22 may be lined with a composite or structural fabric 30 as shown in fig3 that is infused prior to adding the reinforcing material 26 material and spraying the foam leaving only the task of capping the cured shear web 20 with other composite material in order to form the shear web shape any structural fabric 30 in the mold may also be infused with resin after it is removed from the mold 20 on the least partially cured foam in addition to the female mold 22 shown in fig3 5 the molded and or reinforced shear web core my be implemented using a male mold 32 as shown in fig6 the male mold 32 generally conforms to the shape of the shear web core resin impregnated structural fabric 30 is loaded onto the outside of the male mold 32 in order to form the skin of the shear web 20 slots may be provided in the surface of the male mold 32 for helping to disperse resin in the structural fabric 30 once cured and removed from the mold the shear web skin can be filled with a liquid material such as an expanding foam like a closed cell structural foam and any reinforcing material 26 in a similar manner to that shown in fig3 and 4 the male mold 32 may also take the form of spacers or other structural material to which laminate sheets are applied resin impregnated structural fabric 30 is then applied to the top.
