Problems solved by technology

These attempts often result in failure to achieve full vacuum leading to possible product defects, poor resin cure and poor resin-to-matrix migration, leading to potential product failure
For this reason, attempts have been made to use multiple vacuum barriers to ensure vacuum integrity, but this solution adds complexity and expense to the process

Embodiment Construction

[0026] Some exemplary embodiments of the invention are described below and illustrated in the accompanying drawings. These described embodiments are only for the purpose of demonstrating the embodiments of the present invention, and should not be construed as limiting the scope of the present invention. Other embodiments of the invention, certain modifications and improvements of the described embodiments will occur to those skilled in the art, and all such altered embodiments, modifications and improvements are within the scope of the invention.

[0027] The tools and methods generally include two or more tools that can be connected to each other to form the desired mold profile. The composite material is then applied on top or placed on the tool. The composite material can then be packed into vacuum barriers or bags which can be sealed around the composite material and secured to the surface of one of the tools. After curing, parts can be selectively removed to allow compl...

Abstract

A multi-segment tool and tooling system for vacuum forming a composite part. A tool can include a first tool having first and second surfaces. A second tool can have an opening positioned on a first tool in a location other than the first surface or the second surface. The first tool and second tool can receive at least a portion of a preform composite. The first tool can have a vacuum barrier attached to the first surface and to the second surface encapsulating the preform composite and the second tool. A tooling system can include a first tool having a core and a base with a core extending upwards from the base. A second tool can be positioned upon the core where the core extends above the second tool. A vacuum barrier sealed to the base and the core can include a composite, the first tool and the second tool.

Description

technical field [0001] The present invention relates generally to a multi-segment tool and method for vacuum forming composite parts, and more particularly to a tool and method for composite forming aircraft nacelles and related parts. Background technique [0002] Aircraft structures have many parts that have complex shapes with many curved sections. For example, aircraft pods and pylon (pylon) systems, thrust reversers and rocket propulsion chambers and other components have a variety of complex shapes. Several methods are known for forming complex shapes. For thermoplastic and thermoset polymers, multiple tools can be used in injection and compression molding operations to form complex shapes. Metal forming processes have used cast plugs to facilitate the shaping of metal rocket booster chambers having an hourglass shape. However, these methods are not readily applicable to forming complex parts using vacuum bag lamination processes. [0003] Vacuum bagging is a metho...
