Method for manufacturing an aerogel-containing composite, said method comprising the steps of: providing fibers, at least some of which are first fibers, such as mineral fibers, polymer fibers, cellulose fibers, or other types of fibers, in an amount of from 3 to 80 wt % of the total weight of starting materials, providing an aerogel particulate material in an amount of from 10 to 75 wt % of the total weight of starting materials, providing a binder in an amount of from 1 to 30 wt % of the total weight of starting materials, suspending the fibers in a primary air flow and suspending the aerogel particulate material in the primary air flow, thereby mixing the suspended aerogel particulate material with the suspended fibers, mixing the binder with the fibers and/or aerogel particulate material before, during or after mixing of the fibers with the aerogel particulate material, collecting the mixture of fibers, aerogel particulate material and binder and pressing and curing the mixture to provide a consolidated composite with a density of from 120 kg/m.sup.3 to 800 kg/m.sup.3. With this method homogeneous composites can be produced.

A production method of pseudo-wood and pseudo-stone furniture or ornament material with natural grains has a characteristic in that, the magnesia, the magnesium chloride, the water and the glass fiber are used to function as the primary staple. Then, a determined amount of modifier, sawdust powder and talcum powder is added into the primary staple. Then, the mold and the framework are operated according to the determined steps. Then, the primary staple is shaped. Then, the primary staple performs an oxidation process to form the product. Thus, the product is directly manufactured by the mold, without needing multiple and complicated working steps.

A method for producing an inorganic silica gel fiber or aerogel fiber, comprising the following steps: a) extrusion of a gel, in particular a hydrogel or alcogel, by means of a spinneret directly into a coagulation bath to form at least one filament, b) stretching of the filament in the coagulation bath, c) regeneration of the filament by extraction from the coagulation bath, and d) supercritical drying or freeze drying in order to convert the filament into a silica fiber, in particular an aerogel fiber.
