Zusammenfassung:	A lightweight concrete formwork panel has a wooden rectangular frame with perimeter members and inner ribs that define openings in the frame. A lightweight core material substantially fills the openings in the wooden frame. An outer skin substantially covers the frame. The outer skin has a layer of transversely oriented fibrous material and a layer of longitudinally oriented fibrous material. L'invention concerne un panneau de coffrage de béton, de poids léger, présentant un bâti rectangulaire en bois constitué d'éléments périphériques et de nervures intérieures qui définissent des ouvertures dans le bâti. Un matériau central de poids léger remplit sensiblement les ouvertures du bâti en bois. Une enveloppe extérieure recouvre sensiblement le bâti. L'enveloppe extérieure présente une couche de matériau fibreux orienté transversalement et une couche de matériau fibreux orienté longitudinalement.
