Abstract

Charge comportant de la farine de bois et un matériau pulvérulent de densité plus élevée, ladite charge permettant, ajoutée à au moins une résine synthétique, d'obtenir sous un volume réduit une pièce moulée d'un poids donné. Le matériau pulvérulent, d'une densité de l'ordre de 1, chimiquement neutre par rapport aux résines synthétiques employées, est par exemple constitué par du filler calcaire d'une granulométrie de 60 mu et est ajouté dans une proportion de 36 % à une farine de bois d'une granulométrie de 200 mu et d'une densité de l'ordre de 0,12. La charge peut être utilisée, mélangée à une résine phénolique, à la fabrication de pièces moulées.
