Claims19
A composite material comprising a matrix having modified cellulose fibres and/or modified cellulosic fabric embedded therein, wherein the cellulose fibres and/or cellulosic fabric is modified with one or more hydrocarbon acids having a carbon number of at least about 6, wherein the one or more hydrocarbon acids include an acid selected from the group consisting of linseed acid, hempseed acid and combinations thereof, wherein the modification covalently links the one or more hydrocarbon acids to the cellulose fibres and/or cellulosic fabric.
A composite material comprising a matrix having modified cellulose fibres and/or modified cellulosic fabric embedded therein, wherein the cellulose fibres and/or cellulosic fabric is modified with one or more hydrocarbon acids having a carbon number of at least about 6,
- wherein the one or more hydrocarbon acids include an acid selected from the group consisting of linseed acid, rapeseed acid, soybean acid, hempseed acid, and combinations thereof,
- wherein the cellulosic fabric has a weight ranging from about 10 gsm to about 1000 gsm, and
- wherein the modification covalently links the one or more hydrocarbon acids to the cellulose fibres and/or cellulosic fabric.
A composite material comprising a matrix having modified cellulose fibres and/or modified cellulosic fabric embedded therein, wherein the cellulose fibres and/or cellulosic fabric is modified with one or more hydrocarbon acids having a carbon number of at least about 6,
- wherein the one or more hydrocarbon acids include an acid selected from the group consisting of linseed acid, rapeseed acid, soybean acid, hempseed acid, and combinations thereof, and
- wherein the cellulose fibres have an average diameter equal to or greater than about 1 μm, and
- wherein the modification covalently links the one or more hydrocarbon acids to the cellulose fibres and/or cellulosic fabric.
