    Abstract: A method of forming a fibre reinforced polymer structure, comprises the steps of:- providing a first bundle of fibres arranged in an array and having a first fibre volume fraction (FVF); forming a node region in the bundle wherein a transverse dimension of the first bundle is increased and a second perpendicular dimension of the bundle is decreased so that the first FVF is maintained at an approximately constant value; providing a second bundle of fibres extending in angular relation to the first bundle, arranged in an array and having a second FVF; forming a node region in the second bundle wherein a transverse dimension of the second bundle is increased and a perpendicular dimension of the second bundle is decreased so that the second FVF is maintained at an approximately constant value; wherein the node region of the second bundle overlies the node region of the first bundle to form an assembly; infusing the assembly with a polymer resin; and curing the resin to form the structure.

    Abstract: A one-piece plastics material mesh structure (1), particularly a geogrid for use in geoengineering construction, is produced by stretching a plastics sheet starting material (20) formed with an array of holes (21). The mesh structure (1) comprises a plurality of generally parallel rib structures (2) extending longitudinally in a first direction parallel to the stretch direction (MD) and a plurality of generally parallel bar structures (3) extending in a second direction (TD) transverse to the rib structures (2). The rib structures (2) and said bar structures (3) are interconnected by junctions (5) at spaced locations along their respective lengths whereby the rib structures (2) are sub-divided along their length into alternating junctions (5) and rib segments (6) and the bar structures are sub-divided along their lengths by alternating bar segments (7) and junctions (5). In the mesh structure (1), (a) the rib structures (2) are such that the rib segments (6) are oriented in the first direction (MD) along their lengths and orientation in the first direction (MD) extends across the junctions (5) connecting two such oriented rib segments, and (b) the bar structures (3) are such that their overall stretch ratio in the second direction (TD) is a maximum of 1 and all locations along the length of the bar structures (3) have a maximum orientation of 1.5 in the second direction (TD).
