Impact response of bio-composite laminates made out of veneer and flax fabrics utilising different adhesives were experimentally studied in drop-weight tests. Response of materials behaviour has been compared by determination of impact force, energy absorption and deflection rate. Results showed that both adhesive and implementation of fabric in plywood can significantly enhance the performance of laminates in transverse direction. Impact properties of plywood made of polyethylene adhesive were increased 1.5 and up to 3 times with incorporation flax fabric. Results were compared to commercially available plywood produced accordingly to industrial standards made of phenol formaldehyde adhesive. During the 150J drop-weight impact tests all samples were punctured, showing local damage in upper veneer and much more extensive in bottom.
