Abstract

L'invention concerne un composite absorbant présentant une âme réticulée et une strate fibreuse. L'âme et la strate sont formées solidaires et la strate est accolée à une surface extérieure de lame. Dans un mode de réalisation, le composite comprend des strates sur les surfaces extérieures opposées de l'âme. L'âme comprend une matrice fibreuse et une matière absorbante. La matrice fibreuse définit des vides et des passages entre les vides, lesquels sont répartis dans tout le composite. Une matière absorbante est située à l'intérieur de certains des vides. Lors d'une humidification, la matière absorbante située dans ces vides s'étend à l'intérieur du vide. L'invention concerne également des articles absorbants contenant le composite.
