摘 要
複合材料雖具有質量輕、高勁度/重量比等優點，且逐漸取代傳統之金屬材料，但複合材料對於耐衝擊性質卻相當敏感，故本文主要係針對衝擊及溫度效應，對複材之機械性質影響進行實驗探討。
本文使用之試片為碳纖維/聚二醚酮之熱塑性基複合材料，其疊序含 之十字疊與 之類似均向疊兩種，採自由落錘式之衝擊試驗，衝擊條件有0.8m及1.6m兩種，衝擊後再施以靜態拉伸試驗，拉伸試驗之溫度則有常溫(25oC)、75oC、125oC及145oC等四種參數。在整個實驗過程中，除了探討衝擊及拉伸試驗之破壞機制外，並分析溫度、衝擊效應在不同疊序之極限強度及彈性模數之變化。
經由實驗結果之探討，本文獲得下列之重要結果﹕碳纖維/聚二醚酮複材在承受衝擊效應後之破壞，係由複材在衝擊區域由張力邊(衝擊背面)沿厚度方向往壓力邊(衝擊面)產生橫向裂縫而肇始，且在相同衝擊條件下， 試片之裂縫長度大於 試片。當衝擊高度增加，將使得複材之極限強度衰退幅度增加，其中， 十字疊試片在未承受衝擊或溫度效應時，雖具有較佳之機械性能，但衝擊及溫度效應造成此類試片之機械性能衰退較 之類似均向疊試片嚴重。

關鍵詞﹕複合材料、衝擊、溫度、極限強度、彈性模數、破壞。

Abstract
In this paper, the mechanical properties of carbon-fiber reinforced polyether-ether ketone (PEEK) with and lay-up subject to impact and temperature reaction have been investigated.The drop-weight impact tests were performed by a 4mm diameter semi spherical nosed projectile. Incident impact height adopts 0.8m and 1.6m incident height. After impact testing, the static tension tests were performed to measure the ultimate strengths and elastic modulus at 25℃、75℃、125℃、145℃,so that the effects of stacking sequence and the damage mechanism subjected impact at elevated temperature was obtained.
By the parametric study and research , there are very important results as follow: The destructive crack of AS4/PEEK laminates subject to impact were arised from the tension sides toward the pressure sides, and the lay-up was more serious than the lay-up.
Although more excellent ultimate strength than the lay-up, the must be quantities of decay When the incident height increase as well as elevated temperature.

Keywords: Composite, Impact, Temperature, Strength, Elastic Modulus,
Fracture.
