The shear web is manufactured by using a forming tool (78a, 78b) to define a flange-shaped cavity (84) at an end of a web member (70). A resin is injected (86) into the cavity (84) and cured to form a flange cast onto the web member. The forming tool (78a, 78b) is subsequently removed from the web member to provide a component having a load-bearing flange formed from a cured resin.
