摘要:
In accordance with the present invention, there is provided a method for the forming or curing of polymer composites, the method including the step of: forming or curing the polymer composite in the presence of a heated vapour.
摘要:
There is provided an apparatus (2) for the forming or curing of a fibre-reinforced polymer composite material (10). The apparatus (2) comprises a first layer of material (4) positioned to overly the fibre-reinforced polymer (10); a second layer of material (6) positioned to overly the first layer (4) to define a chamber (8) therebetween. The apparatus (2) further comprises a vapour source (16) and a fluid communication path having; a transfer section (18) in fluid communication with the vapour source (16) and chamber (8), and, a return section (20) in fluid communication with the chamber (8) and the vapour source (16).
摘要:
A method of rehabilitating or remediating a structure comprises forming a sealed region (18) over or about a portion of the structure and drawing air from the region (18). A supply of a structural adhesive is placed in fluid communication with region (18) so that as air is drawn from the region (18) the adhesive flows into the region and fills discontinuities in the structure. Fiber reinforcement or other strengthening material is placed in the region (18) so that the adhesive also penetrates through the material to band the material to the structure.
