Low-cost preparation and frictional behaviour of a three-dimensional needled carbon/silicon carbide composite

Phenolic resin impregnation was combined with liquid silicon infiltration to create a carbon/silicon carbide composite. The potential application for this material is in disc brakes in vehicles due to their oxidation resistance and friction behaviour. The density of the composite was altered until a final value of 2.10g/cm3 was achieved. The thermal conductivity of the composite was measured using the TPS method, and was determined to be 48.72 W/...

Rheology and Thermal Conductivity of Diamond Powder-Filled Liquid Epoxy Encapsulants for Electronic Packaging 

Diamond powders with various particle sizes were dispersed in an epoxy resin in an effort to increase its thermal conductivity. Dispersion of a mixture of particle sizes from 1 to 100 µm resulted in a thermal conductivity of 4.1 W/m·K which is a substantial increase in comparison to the thermal conductivity of the pure epoxy. The electronic device junction temperature between a Si PiN diode chip and a 64 vol. % diamond-epoxy flowable ...

Structure and oxidation resistance of micro-cellular Si–SiC foams derived from natural resins

Si-SiC composite foams were prepared using tannin-based foams as templates. The foams were prepared by four different methods for the determination of which method would best produce a foam with a pore size under 200 µm. The foam samples were characterized by SEM, XRD, and Raman spectroscopy, and the thermal conductivity of one of the foams was investigated by the transient plane source method. It was found that direct infiltration of ...

Systematic studies of tannin–formaldehyde aerogels: preparation and properties

A variety of tannin-formaldehyde aerogels were produced in order to examine the effects of pH and dilution during their manufacture. The authors produced a phase diagram that could describe them. Extensive physical property characterization was performed on the sample aerogels, including porosity, thermal conductivity, volume shrinkage, BET surface area and microscopic texture. Conditions under which the highest surface area and pore volumes were produced were identified. The TPS instrument was ...

Effects of carbon fillers on the thermal conductivity of highly filled liquid-crystal polymer based resins

Carbon/liquid-crystal polymer composites were formulated. Composites containing one of three types of carbon filler, composites containing two types of carbon filler, and composites containing all three types of carbon filler were prepared to test not only the effect of each filler on the thermal conductivity of the composite, but also the effect of combining fillers. The anisotropic method on a TPS system was used for the thermal conductivity measurements. ...
