而高強混凝土又有其自身缺陷，主要是:強度越高，脆性越大;摻入硅灰量大的高強混凝土，後期增長減小;由於高強混凝土自收縮大，因而變形性能也隨強度等級的提高而變得嚴重。Products function : put our “ sun shine ” brand carbon steel fiber evenly seep into concrete to form steel fiber reinforced concrete and it can decrease the thickness of reinforced concrete by half, it not only shorten the project time, save the material and manpower expense, bring distinct economic benefit, but also increase the performance of crack resistance, percussion resistance, tensile strength, bend resistance. scosspr resostamce amd wear resistance of the reinforced base materials. if the weight ratio of 2 % steel fiber seep into the concrete, it can solve the brittleness problem of the concrete, in the condition of 60 % ralative air humidity, after 21days air - dry, even 520 days air - dry, it ' s difficult to find any crack by eyesight, the bend resistance for the steel fiber concrete is 140 times stronger than the concrete without steel fiber, the capability of impact resistance increase 10 times
產品功能：將本公司「雙興」牌碳鋼纖維系列產品均勻地摻入混凝土中，形成鋼纖維增強混凝土，可使工程中鋼筋混凝土的施工厚度降低一半，不僅縮短了施工工期，節省了材料和人工費用，帶來顯著的經濟效益，且增強了基體的抗裂、抗沖擊、抗彎、抗剪、耐磨擦等性能，如摻入本公司2 %鋼纖維的混凝土，不僅解決了混凝土的脆性問題，在空氣相對濕度60 %的條件下風干21天後，甚至在風干520天，肉眼很難發現裂縫，摻入鋼纖維后的增強混凝土比不摻鋼纖維的混凝土抗彎強度提高140倍，耐沖擊荷載提高10倍。The questions the researcher concerned are which system will be chosen and how to obtain the good lithium ionic conductor materials, which is the basic departure of the paper. the addition of second phase in composite can change the interface structure and the conduction mechanism, improve the matrix conductivity and other function such as the sintering, crisping and so on, so the research of composites are an interesting field of the ionic conductors. the synthesis of lithium ionic conductor is often by solid state reaction, but this method needs high temperature and leads to the volatility of lithium which not only causes the drift of the compounds but gets the no well - distributed materials
研究者所關注的問題是選擇新的體系進行研究，以期得到性能更好的鋰離子導體材料，這也正是本論文的基本出發點；復合離子導體中第二相的加入改善了基質的界面結構和導電機制，不僅可以提高基質材料的電導率，還可以在一定程度上改善材料的其它性能，如燒結性能、脆性和機械強度等。因此復合材料的研究是離子導體一個有廣闊前景的發展方向；合成鋰離子導體，特別是成分復雜的體系以傳統的固相合成法為主，但這種方法需要較高的溫度，容易引起鋰的揮發，從而造成產物組成的偏移，而且不易得到顯微結構均勻的材料。Three - dimensionally braided structural composites have distinct structure that is fully integrated, continuously spatial fiber - network impregnated with ductile material. the new innovative materials have not plies as conventional composites have, and put an end once and all to low interlaminar strength showing in laminate materials. because of their enhanced stiffness and strength in the thickness direction, near - net - shape design and manufacturing, superior damage tolerance and specified aerospace function, the braided composites are gaining more and more attention of industry and academia

結果表明， kdp晶體材料的力學特性如彈性模量、剪切模量、硬度等具有強烈的各向異性特徵，這種各向異性特徵是單晶脆性材料超精密切削后產生明暗相間扇形分佈的根源，是影響加工表面質量的重要因素。It was found that the cracks can penetrate the interphase and the fiber rapidly when the interphase is thin, which causes the low flexural strength and fracture toughness, as well as the composites " brittle fracture. while the interphase is thick, multiple toughening mechanisms such as the crack deflection and matrix cracking can be activated, which cause the composites " flexural strength and fracture toughness is high and the composites " non - brittle fracture
當界面相較薄時，基體裂紋能夠迅速穿過界面相和纖維，復合材料具有較低的彎曲強度和斷裂韌性，表現為脆性斷裂模式；當界面相較厚時，復合材料能產生裂紋偏轉、基體開裂等多種增韌方式，具有較高的彎曲強度和斷裂韌性，呈韌性斷裂模式。After pretorsion the successor tensile yield limit and strength limit both improved very highly, but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17, when the pretorsional capacity was greater than17 ( prestrain value was 81. 19 % of total strain ), the successor strength limit rapid failed and approached the yield limit. this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen. when the specimen was operated by tension - torsion action, the yield limit had very large improved, but the strength limit changed very little. furthermore, the trend of the increase of the strength limit was suspended till the pretension capacity reached 0. 25 ( prestrain value was 66. 93 % of total strain )
A3鋼試件在預扭轉后，后繼拉伸屈服極限和強度極限均有很大提高，但強度極限的增大趨勢到預扭轉量為17為止，預扭轉量大於17 （預應變值為總應變的81 . 19 ）后強度極限迅速下降，與其屈服極限接近，這說明a3鋼試件經預扭轉強化后逐漸由塑性轉化為脆性。該預應變值為a3鋼試件的韌脆轉變點。 a3鋼試件在拉伸-扭轉作用下，屈服極限有很大提高，但強度極限沒有多大改變，而且，屈服極限的增大趨勢到預拉伸量為0 . 25應變（預應變量為總應變量的66 . 93 ）后就不再增加。The results showed that the fracture of the tooth - razor was brittle fracture, the material quality was normal, the main fracture reson was that the carbide in the microstructure of the tooth - razor was distributed as reticulation, the brittleness of the razor was increased and the toughness was decreased, so the tooth of the razor was broken by external force when it was working
結果表明，該剃齒刀的斷齒屬于脆性斷裂，主要是顯微組織中的碳化物分佈不均勻（呈網狀分佈） ，使刀具的脆性增大而強度、韌性下降，導致刀具在使用過程中由於外力的作用發生斷齒。The result of macro - quality experiments show : mineral admixtures markedly slow the hydrating velocity of cement slurry, decrease and delay the hydrating max - temperature, in which steel slag is more effective ; expansive agents compensate concrete shrinkage, enhance the concrete dense degree, strengthen the interfacial layer between fiber and cement matrix and improve the physical mechanics qualities of acic ; minimal admixtures markedly improve the concrete workability property, increase the concrete later intensity & density and the capability of anti - chemical attack and anti - permeability ; hybrid fiber reinforces the toughness of obviously acic by the means of anti - cracking effect of fiber with different sizes and different properties in the corresponding construction levels
