Description
本发明涉及一种复合材料太阳能发电支架。
复合材料是一种混合物。在很多领域都发挥了很大的作用，代替了很多传统的材料。复合材料按其组成分为金属与金属复合材料、非金属与金属复合材料、非金属与非金属复合材料。按其结构特点又分为：1、纤维增强复合材料。将各种纤维增强体置于基体材料内复合而成。如纤维增强塑料、纤维增强金属等。2、夹层复合材料。由性质不同的表面材料和芯材组合而成。通常面材强度高、薄；芯材质轻、强度低，但具有一定刚度和厚度。分为实心夹层和蜂窝夹层两种。3、细粒复合材料。将硬质细粒均匀分布于基体中，如弥散强化合金、金属陶瓷等。4、混杂复合材料。由两种或两种以上增强相材料混杂于一种基体相材料中构成。与普通单增强相复合材料比，其冲击强度、疲劳强度和断裂韧性显著提高，并具有特殊的热膨胀性能。分为层内混杂、层间混杂、夹芯混杂、层内/层间混杂和超混杂复合材料。
复合材料中以纤维增强材料应用最广、用量最大。其特点是比重小、比强度和比模量大。例如碳纤维与环氧树脂复合的材料，其比强度和比模量均比钢和铝合金大数倍，还具有优良的化学稳定性、减摩耐磨、自润滑、耐热、耐疲劳、耐蠕变、消声、电绝缘等性能。石墨纤维与树脂复合可得到热膨胀系数几乎等于零的材料。纤维增强材料的另一个特点是各向异性，因此可按制件不同部位的强度要求设计纤维的排列。以碳纤维和碳化硅纤维增强的铝基复合材料，在500℃时仍能保持足够的强度和模量。碳化硅纤维与钛复合，不但钛的耐热性提高，且耐磨损，可用作发动机风扇叶片。碳化硅纤维与陶瓷复合，使用温度可达1500℃，比超合金涡轮叶片的使用温度(1100℃)
高得多。碳纤维增强碳、石墨纤维增强碳或石墨纤维增强石墨，构成耐烧蚀材料，已用于航天器、火箭导弹和原子能反应堆中。非金属基复合材料由于密度小，用于汽车和飞机可减轻重量、提高速度、节约能源。用碳纤维和玻璃纤维混合制成的复合材料片弹簧，其刚度和承载能力与重量大5倍多的钢片弹簧相当。
玻璃钢(FRP)亦称作GFRP，即纤维强化塑料，一般指用玻璃纤维增强不饱和聚脂、环氧树脂与酚醛树脂基体。以玻璃纤维或其制品作增强材料的增强塑料，称谓为玻璃纤维增强塑料，或称谓玻璃钢。由于所使用的树脂品种不同，因此有聚酯玻璃钢、环氧玻璃钢、酚醛玻璃钢之称。质轻而硬，不导电，机械强度高，回收利用少，耐腐蚀。可以代替钢材制造机器零件和汽车、船舶外壳等。
玻璃钢的优点是：轻质高强。相对密度在1.5～2.0之间，只有碳钢的1/4～1/5，可是拉伸强度却接近，甚至超过碳素钢，而比强度可以与高级合金钢相比。因此，在航空、火箭、宇宙飞行器、高压容器以及在其他需要减轻自重的制品应用中，都具有卓越成效。某些环氧FRP的拉伸、弯曲和压缩强度均能达到400Mpa以上。耐腐蚀。FRP是良好的耐腐材料，对大气、水和一般浓度的酸、碱、盐以及多种油类和溶剂都有较好的抵抗能力。已应用到化工防腐的各个方面，正在取代碳钢、不锈钢、木材、有色金属等。电性能好。是优良的绝缘材料，用来制造绝缘体。高频下仍能保护良好介电性。微波透过性良好，已广泛用于雷达天线罩。热性能良好。FRP热导率低，室温下为1.25～1.67kJ/(m·h·K)，只有金属的1/100～1/1000，是优良的绝热材料。在瞬时超高温情况下，是理想的热防护和耐烧蚀材料，能保护宇宙飞行器在2000℃以上承受高速气流的冲刷。可设计性好。(1)可以根据需要，灵活地设计出各种结构产品，来满足使用要求，可以使产品有很好的整体性。(2)可以充分选择材料来满足产品的性能，如：可以设计出耐腐的，耐瞬时高温的、产品某方向上有特别高强度的、介电性好的，等等。工艺性优良。(1)
可以根据产品的形状、技术要求、用途及数量来灵活地选择成型工艺。(2)工艺简单，可以一次成型，经济效果突出，尤其对形状复杂、不易成型的数量少的产品，更突出它的工艺优越性。
玻璃钢的缺点是：弹性模量低。FRP的弹性模量比木材大两倍，但比钢(E＝2.1E5)小10倍，因此在产品结构中常感到刚性不足，容易变形。可以做成薄壳结构、夹层结构，也可通过高模量纤维或者做加强筋等形式来弥补。长期耐温性差。一般FRP不能在高温下长期使用，通用聚酯FRP在50℃以上强度就明显下降，一般只在100℃以下使用；通用型环氧FRP在60℃以上，强度有明显下降。但可以选择耐高温树脂，使长期工作温度在200～300℃是可能的。老化现象。老化现象是塑料的共同缺陷，FRP也不例外，在紫外线、风沙雨雪、化学介质、机械应力等作用下容易导致性能下降。剪切强度低。层间剪切强度是靠树脂来承担的，所以很低。可以通过选择工艺、使用偶联剂等方法来提高层间粘结力，最主要的是在产品设计时，尽量避免使层间受剪。玻璃钢的生产方法基本上分两大类，即湿法接触型和干法加压成型。如按工艺特点来分，有手糊成型、层压成型、RTM法、挤拉法、模压成型、缠绕成型等。手糊成型又包括手糊法、袋压法、喷射法、湿糊低压法和无模手糊法。
复合材料在太阳能发电支架中的利用也逐渐广泛，中国专利公开了一种太阳能聚光热发电支架，包括扭矩框和悬臂支架，所述悬臂支架通过螺栓固定在扭矩框上，扭矩框由多个支杆通过螺栓连接形成，扭矩框的边角处设有端部支撑杆，悬臂支架由多个支杆通过螺栓连接形成，悬臂支架包括左支架和右支架，左支架和右支架通过横梁固连成一整体。
中国专利公开了一种太阳能板支架，属于太阳能发电领域，该支架设置在太阳能板下方，所述支架内的连接处为螺栓连接；本发明的技术方案中，取代现有技术的焊接，其优点是螺栓便于拆卸，根据需要可调节支架的高度，使之能够最大效率发挥太阳能板的作用。
