<p>The process for manufacturing a structural component e.g. luggage compartment shelf for an automobile vehicle, comprises supplying two skins (1, 2) on a thickness portion of an internal face (3) of a mold, placing the skins against a mold wall, injecting a rigid foam precursor mixture between the skins, expanding the foam, evacuating a reaction gas through a porous portion and a space, and removing the obtained component. The skins present a gas porosity and a partial porosity to foams thus allowing a partial penetration of the foams in the thickness portion. The process for manufacturing a structural component e.g. luggage compartment shelf for an automobile vehicle, comprises supplying two skins (1, 2) on a thickness portion of an internal face (3) of a mold, placing the skins against a mold wall, injecting a rigid foam precursor mixture between the skins, expanding the foam, evacuating a reaction gas through a porous portion and a space, and removing the obtained component. The skins present a gas porosity and a partial porosity to foams thus allowing a partial penetration of the foams in the thickness portion. The mold comprises a tub (4), a cover (5), and a space (6) between the tub and cover on a peripheral part. The skins are altered to a three-dimensional form before placing it in the mold, and have an opening. A functional organ is inserted in the opening before injecting the precursor mixture so that an anchorage part of the organ is molded by the foam. The organ has a disengaged part crossing the mold through a canal. Independent claims are included for: (1) a mold; and (2) a structural component.</p> |
