Strength of Fibre Reinforced Plastic Products
Fibre reinforced plastic (FRP) products are composite materials made up of a polymer matrix and reinforcing fibres. The strength of these products depends on various factors, which are discussed below:
Fibre and Plastic
The strength of FRP products depends on both the fibre and plastic used in their manufacturing process. The properties of the fibres, such as their strength, stiffness, and orientation, affect the mechanical properties of the composite material. Similarly, the properties of the plastic, such as its toughness, stiffness, and ductility, also influence the strength of the product.
Anisotropic
FRP products are generally anisotropic, i.e., their mechanical properties vary with the direction of loading. This is because the fibres are oriented in a specific direction, which determines the strength of the product in that direction. Therefore, the strength of FRP products is dependent on the orientation of fibres.
Isotropic
However, in some cases, FRP products can be made isotropic by randomly orienting the fibres in all directions. This results in a uniform distribution of strength in all directions.
Correct Statements
Based on the above discussion, the correct statements regarding the strength of FRP products are:
- The strength of FRP products depends on both the fibre and plastic used in their manufacturing process.
- FRP products are generally anisotropic, i.e., their strength varies with the direction of loading.
Therefore, option D, i.e., 2 and 4, is the correct answer.
