摘要: The invention relates to a process for treating a lignocellulosic material, preferably wood, comprising the following steps: (1) soaking of the material with organic fluid in order to dissolve at least 40% and at most 85%, in weight %, of the lignin of the material; (2) washing with organic fluid so as to discharge the dissolved lignin; (3) filling with a filling compound; and (4) finishing, so as to obtain a composite formed of a three-dimensional network of transformed filling compound incorporated into a cellulose and lignin network. The invention also relates to a composite structure able to be obtained in this way, and to any part comprising at least one such structure.

摘要: The invention relates to a process for treating a lignocellulosic material, e.g., wood, comprising the following steps: providing a lignocellulosic material; removing at least some but less than all lignin from the lignocellulosic material to yield a delignified structure; and densifying the delignified structure to yield the delignified, densified material, wherein the delignified, densified material is equal in size or is smaller in size relative to the lignocellulosic material provided; where densifying may include contacting said delignified structure, at least in part, with at least one fluid at a pressure greater than atmospheric pressure. The invention also relates to a composite structure able to be obtained in this way, and to any part comprising at least one such structure.
