As the blade length of a wind turbine rises, the specific length and stiffness of the blade must also increase. This difficulty can be solved by substituting carbon fibre for the frequently used glass fibre (GF). CF is stiffer, stronger, more fatigue-resistant, and less dense than steel, but it costs a lot more.
The hybridization of GF and CF, in which CF and GF are integrated into a single structure with CF inserted in key areas, has gotten a lot of interest.
Due to their anisotropy, low strain to failure, and differences in thermal expansion, efficient connecting of multiple fibre types is difficult, resulting in high residual thermal stresses.

Frequently Asked Questions
1. What are hybrid composites?
Hybrid composites are composites with two or more reinforcing fibers. Carbon-aramid reinforced epoxy (which combines strength and impact resistance) and glass-carbon reinforced epoxy is the most popular hybrid composites.
2. When should hybrid composites be used?
Commercial, industrial, aeronautical, maritime, and recreational constructions can all benefit from hybrid composites.
3. Fracture toughness of unidirectionalglass/carbon hybrid composites
In fracture mechanics, there are three types of fracture: mode I (tensile fracture), mode II (shear fracture), and mode III (out-of-plane tearing fracture)

Frequently Asked Questions
1. What is strain energy?
Strain energy is a type of potential energy stored by an object as a result of elastic deformation. When an object is deformed from its unstressed state, the external work done on it is transformed into (and considered equivalent to) the strain energy contained in it. It is measured in N-m or Joules.
