摘要: 
  本文將使用鎖相熱影像法、脈衝熱影像法與逐步加熱法,以此三種加熱原理並透過有限元素法(ANSYS)模擬碳纖維複合材料與損傷區域之溫度變化,探討使用不同加熱頻率配合不同加熱瓦數之間的關係,和定義最有效的加熱時間與加熱溫度。本文以五個不同加熱頻率進行鎖像熱影像的加熱模擬,可以知道使用的加熱頻率越低,在厚度不大的材料中深層的缺陷越容易辨識。此方法會比脈衝熱影像法與逐步加熱法更容易檢測到較深層的缺陷。

  This thesis presents the thermographic studies via FEM simulation through three different kinds of heating methods (lock-in, pulse and step). Under investigating the relationship between thermographic results under different heating frequencies and heat fluxes, the most effective heating time and temperature are found. It is also found that the lower the heating frequency is, the easier the deeper defects of thin composite material can be identified. Simulation result also shows that it is easier to detect deeper defect by using lock-in thermographic method rather than by using pulse or step heating thermographic methods.
