The presented article deals about hybrid composite materials based on natural fibers and their mechanical testing. It contains test process of composite materials, which contain staple fibers and whole fibers of hemp, cotton, sisal and jute combined with carbon fabric. The objective of the thesis is to confirm or decline the ability of hybrid bio-composites usage in automotive industry following the testing results. Experimental part contains the methods of bio-composites test samples manufacturing and the testing, particularly tensile strength testing and impact test at a bending. The results of this part are statistically evaluated. |
