Sažetak
In previous researches, during bending strength determination of plywood reinforced with bi-directional carbon fibres (fibre quantity was 12 K, meaning 12000 filaments per tow), delamination was noticed in zone of force action, the phenomenon which is not present in ordinary plywood. It was assumed that it was probably caused by great difference between properties of the used materials. Hence it was presumed that the use of reinforcer with lower quantity of carbon fibres in tow would not decrease bending properties of reinforced plywood. Five layer plywood reinforced with impregnated carbon fibre cloth was produced to research whether a significant reduction of quantity of carbon fibres had influence on bending properties of reinforced plywood. The carbon fibres used in the experiment had 3000 filaments per tow (3K). In order to provide better understanding of the problem, models were developed and analysed by use of the Finite Element Method. The achieved results of research were compared to the results of testing non-reinforced plywood and plywood reinforced with 12 K quantity of carbon fibres used in previous researches.
