摘要:
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 v 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.
摘要:
The present invention relates to a vacuum insulation panel (1) comprising a core material (2) with open porous structure and a barrier (3) that holds the core material (2) together. The open porous core material (2) is filled into a barrier (3) preferably together with a getter material, depending on the material properties forming the core material (2) and vacuumed. Thus, a vacuum insulation panel (1) is realized comprising the open porous core material (2) having low thermal conductivity coefficient, with increased insulation effectiveness.
