METHOD AND APPARATUS FOR MAKING A COMPOSITE STRUCTURE |
| 摘要 |
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. |

1. A method of forming a fibre reinforced polymer structure, comprising 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. |
