The present invention relates to a fibre composite material W of increased translucency and/or mechanical strength, comprising a copolymer C encompassing monomers A-1, where A-1 form covalent bonds with functional groups B-1 on the surface of fibres B embedded in the fibre composite material W, and this fibre composite material W has greater translucency and/or mechanical strength than a fibre composite material Win which the copolymer C contains no A-1. The present invention further embraces a method for producing a fibre composite material W of increased translucency and/or mechanical strength.

A structural column comprises an inner sleeve comprising a first non-glass material, at least one sheet comprising bulk glass, and an outer sleeve comprising a second non-glass material. The inner sleeve has an outer surface and an inner surface defining a hollow interior of the structural column. An inner surface of each sheet is adjacent to at least a portion of the outer surface of the inner sleeve. The outer sleeve has an inner surface that is attached to at least a portion of an outer surface of each sheet, and the inner surface of the outer sleeve is attached to at least a portion of the outer surface of the inner sleeve. The inner sleeve and the outer sleeve can have a rectangular shape in cross-section. The bulk glass can comprise soda lime glass, and the first non-glass material and the second non-glass material can comprise high-density polyethylene.

A method of reducing the formaldehyde emission of a mineral fiber product bonded with a urea-modified phenol-formaldehyde resol resin-type binder comprises adding dextrose to the binder composition during and/or after preparation of the binder composition but before curing of the binder composition applied to the mineral fibers.
