Thermal Conductivity Of A Composite Laminate

One dimensional thermal conduction is solved for composite laminate and the layerwise temperature distribution is calculated first.

Thermal conductivity of a composite laminate. This research investigates the thermal conductivity im provements of epoxy resin using carbon nanotubes cnts and aluminum nanoparticles alnps at high loadings. The thermal conductivity of composite laminate by introducing 10 wt fuzzy mat with 300 to 400 μm long pitch based carbon fiber filler was up to 1 2 w m k which was 216 higher than the thermal conductivity of the control sample which was 0 38 w m k. In addition to these effects chopped carbon fiber fillers also occupy the inter tow area and form direct conductive network. The thermal conductivity of the composite panel is predicted with very high accuracy r 2 0 995.

The key aim of this thesis is to model the thermal conductivity of practical composite laminates with respect to lamination imperfections as measured by. Information provide by boedeker plastics. Red seal electric stocking fabricator of non metallic. 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.

G10 fiber reinforced composite. Thermal conductivity is the ability of material to conduct heat through it. G 10 and similar fiberglass reinforced thermosets are sometimes known as garolite. On the other hand thermal resistivity is reciprocal of thermal conductivity.

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. A third model to predict the overall laminate thermal conductivity is introduced.

For graphite filler modified composite laminate the intrinsic thermal conductivity of graphite and bridging effect result in the slight increase of through thickness tc.

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. The high in plane thermal conductivity promotes heat spreading but low out of plane thermal conductivity hinders heat removal. The principle of complementary virtual work is employed to develop the governing equations.
