Hybrid epoxy systems modified with Abies alba exudate: Cotton versus silk reinforcements
The mechanical behavior of hybrid composite materials was studied based on a matrix composed of 50 wt.% Abies alba exudate and 50 wt.% epoxy resin, reinforced with cotton and silk fabrics. Composite plates were manufactured using a hand lay-up technique with a 40/60 resin-to-reinforcement ratio. Mechanical characteriza...
