Consider the materials listed below: 1. A continuous fiber-reinforced composite (FRC) with 30 vol% carbon fibers in an epoxy matrix; 2. An aluminum matrix composite (MMC) is reinforced with 25vol% carbon dispersoids; 3. Carbon ceramic material with 15vol % porosity. The table below gives the properties of the component materials. Use the rule of mixtures or other relationships to compute the density, Young's modulus (in different directions when needed) and the thermal conductivity (where possible) of the materials.
