Abstract
A composite material comprises of at least first and second layers, each comprising a polymeric matrix material and wound tows for reinforcement. The tows are wound in opposite directions in each of the first and second layers such that overlapping tows form crossover regions. The wound tows in the second layer are arranged such that the crossover regions are formed to be laterally offset from the crossover regions in the first layer.

A composite material comprising at least first and second layers each comprising a polymeric matrix material and wound tows for reinforcement, wherein the tows are wound in opposite directions in each of the first and second layers such that overlapping tows form crossover regions, wherein the wound tows in the second layer are arranged such that the crossover regions are formed to be laterally offset from the crossover regions in the first layer.
A method of manufacturing a composite material comprising at least first and second layers each comprising a polymeric matrix material and wound tows for reinforcement, the method comprising:
- winding the tows within each layer in opposite directions such that overlapping tows form a crossover region;
- and
- arranging the wound tows in the second layer such that the crossover regions are formed to be laterally offset from the crossover regions in the first layer.
