Shear web

The upright laminate member joining the spar caps inside a wind turbine blade or similar beam-like structure, transferring shear between them so the assembly behaves as an I-beam. Shear webs are commonly sandwich panels bonded in place with structural adhesive.

Spar cap

The main unidirectional load-bearing element running along the length of a wind turbine blade or wing spar, carrying the principal bending loads. Spar caps are typically thick stacks of unidirectional glass or carbon laminate, or pre-cured pultruded planks bonded into the structure.

Sandwich structure

A composite construction in which two thin, stiff skins are bonded to a thick, lightweight core such as foam, honeycomb or balsa. Separating the skins raises bending stiffness dramatically for very little added weight.

Structural adhesive

An adhesive designed to carry significant service loads as part of an engineered joint, transferring stress between substrates over the whole bonded area rather than at discrete fasteners. Epoxies, polyurethanes and methacrylates are the main chemistries, used in applications from aircraft assemblies to wind turbine blade bonding.
