Title: Deep-release of Epon 828 epoxy from the shock-driven reaction product phase

Abstract

A series of gas-gun experiments was conducted to obtain product isentropes for 70/30 weight percent Epon 828 epoxy resin/Jeffamine T-403 curing agent. Thin epoxy flyers backed by a low-density syntactic foam impacted lithium fluoride (LiF) windows at velocities up to 6.3 km/s, creating stresses in excess of those required for reaction (~25 GPa). Following this, a rarefaction fan from the back of the thin flyer reduced the pressure in the epoxy products. VISAR and PDV were used to measure the velocity of the epoxy/LiF interface. Numerical simulations using several different treatments for the reactant-to-product transformation were conducted and the results compared with measured wave profiles. The best agreement with experiment was obtained using separate tabular equations of state for the reactants and products and an irreversible transformation to products.

System for vacuum pouring of epoxy tensile and impact specimens with a study of the behavior of these specimens at 77 K and 293 K. [Epon 828, Epon 871, and Epon curing agent 2]

Technical Report Fitzpatrick, C. M. ; Stoddart, W. C.T.

The purpose of the investigation described in this report was to establish a suitable technique for vacuum pouring of epoxy test specimens and to study the behavior of these specimens at 77 K and 293 K. A series of tensile and impact tests was conducted using specimens made from the following resins: Epon 828, Epon 871, and Epon curing agent Z. These materials are of general interest to designers of magnets for cryogenic service. Some of the applications that may be considered are: structural support, spacing, electrical insulation, and thermal insulation.

Dynamic response of Epon 828/T-403 under multiaxial loading at various temperatures

Journal Article Chen, W ; Zhang, X - Journal of Engineering Materials and Technology

The mechanical response and failure behavior of Epon 828/T-403 epoxy were experimentally obtained over a strain rate range of 1.7 {times} 10{sup {minus}5} to 4.7 {times} 10{sup 3} s{sup {minus}1} and a temperature range of {minus}190 to 100 C. Compressive loads were applied in both uniaxial and multiaxial manners. A modified split Hopkinson pressure bar was employed to perform dynamic experiments, whereas an Materials Test System (MTS810) was used to conduct experiments under quasi-static loading conditions to establish the trends in strain-rate sensitivity. Multiaxial compression was achieved by installing snug-fit steel sleeves on the lateral surfaces of the cylindrical polymermore »« less

Increasing the Lifetime of Epoxy Components with Antioxidant Stabilizers

Technical Report Narcross, Hannah ; Redline, Erica Marie ; Celina, Mathias C. ; ...

Epoxy thermoset resins are ubiquitous materials with extensive applications where they are used as encapsulants, composites, and adhesives/staking compounds used to secure sensitive components. Epoxy resins are inherently sensitive to thermo-oxidative aging, especially at elevated temperatures, which changes the bulk properties of the material and can lead to component failure for example by cracking due to embrittlement or by adhesion failure between the epoxy and filler material in a composite. This project investigated the effects of three commercial antioxidants (Irganox^® 1010 (I-102), butylated hydroxytoluene (BHT), or Chisorb^® 770 (HALS)) at two different loadings (2.5 and 5 wt%) on the mechanicalmore »« less

Shock and Release Response of Unreacted Epon 828: Shot 2s-905

Technical Report Pisa, Matthew Alexander ; Fredenburg, David A. ; Dattelbaum, Dana M. ; ...

This document summarizes the shock and release response of Epon 828 measured in the dynamic impact experiment 2s-905. Experimentally, a thin Kel-F impactor backed by a low impedance foam impacted an Epon 828 target with embedded electromagnetic gauges. Computationally, a one dimensional simulation of the impact event was performed, and tracer particles were located at the corresponding electromagnetic gauge locations. The experimental configuration was such that the Epon 828 target was initially shocked, and then allowed to release from the high-pressure state. Comparisons of the experimental gauge and computational tracer data were made to assess the performance of equation ofmore »« less

Shock characterization of epoxy: 42 volume percent glass microballoons

Technical Report Weirick, L J

In the late 1960's, a series of shock experiments were done on ceramic-filled epoxies. The results from the shock characterization of these mixtures were compared to unfilled epoxy with {rho}{sub 0} = 1.185 g/cm{sup 3}. In that the volume percent fill was kept essentially constant, the shock Hugoniots formed a consistent family of curves relative to their initial densities. The present study examined the shock characteristics of an anhydride-cured epoxy (Epon 828 base) filled with approximately 42 volume percent glass microballoons (GMB) with a density of 0.94 g/cm{sup 3}. The Hugoniot relationship was determined between the shock pressures of 0.5more »« less
