【正文】 n of fossil resources, water and CO2 production.8. During the oxodegradation of carboxylic acid, molecules of alcohols, aldehydes and ketones degradable with low molar mass are produced by peroxidation initiated by heat or light .9. While most of the mercialized biopolymer materials are biodegradable, these are not fully postable in real posting conditions, which vary with temperature and relative humidity.Unit 161. 比如，多相金屬在微觀尺度上是復(fù)合材料。但一般意義上的復(fù)合材料是指通過鍵的作用使兩種或多種不同的材料結(jié)合在一起的材料。2. 最常見的是，復(fù)合材料有一個連續(xù)的叫基體的本體相，還有一個分散的非連續(xù)的叫增強(qiáng)相的相。3. 先進(jìn)材料采用了樹脂與纖維的復(fù)合材料，一般為碳/石墨，凱芙拉或玻璃纖維與環(huán)氧樹脂的復(fù)合材料。纖維具有高的硬度，而聚合物樹脂基體能保持復(fù)合材料的結(jié)構(gòu)。4. 如果復(fù)合材料設(shè)計和制備合理的話，復(fù)合材料就既具有增強(qiáng)相的強(qiáng)度又具有基體的韌性從而得到了性能的理想組合，這是任何一種組分單獨存在時所具備的性能。5. posite material reinforcement material Fiberglass matrix material Strengthening mechanism conventional material6. A posite is monly defined as a bination of two or more distinct materials, each of which retains its own distinctive properties, to create a new material with properties that cannot be achieved by any of the ponents acting alone.7. Carbonepoxy posties are two thirds the weight of aluminum, and two and a half times as stiff. Composites are resistant to fatigue damage and harsh enviroments, and are repairable.8. According to the conception of posite , reinforced plastics, metalmatrix posites, ceramicmatrix posites and concrete are posites.9. In fiberreinforced posites, the fiber is the primary loadbearing ponent. Fiberglass and carbon fiber posites are examples of fiberreinforced posites.Unit 171. 震蕩、撞擊或者重復(fù)的周期性應(yīng)力能導(dǎo)致兩層的界面處發(fā)生薄層分離，這種情況叫剝離。2.3. 事實上，工業(yè)材料既要質(zhì)輕又要牢固的要求是推動復(fù)合材料發(fā)展的主要動力。4. 提到飛機(jī)，值得銘記的是復(fù)合材料不像金屬（如鋁）那樣在壓力的作用下會完全解體。5. orthotropic thermoset Thermoplastic Young’s Modulus Mechanical property constants extreme enviroment6. In contrast, isotropic material ( for example, aluminuim or steel), in standard wrought forms, typically have the same stiffness regardless of the directional orientation of the applied forces and /or moments.7. The greatest advantage of posite materials is strength and stiffness bined with lightness.8. This makes them ideal for use in products thar are exposed to extreme enviroments such as boats, chemicalhandling equipments and spacecrafts.9. Composites will never totally replace tranditional materials like steel, but in many cased they are just what we need.Unit 181. 具有相分離的聚合物共混材料經(jīng)常出現(xiàn)納米尺度的相。2 在過去幾十年里研究的基于溶膠凝膠化學(xué)的有機(jī)無機(jī)納米復(fù)合材料已基本淡出納米復(fù)合材料的研究。3. 理解粒子的性質(zhì)隨著尺寸降低到納米級別而發(fā)生改變，這對于優(yōu)化所得到的納米復(fù)合材料很重要。4. 廉價石墨的生產(chǎn)尚未實現(xiàn)，石墨的廣泛使用嘔待石墨合成技術(shù)的突破。5. electrooptical property bactericidal propertyBlock copolymer interfacial phenomenaExfoliated graphene morphology control6. The field of nanotechnology is one of the most popular areas for current research and development in basically all technical discillines.7. Nanoscale is considered where the dimensions of the particle, platelet or fiber modification are in the range of 1～100nm.8. These improvements are key to future aircraft and wind energy turbine applications.9. Nanostructured surfaces have been noted to yield superhydrophobic character and exceptional adhesion.
