Innovative High Thermal Conductivity Epoxies: Research Insights and New Developments

This document presents research findings on commercially available high thermal conductivity epoxies. It discusses calculations of electrical conductivity based on resistivity values, the importance of new epoxy ideas, and the necessity to create products using nanoparticles, specifically carbon nanotubes. It explains how thermal conductivity improves with increased composite material volume and differentiates between 1D and 2D architectural fiber alignments in the epoxy structure. Insights are provided from prior research and current challenges in commercial applications.

  1. High Thermal Conductivity Epoxies Jeff Wiseman 12/15/09

  2. Research on commercial epoxies New (Epoxy) Idea

  3. Notes • Commercial Epoxies • Electrical Conductivity calculated from a given value for electrical resistivity • First epoxy, with (FNAL), was in a list of epoxies researched by C.M. Lei at FNAL in 2000 • All are available for purchase from the manufacturers listed • New Epoxy Idea • After much searching, cannot find any commercial use of this product, must create it ourselves • Because the epoxy uses nanotubes, this thermal conductivity is either in 1 or 2 directions only, the 2 being in a plane. • As the volume % of the composite material increases, the thermal conductivity increases as well

  5. Thermal Conductivity of Composite Material cont. 1D

  6. Chen and Ting, Carbon.40(02)359 Thermal Conductivity of Composite Material cont. • Architecture • 1D architecture is when all fibers are aligned in the same direction • 2D architecture is when fibers are aligned in two directions, such as X and Y, that are in-plane perpendicular to each other
