-linked polymers composed of epoxy resin DGEBA and hardener DETDA. The effective cross-linking approach used in this work allowed construction of a set of stre
Polymer Composite Reliability Requirements for Large Space Structures
Long-life (10-30 years) large space structures are considered by NASA for a number of future earthorbiting missions. The use of very thin graphite-fiber composites have been considered as structural m~terials for the fabr~cation o~ these structures. A combination of analytical an
