Abstract
A method of manufacturing a moulded article from first and second moulding compounds includes attaching a first moulding component to a carrier tool, placing the carrier tool and the attached first moulding component in a mould, applying a first moulding process, removing the carrier tool, placing a second moulding component in the mould, and applying a second moulding process to shape the first and second moulding components and bond the first moulding component to the second moulding component. A moulded article is also disclosed.
Claims24
A method of manufacturing a moulded article from first and second moulding compounds, wherein:
- the first moulding compound comprises a first polymer and a first fibre reinforcing material embedded within the first polymer, wherein the first fibre reinforcing material is a directional fibre reinforcing material that includes a plurality of reinforcing fibres that extend preferentially in at least one primary reinforcement direction within the first moulding compound, and
- the second moulding compound comprises a second polymer and a second fibre reinforcing material embedded within the second polymer, wherein the second fibre reinforcing material is a non-directional fibre reinforcing material that includes a plurality of reinforcing fibres that extend in multiple directions within the second moulding compound, the method comprising:
- attaching a first moulding component to a carrier tool, said first moulding component comprising said first moulding compound,
- placing the carrier tool and the attached first moulding component in a mould comprising first and second mould parts that are configurable in opened and closed configurations, wherein a mould cavity is defined between the first and second mould parts in the closed configuration,
- closing the mould and applying a first moulding process, so that the first moulding component adheres to the first mould part,
- opening the mould and removing the carrier tool while leaving the first moulding component adhered to the first mould part,
- either (i) placing a second moulding component in the mould, said second moulding component comprising said second moulding compound, then closing the mould, or (ii) closing the mould, then injecting a second moulding component into the mould, said second moulding component comprising said second moulding compound,
- applying a second moulding process to shape the first and second moulding components to the mould cavity, and bond the first moulding component to the second moulding component to form a moulded article, and
- opening the mould and removing the moulded article.
