Method
Composite Layup
Aerospace Engineering
Composite layup is the aerospace manufacturing process of building a structural part from layers of fiber-reinforced material, typically carbon fiber or fiberglass cloth pre-impregnated with resin, placed by hand or by automated fiber-placement machines onto a mold in a specified sequence of ply orientations. The stacked plies are then cured, usually in an autoclave under heat and pressure, to bond the resin into a solid laminate. The technique lets engineers tailor a part's strength and stiffness by direction, and it became central to modern aircraft manufacture as composite fuselage and wing structures, such as those on the Boeing 787 and Airbus A350, replaced a growing share of aluminum airframe components.
Facts
Core PrincipleThe layup process builds a composite part by placing resin-impregnated reinforcing fiber cloth onto a mold, using rollers and brushes to work the resin into the fibers and remove trapped air, before the stack of plies is cured into a solid laminate. 1 Connections

the resins are impregnated by hand into the reinforcing fibers. Rollers and brushes are used to incorporate the resin into the fibers and to remove air from the composite.
