COMPOSITE MATERIALS: GROWING APPLICATION FOR LIGHTWEIGHT PRODUCTS

 “From housing early civilizations to facilitating future inventions, composite materials have played an important role in human history. Corrosion resistance, design flexibility, longevity, light weight, and strength are only a few of the advantages of composites. Composites are used in a wide range of applications, including construction, medical applications, oil and gas, transportation, sports, aerospace, and many others. Without composite materials, certain applications, such as rocket ships, will most likely never get off the ground.”

Composites can be found in nature. Long cellulose fibres are kept together by a material called lignin in a piece of wood, making it a composite. Composite materials are created by combining two or more materials with distinct properties that do not dissolve or mix together. The composite's various materials work together to give it its distinct properties. For thousands of years, humans have used composite materials in a variety of applications. Early Egyptians and Mesopotamian settlers used a mixture of mud and straw to construct solid and stable structures around 1500 BC.

The fibre-reinforced polymers (FRP) industry arose from the growth and demand for composite materials. By 1945, over 7 million pounds of glass fibres had been used in a variety of items, often for military purposes. After the war, composite materials exploded in popularity, growing at a breakneck pace through the 1950s. Composite pioneers were attempting to break into new industries such as aerospace, manufacturing, and transportation. The benefits of FRP composites, especially their corrosion resistance, were quickly recognised by the public sector. One clear commodity that gained was boats. In 1946, the first composite commercial boat hull was published. In 1947, a complete composite car body was built and tested. The 1953 Chevrolet Corvette was born as a result of this.

The invention of the car ushered in a slew of modern moulding techniques, including compression moulding of bulk moulding compound (BMC) and sheet moulding compound (SMC) (SMC). For the automotive industry and other sectors, the two techniques have emerged as the prevailing form of moulding. Manufacturing techniques such as large-scale filament winding, pultrusion, and vacuum bag moulding were introduced in the early 1950s. The marine industry became the largest user of composite materials in the 1960s. The first carbon fibre was patented in 1961 and became commercially available some years later.

The composites industry is still developing today, with much of the expansion focused on renewable energy. Engineers can design to customise the composite based on the performant requirements, for example, making the composite sheet very strong in one direction by aligning the fibres that way, but weaker in another direction where strength is less necessary. Engineers may also choose properties including heat resistance, chemical resistance, and weathering resistance by selecting the right matrix content.

Natural fibres are being used as reinforcements in composites to replace synthetic fibres due to an increase in environmental consciousness and recognition of the need for sustainable growth in recent years.

VIRTUAL ASSISTANTS FOR IMPROVING CUSTOMER EXPERIENCE IN TELECOM INDUSTRY

 If you consider the customer satisfaction index, the telecom industry is probably one of the worst ranking industries. But that was only until 2019. By the end of 2020, together, the sector made sure to climb up the satisfaction rate. And guess what? They will be able to do that. However, it’s just the beginning.  The importance of customer experience is growing like never before. And one tool that’s helping telecom industries is the use of virtual assistants. Did you know that OTT platforms are eroding the revenues of telecom industries? With video-on-demand media, the consumers are trying to cut the cord even more eager than ever before.  However, things are changing. How? Let’s find out! Virtual Assistants Aiding in Better CX in Telecom: Decoding the Ways If the telecom industry upgrades its digital customer engagement scale, it can easily experience the upsides in terms of better engagement, services, resulting in boosting sales. However, telecom operators often don’t have the peo

E-HEALTH: THE BOOM IN DIGITAL HEALTH TO DUISRUPT LIFE SCIENCES AND MEDICAL COMMUNITY

  E-Health is an developing field in the intersection of public health, medical informatics, and business, mentioning to health services and data delivered or enhanced through the Internet and connected technologies. In the broader sense, the term characterizes a technical development and a state of mind, a way of thinking, an attitude, and a commitment for networked, global review, to recover health care locally, regionally, and globally by using information and communication technology. The 5 e's in "E-Health" Efficiency  - one of the promises of e-health is to increase efficiency in health care, thereby decreasing costs. One possible way of reducing costs would be by avoiding duplicative or unnecessary diagnostic or therapeutic interventions through enhanced communication possibilities between health care establishments and patient involvement. Enhancing quality  of care - increasing efficiency involves not only reducing costs but at the same time improving quality. E-

HYDROGEN STORAGE - A DISRUPTIVE TECHNOLOGY INNOVATION

  Excessive expectations have been met with disappointment in the past with hydrogen technologies. Nonetheless, a rising body of research suggests that these technologies are a viable choice for deep decarbonization of global energy systems, with recent cost and performance advances pointing to economic viability. The cost of producing, transporting, and storing hydrogen has decreased dramatically. This is complemented by an increase in clean technology regulations. As a result, we predict that hydrogen technology will gain traction, particularly in the transportation and alternative energy generation sectors. The transition to a sustainable energy economy needs an energy carrier capable of large-scale carbon-free energy transfers. Hydrogen is a sustainable energy carrier with the potential to benefit the whole energy sector. However, storing significant amounts of hydrogen is difficult. There are numerous obstacles to overcome in order to achieve a cost-effective hydrogen cycle. Hydro
