Resin system | |
In fiber-reinforced composite materials, resin is a matrix, which bonds fibers together to deliver stress between the fibers and protects them from self-abrasion in between fibers and external mechanical abrasion. |
Required characteristics for resin system | |
Mechanical properties | |
Impregnation and adhesion performance | |
Toughness | |
Heat resistance, etc. |
Epoxy resin |
It is a representative thermosetting resin that is widely used in aerospace applications and it is a polymer with 2 or more epoxy groups per molecule. These epoxy compounds are used as thermosetting resin by mixing with catalysts for ring-opening polymerization or curing agents. It has an advantage of easy and diverse adjustment of curing temperature or physical properties of the cured product by combination with epoxy resin, catalyst, and curing agent. |
Phenolic resin |
It is a representative thermosetting resin that is widely used in aerospace applications and it is a polymer with 2 or more epoxy groups per molecule. These epoxy compounds are used as thermosetting resin by mixing with catalysts for ring-opening polymerization or curing agents. It has an advantage of easy and diverse adjustment of curing temperature or physical properties of the cured product by combination with epoxy resin, catalyst, and curing agent. |
