Abstract
Abstract A method for molding a composite article by injecting a plastics material resin into the fibers within a mold by a continuous web of fibers that is laid in a mold in such fashion that a honeycomb structure is produced without the web crossing itself.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
46 words
A method of moulding a composite article by injecting a plastics material resin into fibres within a mould characterised in that a continuous web of fibres is laid in a mould in such a fashion that a honeycomb structure is produced without the web crossing itself.
Claim 2
Independent Claim
46 words
A method of moulding a composite article by injecting a plastics material resin into fibres within a mould characterised in that a continuous web of fibres is laid in a mould in such a fashion that a honeycomb structure is produced without the web crossing itself.
Claim 3
Dependent Claim
35 words
A method as claimed in claim 1 in which the honeycomb is laminated to a plate during moulding by providing a flat sheet of fibres contiguous with the honeycomb structure and injecting the whole simultaneously.
Claim 4
Dependent Claim
20 words
A method as claimed in claim 2 in which a honeycomb structure is provided on either side of the plate.
Claim 5
Independent Claim
26 words
A method as claimed in any of claims 1 to 3 in which the fibrous web forming the honeycomb is continuous throughout the article being moulded.
Claim 6
Independent Claim
23 words
A method as claimed in any of claims 1 to 3 in which the web contains substantially parallel fibres in its longitudinal direction.
Claim 7
Independent Claim
50 words
A method as claimed in any of claims 1 to 3 in which the web is a laminate of mainly longitudinal fibres with some fibres arranged at a angle to the longitudinal direction in order to cater for the direction of stress likely to be found in the finished composite.
Claim 8
Dependent Claim
39 words
A method as claimed in claim 6 in which the web comprises 70% of longitudinal fibres together with 15% of fibres arranged at +45° to the longitudinal direction and 15% of fibres arranged at -45° to the longitudinal direction.
Claim 9
Dependent Claim
12 words
A composite article produced by a method as claimed in claim 1.
Claim 10
Dependent Claim
12 words
An article as claimed in claim 8 used as a simple grating.
Claim 11
Dependent Claim
21 words
An article as claimed in claim 8 having an integral sheet and used as a structural component, e.g. a floor panel.
