試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。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。By compounding caco3 with pp, the effect of caco3 content, diameter and shape on the crystallization, dispersion morphology and properties of pp / caco3 composites was investigated. the results showed that addition of caco3 into pp decreased the apparent crystal size in perpendicular direction to the ( 110 ), ( 040 ) and ( 130 ) crystallographic planes of ppa crystal, and with similar uniform dispersion of caco3, the dominant factor influencing toughness is the diameter of caco3 particles, but not the decrease of pp crystal size. the toughening effectiveness of nano caco3 is obviously better than that of micron caco3
將caco _ 3與pp進行填充復合，研究了caco _ 3含量、粒徑及形狀對體系的結晶，分散形態及性能的影響，發現碳酸鈣的加入使聚丙烯晶型垂直於（ 110 ） 、 （ 040 ）和（ 130 ）晶面的表觀晶體尺寸減小，揭示了在分散均勻的情況下，影響材料韌性的主導因素不是晶粒尺寸的減小，而是碳酸鈣的粒徑，納米張玲：彈性體及無機剛性粒子增韌增強聚丙烯復合材料的研究碳酸鈣的增韌效果明顯優于微米碳酸鈣。The followings are carried out for ballistic composite with resin matrix to realize its double function of loading and bulletproof and meet various tactics technology demands in the paper 1. the resin and reinforcement for arms ballistic system are selected and ballistic properties for composites with different resin matrixs ( improved phenolic, polyethylene, rubber, bi - phenol - a, and biamaleimide ) and different fibers ( kevlar, glass, carbon and uhmwpe fiber ) are investigated, with the aim of maxwell model to explain the matrix match principle for ballistic composites
