  1. Smart materials and structure have definite requirements of sensor components and driving components, for example, they can adhere well to the matrix and have higher strength, fatigue strength, more broad scope of frequency response and faster response speed, etc. piezodielectric ceramics have characteristic of easily preparing, heat - resistance, wet - resistance, high strength and broad scope of frequency response, etc. furthermore, it has piezoelectric effect and inverse piezoelectric effect, namely it can produce electric potential energy when it is transformed by mechanical strength and its mechanical dimension can be transformed when voltage is put on it

    壓電陶瓷能與基體材料很好結合,具有制備容易、耐熱、耐濕、強度高、頻響寬等特點,另外它具有正壓電效應和逆壓電效應,即當它受到機械力變形時,能產生電勢,對它施加電壓時,能改變其機械尺寸,因此它在智能材料結構中既能用作傳感元件又能用作驅動元件。
  2. This dissertation focuses on how to develop a high performance damping mechanism based on multi - energy transitions, which is independent or little dependant with the viscoelasticity of polymer matrix. three sections are mainly included in this dissertation as follows : chlorinated polyethylene ( cpe ) / piezoelectric ceramic ( pzt ) / vapor grown carbon fiber ( vgcf ) composites ; cpe / 2, 2 ' - methylene - bis - ( 4 - methyl - 6 - cyclohexylphenol ) ( zkf ) / vgcf composites ; organic hybrids made from cpe and small molecules cpe / pzt / vgcf composites : the damping composites of multi - energy transitions mechanism were produced by mixing pzt and vgcf into cpe. in this system, the mechanical vibration energy that was transmitted to cpe was found to convert into joule ' s heat through conduction paths between vgcf in the polymer matrix, so the vibration fades away

    本論文主要包括三個方面的研究內容: ?氯化聚乙烯( cpe ) /壓電陶瓷( pzt ) /氣相生長碳纖維( vgcf )復合材料; ? cpe /雙[ ( 2 -羥基- 3 -環己基- 5 -甲基) -苯基]甲烷( zkf ) / vgcf復合材料; ? cpe基有機小分子混雜型復合材料cpe / pzt / vgcf減振復合材料:利用壓電和導電填料填充高聚物基體,當復合材料受到機械振動時,通過高聚物基體將機械振動能傳遞到壓電陶瓷粒子上,利用壓電陶瓷的壓電效應,將機械能轉換成電能,則電流在導電粒子產生的迴路中流動,由於導電迴路具有一定的電阻,所以電能又轉變成熱能耗散掉,從而起到減振的目的。
  3.
