以绿色的方式工作是一个小时的需要，因为随着变暖，正面临许多挑战。TriovisionCompositeTechnologies是一家总部位于印度的公司，在工程、模具、原型制造和制造方面具有核心竞争力，它一直处于先进复合材料的前沿，它与Lush Motors和Winlet密切合作解决这些问题。结合Lush汽车的智能城市多功能车，风车的垂直轴风力发电机充电站和Triovision的复合知识，这个项目是无法完成的。
智能城市多用途车
茂盛汽车公司是一家总部位于印度的汽车公司，专注于绿色能源汽车的开发。使用两轮车在城市通勤的人们面临着诸如恶劣的环境、污染和健康问题，以及由于交通拥堵而产生的不适当的座位问题。为了满足日益增长的汽车需求，专门针对城市的通勤，该公司提出了三轮车和两座电动汽车的概念。独特的设计解决了这些问题，因为车辆是紧凑的，可以运行在任何交通，是完全封闭与天气保护，并具有先进的功能，如触摸屏，应用程序控制和手指扫描选项。对于传统的金属方法来说，设计是复杂的，复合材料在迅速将概念转化为运行模型方面起着重要作用。所有的车辆部件都是从上半身、地板、仪表板、侧后视镜和座椅开始由复合材料制成的。该机构使用的环氧树脂系统与纳米基础的添加剂，提供优异的性能，如减轻重量，高强度和良好的火灾和烟雾性能。减轻重量在汽车部门是必不可少的，以实现燃料效率，并反过来，大大降低运行成本。
TrioVision在设计、电子和软件开发的各个方面设计了这个产品，并生产了一个正在运行的原型，现在可以进行系列制造了。采用树脂转移成型工艺，两边均有良好的光洁度。由于该公司采用了模具内加热概念的创新分离工具，汽车的主体，这是一个具有挑战性的部件，容易制造，为高吞吐量的连续制造铺平了道路。传统填料也是一个挑战性的问题，在填充过程中，由于粘度的考虑，但该公司的填料系统在强度和火灾和烟雾性能方面取得了很好的效果。复合材料的使用极大地提高了汽车内的整体空间包络，而传统的方法是缩小内壳与外壳之间的间隙，以减少整体传热。该车辆也有一个独特的门机制，其中门是旋转在一个枢轴点，以提供好的优势，城市通勤时，车辆停在紧凑型空间。这是只有通过使用工程复合材料，因为门的重量是重要的，因为整个重量必须通过一个非中心点，其中一个巨大的负荷施加在电机上，试图旋转。由于复合材料的使用，这种作用是迅速而精确的。
“当这辆车终于站在我们面前时，我们简直不敢相信它和我们想到的概念是一样的。”Lush的席执行官说。
混合电力系统
温得乐是一家基于美国的能源技术和解决方案公司，主要致力于无线电信、wi-fi网状网络、电动汽车充电站、安全和监视、住宅和商业及其他分布式混合动力解决方案市场的低千瓦/分散可再生能源发电系统。该公司的业务仅包括与其混合动力系统解决方案的开发和商业化直接相关的活动和相关产品，如集成的PowerTower?，以及作为可再生网格?解决方案一部分的电动汽车充电站和wi-fi网状网络在内的hps和智能和动态能源寻址系统(IDEA?)的各种实现，以及作为微型电网能源解决方案的骨干。风带公司正与TrioVision合作，将其垂直轴风力涡轮机(VAWT)商业化并进一步发展，其基础是专有的Savonius拖曳驱动的风带?机翼系统。
VAWT的主要要求是能够在低风速下运行。这只有通过使用工程复合材料来减轻重量和增加强度才有可能。该VAWT独特的设计，使它非常有效地捕获能源在低风速和产生良好的输出。该刀片是使用树脂转移模塑与环氧树脂为基础的系统，以及在模内加热系统，可以支持串行制造。减轻重量是一个具有挑战性的设计方面，因为涡轮机可以暴露在沙尘暴和台风。采用TrioVision公司的纳米填充技术，其材料性能较差。整体减重的叶片重量对设计有很大的影响，给出了降低机组整体结构的可能性。温得乐HPS的一些应用包括汽车、农业、手机塔、微型电网、wi-fi网络、住宅和商业建筑、安全和监视市场。
电动汽车风车充电站
电动汽车工业目前面临的主要挑战是广泛使用它们所需的基础设施。风车独特的混合动力系统目前正在解决这些问题，以提供100%的可再生充电站给Lush汽车SUMV。这些充电站可以放置在任何地方，甚至在偏远的地方，这促进了电动汽车的使用，不仅在城市通勤，而且在城市以外的旅行。这将彻底改变汽车部门的运作方式，终所有加油站、超市停车场、公司办公室或私人住宅都可以转换为充电站。
复合材料的使用正在迅速增长，而许多部门正在试图改变他们的思维方式，以利用这些材料可以提供的关键利益。在这两个项目中使用它们(用于SUMV的Lush Motors和用于VAWM的风带)极大地受益于终产品。

The future of transportation is all set to be green, which means various alternatives need to be investigated to replac traditional gasoline vehicles. Another challenge is to make such alternatives lighter with improved strength for better efficiency, and at the same time, being able to mass produce them to meet the demand. The current industrial trends converge towards the development of electric vehicles, but proper infrastructure to charge the vehicles is just as important. TrioVision Composite Technologies, along with its partner companies Lush Motors and Windstrip, have come forward with an excellent solution using advanced composites to manufacture an electric vehicle and a vertical-axis wind turbine for a charging station.
