Thermal Conductivity Of A Composite Laminate

Thermal conductivity of a polymer composite is a function of resin type fiber type and architecture fiber volume fraction direction of heat flow and service temperature.

Thermal conductivity of a composite laminate.

Information provide by boedeker plastics. A third model to predict the overall laminate thermal conductivity is introduced. However in the through thickness direction the thermal conductivity of the carbon fiber reinforced composite is no more than 1 w mk due to the laminate structure. The key aim of this thesis is to model the thermal conductivity of practical composite laminates with respect to lamination imperfections as measured by.

This research investigates the thermal conductivity im provements of epoxy resin using carbon nanotubes cnts and aluminum nanoparticles alnps at high loadings.

In addition to these effects chopped carbon fiber fillers also occupy the inter tow area and form direct conductive network. Fiberglass laminates is a fiberglass epoxy laminate usually specified when extremely high strength and consistent dimensional stability over tem. The thermal conductivity of the composite panel is predicted with very high accuracy r 2 0 995. The principle of complementary virtual work is employed to develop the governing equations.

For graphite filler modified composite laminate the intrinsic thermal conductivity of graphite and bridging effect result in the slight increase of through thickness tc. One dimensional thermal conduction is solved for composite laminate and the layerwise temperature distribution is calculated first. However in the through thickness direction the thermal conductivity of carbon fiber reinforced composite is no more than 1 wm 1 k 1due to the laminate structure. G 10 and similar fiberglass reinforced thermosets are sometimes known as garolite.

G10 fiber reinforced composite. Fr 4 is a fire retardant g 10 glass epoxy laminate that is used primarily in the printed circuit board industry. The high in plane thermal conductivity promotes heat spreading but low out of plane thermal conductivity hinders heat removal.
