The paper presents the attempt to assess the failure progress of a stitched carbon fiber reinforced plastic (CFRP) laminate by means of simple analysis of the failure energy after static bending tests. A laminate reinforced with a carbon twill weave (2/2) fabric areal mass of 200 g/m2 in the form of 10 layer preforms was used for the tests.

Apr 04 2015 · A significant amount of technical lignins is produced in the pulp and paper industries. However most technical lignins are burned for thermal recycling and a few percent are used as materials such as lignosulfonate as a dispersant. Native lignin has a highly complex structure and is susceptible to structural variations depending on the pulping process thus hindering the effective
