【答案】：Caron and graphite fibers are different in carbon content, pyrolyzing temperature, and modulus of elasticity. Graphite fibers have higher carbon content, pyrolyzing temperature and modulus of elasticity than carbon fibers.
The effects of transverse shear modulus, loading localisation, panel thickness and anisotropy on the stresses and displacements in the panel are examined and discussed. 展开 关键词: Three-dimensional elasticity Sandwich panel Functionally graded material Analytical modelling ...
Parameter studies on modulus of elasticity in three- and four-point bending. Abstract Ceramic–polymer composite materials are used throughout materials science, but theoretical models which take into account the microstructural design to predict their mechanical properties are still not fully developed. ...

In addition to room temperature data, the temperature dependencies of the Young's modulus (Y) and the shear modulus (G) were determined up to 600°C (873°K). The measured values for the resonant frequencies decreased with increasing temperatures, which resulted in correspondingly low moduli. ...
