Abstract
A reinforcement sheet has a composite layer including fibres and a polymer A and a coating layer including polymer B, each polymer having at least 65 mol % of a repeat unit of formula: wherein for each polymer A and B, t1, and w1 independently represent 0 or 1 and v1 represents 0, 1 or 2. A method of forming the reinforcement sheet is also disclosed, in addition to a method for forming an article comprising a laminate of the reinforcement sheets and the article comprising such a laminate. The repeat unit may be ether-ether-ketone.
