“…These fibers have a continuous fiber structure and strength natural woven and can reduce weight from 10% to 30% (which is the main thing in automotive design). Bakri et al [21], reported that coir reinforced polymer composites are potential using as an alternative material for making windmill blades. Natural fibers have different properties and characteristics from synthetic fibers, thus requiring different machining parameters.…”

One of the machining failures in composite materials is delamination damage. In this paper, machining parameters and delamination damage caused by the drilling process on ramie woven reinforced composite material with an unsaturated polyester matrix were investigated. The ramie woven used is ramie yarn type 12S/3. The machining process used 1.5 kW Pillar drills, where variations in the diameter of the "brad & spur" drill are 4 mm, 6 mm, 8 mm, and 10 mm, respectively. In this work, focuses on the influence of machining parameters like feeds rate and spindle speed. Holes quality was analyzed in terms of thrust force and delamination failure. From the results of this study, the thrust force value obtained at the time of drilling is very closely related to the delamination damage that happens. Delamination damage occurs on both sides of the holes drill.

To meet the increasing energy demand, renewable energy is considered the best option. Its patronage is being encouraged by both the research and industrial community. The main driving force for most renewable systems is solar energy. It is abundant and pollutant free compared to fossil products. Wind energy is also considered an abundant medium of energy generation and often goes hand in hand with solar energy. The last few decades have seen a sudden surge in wind energy compared to solar energy due to most wind energy systems being cost effective compared to solar energy. Wind turbines are often categorised as large or small depending on their application and energy generation output. Sustainable materials for construction of different parts of wind turbines are being encouraged to lower the cost of the system. The turbine blades and generators perform crucial roles in the overall operation of the turbines; hence, their material composition is very critical. Today, most turbine blades are made up of natural fiber-reinforced polymer (NFRP) as well as glass fiber-reinforced polymer (GFRP). Others are also made from wood and some metallic materials. Each of the materials introduced has specific characteristics that affect the system’s efficiency. This investigation explores the influence of these materials on turbine efficiency. Observations have shown that composites reinforced with nanomaterials have excellent mechanical characteristics. Carbon nanotubes have unique characteristics that may make them valuable in wind turbine blades in the future. It is possible to strengthen carbon nanotubes with various kinds of resins to get a variety of different characteristics. Similarly, the end-of-life treatment methods for composite materials is also presented.

Based on the increasing number of end of life wind turbine blades and the emphasis on resource conservation and environmental protection, more and more attention has been paid to the recycling and reuse of thermoset composite materials for wind turbine blades. This paper gives an overview of the main recycling technologies and reuse of recycled products. Current recycling technology still needs more work to move from laboratory stage to commercial production. Cheaper, less polluting, and more efficient recycling technologies are needed, along with remanufacturing technologies for high performance products can be obtained to expand the market for recycled materials. In addition, new environmentally friendly blade materials should be designed from the source, using natural fiber, modified thermosetting resin and recyclable thermoplastic resin, which make wind energy a truly clean energy.