Working in a green way is the need of the hour as the world is facing many challenges with global warming. TrioVision Composite Technologies, an Indian-based company with core competences in engineering, tooling, prototyping and manufacturing and which has been at the forefront of advanced composites, worked closely with Lush Motors and Windstrip to address these issues. Combining Lush Motors’ smart urban utility vehicle, Windstrip’s vertical-axis wind turbine charging station and Triovision’s composites knowledge, the project couldn’t be more accomplished.
Smart urban utility vehicle
Fig. 1- Smart urban utility vehicle by Lush Motors
Lush Motors is an Indian-based automotive company that focuses on the development of green-energy vehicles. People using two-wheelers for city commuting face challenges such as a harsh environment, pollution and health concerns with improper seating due to traffic congestions. To address the growing demand for vehicles specifically targeting city-based commuting, the company came up with the concept of a three-wheeler and two-seater electric vehicle. The unique design addresses these issues as the vehicle is compact in size and can run across any traffic, is totally enclosed with weather protection and has advanced features like a touch screen, app control and finger scanning options. The design was complex for a traditional metal approach and composites played a major role in quickly turning out the concept into a running model. All the vehicle parts are made of composites starting from the upper body, floor, dash, side mirrors and seats. The body uses an epoxy resin system with nano-based additives that provides excellent properties like reduced weight, high strength and good fire and smoke properties. Weight reduction is essential in the automotive segment to achieve fuel efficiency and, in turn, significantly reduce running costs.
TrioVision engineered this product in all aspects of design, electronics and software development and produced a running prototype that is now ready for serial manufacturing. The resin transfer moulding process was used, offering good finish on both sides. With the company’s innovative split tooling using an in-mould heating concept, the main body of the vehicle, which was a challenging component, was manufactured easily, paving the way for serial manufacturing with a high throughput. Traditional fillers were also a challenging issue during the filling process due to viscosity concerns, but the company’s filler system gave good results in terms of strength along with fire and smoke properties. The use of composites helped tremendously in increasing the overall space envelope inside the car, wheras the traditional approach was addressed with a reduced gap between the inner and outer shell to reduce the overall heat transfer. The vehicle also has a unique door mechanism wher the door is swivelled up across a pivot point to offer the best advantage of city commuting when the vehicle is parked in tight spaces. This was only possible through the use of engineered composites as the door weight is of utmost importance since the entire weight must swivel across an off-centric point wher an enormous load is applied on the motor that is trying to rotate. Thanks to the use of composite materials, the action is swift and precise.
“When the vehicle finally stood in front of us, we couldn’t believe our eyes that it was the same as the concept we thought of”, said Lush’s CEO.
Hybrid power system

Windstrip is a US-based energy technology and solutions company primarily focused on low-kilowatt/decentralized renewable energy generation systems for wireless telecommunications, wi-fi mesh networks, electrical vehicle charging stations, security and surveillance, residential and commercial and other distributed hybrid power solutions markets. The company’s operations solely consist of activities directly related to the development and commercialization of its hybrid power system (HPS) solution and related products, such as the integrated PowerTower?, and various implementations of the HPS and Intelligent & Dynamic Energy Addressing system (IDEAs?), including electric vehicle charging stations and wi-fi mesh networks, as part of the Renewable Mesh? solution, and as the backbone in micro-grid energy solutions. Windstrip is working with TrioVision to commercialize and further develop its vertical-axis wind turbine (VAWT) based on the proprietary Savonius drag-driven Windstrip? wing system.
The main requirement for the VAWT is to be able to run at low wind speeds. This was only possible through the use of engineered composite materials to reduce weight and increase strength. The VAWT’s unique design makes it very efficient to capture energy at low wind speeds and generate good output. The blades are manufactured using resin transfer moulding with an epoxy-based system along with an in-mould heating system that can support serial manufacturing. Weight reduction was a challenging design aspect as the turbine can be exposed to sand storms and typhoons. Its low suitable material using TrioVision’s nano-filler technology. The overall reduced blade weight greatly influenced the design by giving the possibility to reduce the unit’s overall structure. Some of the applications for Windstrip’s HPS include automotive, agriculture, cell towers, micro grids, wi-fi mesh networks, residential & commercial buildings, security and surveillance markets.
Windstrip charging stations for EVs
The main challenge currently faced in the electric vehicle industry is the infrastructure required to use them widely. Windstrip’s unique hybrid power system is currently addressing these issues to provide 100% renewable charging stations to Lush Motors SUMV. These charging stations can be placed anywher even at remote locations, which promotes the usage of electric vehicles in not just city commuting but also to travel beyond cities. This will totally change the way the automotive segment operates, and eventually all gasoline stations, supermarket parking lots, corporate offices or private residences could convert to charging stations.
The use of composites is growing rapidly while many segments are trying to change their way of thinking to utilize the key benefits these materials can offer. Using them in both projects (Lush Motors for SUMV and Windstrip for VAWM) tremendously benefitted the end-product.
