  • Semi-rigid tool having sections that vary from one another in rigidity
    Patent number: 8353696
    Abstract: The present invention relates to a manufacturing tool (13, 14) and method for use in forming polymer matrix composite products such as carbon fiber composite products. The tool comprising a first and a second portion defining a cavity (15) therebetween in which the product is built before curing. The rigidity of the second portion (13) of the tool is selected based on the required deflection of the second portion of the tool under the curing conditions, in order to maintain pressure on the laminate during the entire cure. The second upper portion (13) is shown haring varying thicknesses (16A, 16B and 16C) which results in different rigidity of these regions.
