〔(±45°)_m/0°_(2n)〕_s层板的热膨胀性能和零膨胀的设计

THERMAL EXPANSION CHARACTERISTICS OF (±45°) m/0° n s LAMINATES AND ZERO EXPANSION DESIGN

复合材料的热膨胀性能和它的许多其它性能一样，可以进行理论计算和设计。本文采用直接建立力学分析模型的方法计算和讨论〔（±４５°）ｍ／０°２ｎ〕ｓ层板的热膨胀性能，并探讨层板纵向零膨胀的设计方法。

Thermal expansion properties of composite materials,just as many of their other properties,can be estimated theoretically and can also be designed.Using a direct mechanical analysis model.The thermal expansion characteristics of (±45°) m/0° 2n s laminates are discussed and a zero expansion design method is developed.
