“…There has been increasing demand for highperformance composites with near-zero thermal expansion [1]. In such composites, thermal expansion of one component may be compensated by a thermal contraction of other components [2]. Since most materials expand thermally, there has been extensive search for materials with a negative thermal expansion coefficient.…”

Thermal Contraction of Carbon Fullerenes and Nanotubes

We perform molecular dynamics simulations to study shape changes of carbon fullerenes and nanotubes with increasing temperature. At moderate temperatures, these systems gain structural and vibrational entropy by exploring the configurational space at little energy cost. We find that the soft phonon modes, which couple most strongly to the shape, maintain the surface area of these hollow nanostructures. In nanotubes, the gain in entropy translates into a longitudinal contraction, which reaches a maximum at T approximately 800 K. Only at much higher temperatures do the anharmonicities in the vibration modes cause an overall expansion.

“…Ito et al [1] have presented an attempt at tailoring thermoplastic laminates with nearzero coefficients of thermal expansion in one particular in-plane direction by using conventional low-cost glass fibers. Trende et al [2] have investigated residual stresses and dimensional changes in the compression-moulded glass-mat-reinforced thermoplastic (GMT) parts.…”

In this study, an elastic-plastic stress analysis is carried out on a steel fiber-reinforced thermoplastic composite disc under uniform thermal distribution. The composite disc is reinforced by steel fibers curvilinearly. Its mechanical properties are obtained by strain gauges and Instron test machine. The modulus of elasticity in the tangential direction is measured by fitting a solid disc to the composite disc, exactly. However, other material properties are found approximately. The material is assumed to be non work hardening. Stresses are determined for uniform temperature distribution. The magnitude of the tangential stress component in polar coordinates is the highest at the inner points of the disc. Plastic solution is performed numerically. Plastic region begins at the inner surface of the disc. The residual stress component of the tangential stress is the highest at the inner surface of the disc.
