MaezioTM composites make the product lighter and stronger
Fiber reinforced composites offer a variety of advantages, they are lightweight, metal-hard, corrosion-resistant, low maintenance requirements, higher design freedom, and excellent mechanical properties. With increasingly sophisticated production techniques, with aluminum Compared with traditional materials such as steel, wood or concrete, the advantages of composite materials in terms of cost-effectiveness and production scale are gradually emerging. Fiber composite materials can not only meet the growing demand for strong and lightweight materials, but also resources and energy. Economical materials.
German material manufacturer Covestro is at the forefront of composite technology innovation, providing a wide range of solutions for the renewable energy, construction, sportswear and electronics industries. At the 24th China International Composites Industry Technology Exhibition, Covestro demonstrated its rich composite materials solutions to shape the future of energy saving and environmental protection (Booth A1210 in Hall 1 of Shanghai World Expo Exhibition Hall).
'Sustainability is the main source of our innovation and one of the core elements of our overall business strategy. 'Costron Asia Pacific Innovation Leader, Costron Polymer Research and Development Center, Dr. Schmaco (Dr. Michael Schmidt) said, 'This means that we want to benefit the society through our products and technologies, improve people's quality of life while reducing environmental impact. Our composite solutions can meet these needs. Compared with traditional materials Innovative lightweight materials and their own production processes are more sustainable. Our research and development also focuses on areas such as construction, renewable energy and transportation.
Polyurethane resin makes wind power more efficient
In the case of wind power, a renewable energy source, the longer the turbine blades, the greater the amount of power generated. Therefore, the industry is continually trying to make longer blades, and the potential remains to be fully explored. However, longer blades are also designed and Manufacturing brings new challenges. This is where Covestro's solutions come in: Using Baydur® polyurethane resin, vacuum infusion technology makes it possible to make longer, more stable and efficient turbine blades.
The process and materials offer a number of advantages. Compared to conventional epoxy resins, polyurethane resins can produce lighter and stronger blades and give them better mechanical properties and fatigue resistance. In addition, due to the faster perfusion of polyurethane resins Without the need for post-cure, the production time of the blade can be greatly shortened. This is very important for the wind power industry, because the wind power industry is currently facing great challenges in improving production efficiency due to limited materials and technology. Covestro is constantly relying on its polyurethane solution. Crossing the limit, bringing competitive advantages to wind turbine blade manufacturers.
Polyurethane composites for renewable energy and energy saving solutions
Covestro is also actively developing pultrusion technology to produce fiber reinforced materials by mixing polyurethane resin with fiber. This technology developed by Covestro can significantly improve productivity, production process and product quality.
Compared with resins such as epoxy resin or vinyl resin, Covestro polyurethane resin has obvious advantages. Polyurethane resin has the advantages of low viscosity, good fiber wettability and strong reactivity, which can improve processing speed and reduce production cost. At this year's China International Composites Exhibition, Covestro exhibited two major polyurethane systems related to the technology: Baydur PUL® and DesmocompTM.
Baydur PUL®It can be used to manufacture durable parts with excellent thermal insulation properties. The system is very suitable for the manufacture of insulated window frames. This application is especially important for the Chinese construction industry. The energy consumption is mainly from windows, so China housing and The Ministry of Urban and Rural Construction clearly proposed the relevant standards for energy-saving doors and windows in its '12th Five-Year Plan. The windows made with Baydur PUL® are more insulated. The material not only has low thermal conductivity, but also has good wind pressure resistance. Performance, sound insulation and fire resistance, while improving energy efficiency and improving living comfort.
DesmocompTMIt is a matrix material system made of aliphatic polyurethane. It has good mechanical properties, excellent UV resistance, chemical resistance and weather resistance. It has high processing cost performance, long pot life and fast curing. Therefore, no coating is required. These characteristics make it an ideal choice for outdoor applications such as solar panels. At China International Composites Exhibition, Covestro will exhibit insulated frame solar modules based on this material, and non-metallic composites will increase resistance. PID (induced potential difference attenuation) performance, UV resistance, acid and alkali resistance, no need to ground. Last year, DesmocompTM won the 'JEC Innovation Award' at the JEC Composites Exhibition in Paris, the largest composites trade show in Europe.
MaezioTM new composites meet global demand
Covestro has developed a new technology for the efficient production of lightweight, sturdy and aesthetically pleasing continuous fiber reinforced thermoplastic composites (CFRTP). Recently, the company introduced a new brand name MaezioTM for CFRTP. The material is as strong as metal. , but light weight, free to form, can be recycled after the end of the product life cycle. The first products made of this material include home appliances, laptop casings and sports soles. For example, Covestro provides the Chinese Internet sports brand BMI. This material produces lightweight and sturdy marathon running shoes. Some MaezioTM applications are also on display at the China International Composites Exhibition.
In order to meet the huge market potential, Covestro has invested tens of millions of euros to build the first large plant in Markt Bibart, Germany, for the production of this new material. Here, Covestro uses these materials. Production of composite unidirectional tapes and sheets, which are then supplied to customers for further processing. Due to the lack of cost-effective and scalable production processes, further expansion of advanced composite materials has been hampered, and Covestro has broken through the commercial production of MaezioTM. This obstacle. Shortly after the factory was put into production, Covestro began selling this material online at its official flagship store in Alibaba, 1688, covestrochina.1688.com.
