Abstract (en)

[origin: WO8001176A1] Fiber materials, especially for use as reinforcing fiber element in composite materials based on organic and/or inorganic binders, are treated with metal oxide acylates, which facilitates the ability of the fibers to become defibrated and uniformly distributed in the final composite material. Cellulose fibers treated with e.g. aluminum oxide stearate or titanium oxide acylate do not swell with water and do not tend to comglomerate. During treatment with metal oxide acylates the fibers should be dry.
