Abstract
Present work was designed to investigate the class of possible materials to be
compounded as thermally conductive composite as well as to be catered as thermal
interface material (TIM) for an improved thermal performance of a high power light
emitting diode (LED) headlamp, a product of OSRAM Opto Semiconductors. This
research was earned out to produce a closely packed ceramic and graphene filled hybrid
epoxy composite. The work was earned out by understanding the physical and chemical
behaviour of aluminium nitride (AIN), boron nitride (BN) and aluminium oxide
(AI2O3). Also a comparison of compatibility between two commercial epoxy matrices
has been presented in this work. The thermal conductivity of unimodal AIN, bimodal
A1N/BN and bimodal AI2O3 were investigated.
