本研究利用改良式薄膜疊層法 (Modified film stacking method) 配合熱壓製程，成功製備出部分樹脂含浸量 (Partially-impregnated) 與全樹脂含浸量 (Fully-impregnated) 的熱塑型短紗碳纖維補強聚碳酸酯樹脂(Polycarbonate, PC) 複合材料及熱固型短紗碳纖維補強環氧樹脂(Epoxy, EP) 複合材料。四種複合材料分別記名為: PC-P、PC-F、EP-P、EP-F。利用盤對盤 (Disk-on-Disk) 的接觸模式於乾式環境下進行摩擦與磨耗測試。第一部分:探討不同表面形貌與樹脂類型對於磨潤性質的影響。第二部分:針對PC-P與EP-F複合材料添加氮化鋁 (Aluminum nitride, AlN) 粉體至表面，探討粉體對於動態磨潤性質的影響外，並以動靜摩擦測試探討各材料之基礎摩擦特性。

第一部分結果: Alambeta測試得到，不同樹脂含浸量與形貌結構間，以EP-P複合材料熱性質最佳。磨潤實驗結果顯示，動態摩擦係數首要影響因素為高分子特性，次要因素為 S_mr1 以及 S_k 等表面粗糙度參數。四種複合材料的動態摩擦係數皆隨著轉速及壓力的增加而逐漸下降，且其與材料表面形貌、介面溫度有關聯。而磨耗率主要影響因素為樹脂含浸量。部分樹脂含浸量 (Partially-impregnated) 複合材料維持低磨耗率，而全樹脂含浸量 (Fully-impregnated) 複合材料的磨耗率隨著轉速與壓力提升而明顯增加。經由電子顯微鏡 (SEM) 觀察表面破壞形貌得知PC基複合材料主要為刮磨磨耗 (Abrasive wear)、黏著磨耗 (Adhesive wear) 和疲勞磨耗 (Fatigue wear) ；EP基複合材料主要為刮磨磨耗 (Abrasive wear) 和疲勞磨耗 (Fatigue wear) 。

第二部分:添加AlN結果顯示，PC-P-5%、PC-P-15% 複合材料的動態摩擦係數皆比PC-P低，其為複合材料型貌上的改變為主要影響。然而透過添加不同粉體含量 (5wt %、15wt %) ，後者動態摩擦係數提升約53.3 %、磨耗率下降約53.9 %。EP-F-AlN系列複合材料對於動態摩擦係數並無顯著差異，其磨耗率增加約84.1 %。

結果顯示，部分樹脂含浸量 (Partially-impregnated) 複合材料於本實驗的測試條件下依舊擁有較優異的磨潤特性，其中以PC-P複合材料最為優異，其具有高摩擦、低摩耗之特性，可望與AlN粉體複合並應用於摩擦材料之潛能。

In this study, staple carbon fiber fabric reinforced polycarbonate (PC) - and epoxy (EP) - based composites with partially-impregnated and fully-impregnated resin were fabricated by modified film stacking method and hot pressing process. Four kinds of composites are called PC-P、PC-F、EP-P、EP-F, respectively. The friction and wear test on composites were investigated under the condition of unlubricated sliding with a disk-on-disk wear test machine. First part: the effect of the different topography and resin type are investigated. Second part: By adding the AlN particle into the surface PC-P and EP-F composite to discuss the effect on the tribology property, also discussed the basic frictional property of all material by Kinetic/Static friction test.

In the result of first part: The result of Alambeta test indicated the EP-P has the best thermal property between the difference of the impregnation ratio and surface topography. The tribology experimental results showed that the intrinsic property of polymer is the primary influence factor for dynamic friction coefficient, next in importance is peak material portion (Smr1) values, once more is core height (Sk) values. The dynamic friction coefficient for four materials decreased with increasing the sliding speed/applied pressure and depend on surface topography and temperature at the interface. However, the primary influence factor for the specific wear rate is the resin impregnation content. The partially-impregnated composites maintain a low specific wear rate, whereas that of fully-impregnated composites substantially increase with increasing the sliding speed/applied pressure. Scanning electron microscopy (SEM) observations of the worn surfaces revealed that the main wear mechanisms are abrasive, adhesive and fatigue wear for of PC-based composites, but are abrasive and fatigue wear for EP-based composites.

The result of second part: The dynamic friction coefficient of PC-P-AlN series composites are lower than the PC-P due to the main change of surface topography of composite. By adding the varied content of AlN particle (5wt %、15wt %), the latter one enhance 53.3 % of the COF and decrease 53.9 % on wear rate. The dynamic friction coefficients of EP-F-AlN series composite are no significant varied, and the wear rate increase 84.1 %.

The results proved that partially-impregnated composites exhibited better tribology properties under severe conditions, especially PC-P, which has high friction and low specific wear rate characteristic and potentially be combined with AlN particle and be used as friction material in the application.
