4、降低成本，提高质量，节约能源，减少运输，保护耕地，保护环境和提高技术经济效益等为了达到此目的，必须从改善现有的建筑材料和发展新。型建筑材料方向着手。树脂基复合材料的出现，给了我们新的选择。从树脂基复合材料的建筑性能上分析，主要体现在：材料性能的可设计性树脂基复合材料的性能可根据使用要求进行设计，如要求耐水、。防腐、高强，可选用树脂基复合材料。由于树脂基复合材料的重量轻，制造方便，对于大型结构和形状复杂的建筑制品，能够一次成型制造，从而提高建筑结构的整体性。力学性能好。树脂基复合材料的力学性能可在很大范围内进行设计，Because of the different materials used,

5、 the difference of the laying direction of the reinforcing material can lead to great difference in performanceThe tensile strength of composites such as unidirectional glass fiber reinforced epoxy composites can reach above 1000MPa, and the tensile strength of the composites is higher than that of

6、steel (construction steel)The modulus of elasticity of the resin matrix composite can be up to the level of the building steel, but the density is better than that of the steel4 to 5 times smaller. What is more outstanding is that the resin matrix composite can be locally strengthened according to t

7、he force condition of the component in the manufacturing processThe utility model can improve the bearing capacity of the structure, save materials and reduce weight. Decorative good. The surface of the resin matrix composite is bright and clean and can be preparedA variety of bright colors, but als

8、o can produce different patterns and patterns, suitable for making all kinds of decorative boards, large relief and art, sculpture and so on.Light transmittance. Transparent glass fiber reinforced plastics of light transmittance of more than 85% (similar to glass), the biggest feature is not easy to

9、 break, can withstand the load. Be used forWhen building construction, the structure, enclosure and lighting can be integrated into three designs, which can simplify the daylighting design and reduce the cost of the project. The septumThermal property. Buildings can prevent temperature changes cause

10、d by heat conduction and heat convection, and provide people with good working and resting environment. General building materialsThe thermal insulation property of the material is poor, for example, the thermal conductivity of ordinary concrete is 1.5 - 2.1W (M = K), and the thermal conductivity of

11、 the red brick is0.81W (M. K), the thermal conductivity of resin based composite sandwich structure is 0.05 - 0.08W (M = K), l0 times smaller than ordinary red brick, better than mixingThe soil is 20 times smaller. The sound insulation. The effectiveness of sound insulation is one of the criteria fo

12、r evaluating the quality of buildings. But in the traditional material, the sound insulation effect is good67Page and 2VIP information Forestry Survey and design (Fujian) 2005 secondBuilding materials tend to be of larger density, poor heat insulation, and difficult to transport and install. Althoug

13、h the sound insulation properties of resin matrix composites are not ideal, they haveTo eliminate the vibration and sonic sonic propagation effect, after the sandwich structure specially designed, can achieve the dual effect of both noise and heat insulation. The electricCan. Glass fiber reinforced

14、plastic has good insulation performance, it is not affected by electromagnetic wave, and does not reflect radio waves. By design, it can be made in a wide frequency bandIt has a good microwave transmission performance and is especially beneficial for buildings that build radio communication systems,

15、 such as radar, radome and other machinesSuch room. The resistance to chemical corrosion. Glass fiber reinforced plastics have good anti microbial effects and the ability to resist acids, alkalis, organic solvents and sea water. EspeciallyApplicable to chemical, construction, underground and hydraul

16、ic construction projects. To water and water absorption. Glass fiber reinforced plastic has low moisture absorption and is impervious to waterWaterproofing, water supply and drainage works in construction.2 architectural applications of resin matrix compositesAs a new type of building material, resi

17、n matrix composite has a variety of good architectural properties as mentioned above and uses trees in the construction industryThe grease base composite material can reduce the weight of building and improve the use function of building, reform architectural design, speed up construction progress a
