摘要： The invention relates to a process for manufacturing composite material which contains fiber based and polymer based material, wherein the manufacture includes a preliminary treatment process to form a raw stock mixture. According to the invention, the preliminary treatment process includes a hot-cold mixing device which comprises at least a heating stage, and that raw stock, which contains lignin-free material, and a coupling agent are fed to the mixing device to form the raw stock mixture, and adhesion between fiber based and polymer based substances of the raw stock is ameliorated by the coupling agent.

摘要： The invention relates to a method and an apparatus for controlling the quality in the manufacture of composite material which contains fiber based and polymer based material, wherein the manufacture includes a mixing process (1) to form agglomerates from a raw stock mixture. According to the invention, a combination of variables in the mixing process is observed, wherein the variables are selected from the group of moment, current consumption, time, sound, temperature and their combinations, and the mixing process as well as the quality of the agglomerates to be formed is controlled based on the acquired observations (6, 7).
