Twin matrix composites consists of fibre bundles impregnated by a hard matrix. These bundles are then embedded in a flexible polymer to increase the transverse failure strain of the laminae, but a tougher flexible matrix should also provide better impact resistance. In this thesis, a twin matrix composite is made using carbon pultrusions embedded in a vitrimer, and its behaviour under impact is tested using a quasi static indentation test and compared to a traditional unidirectional laminate. The twin matrix composite exhibits higher deflection, and a non destructive test using ultrasounds revealed lesser delamination area at the same energy and strain rate than the UD one.
