Problems solved by technology

Typical RTV silicones are highly viscous and are thixotropic which makes them difficult to spray as the material does not flow easily
Therefore, it is difficult to obtain a bag with a uniform thickness over a large area, since the article must be wiped after being applied to the surface
Additional solvents can be use...

Embodiment Construction

[0030] Reference will now be made in detail to possible embodiments of the present subject matter, one or more examples of which are illustrated in the drawings. Each example is provided to illustrate the subject matter, not as a limitation. In fact, features illustrated or described as part of one embodiment can be used in another embodiment and still form a further embodiment. It is intended that the subject matter cover such improvements and variations.

[0031] According to one embodiment, the present subject matter provides a method of making a film for use as a vacuum bag. as in figure 1 As described in , the method includes providing a substantially non-porous working surface 10, which in this illustration coincides with the mold surface 3 of the mold 1, such a surface being generally smooth and substantially non-porous. The working surface 10 defines the size and shape of the vacuum bag film 20 formed thereon, and when the liquid natural rubber 7 is sprayed on the w...

Abstract

The invention discloses a method for making a membrane for use as a vacuum bag, a natural rubber vacuum bag made using such methods, and methods for using such a natural rubber bag to form a composite article. One method can include providing a substantially non-porous working surface having a desired shape for forming a vacuum bag, spraying at least one layer of a natural rubber liquid over at least a portion of working surface, and solidifying the natural rubber liquid to form a membrane having a shape substantially corresponding to that of the working surface. The membrane formed being elastically deformable and substantially impermeable for functioning as a vacuum bag in Vacuum Assisted Resin Transfer Molding, debulking, compaction, or similar processes.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Patent Application Serial No. 60 / 903,056, filed February 23, 2007, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The subject matter described herein relates generally to the field of vacuum bag construction. More particularly, the subject matter described herein relates to methods for making natural rubber vacuum bags for use in vacuum-assisted resin transfer molding, calendering, compacting, or similar processes, natural rubber vacuum bags made by spraying, and A method using a natural rubber vacuum bag manufactured by the spraying method. Background technique [0004] A composite is broadly defined as combining two or more different materials to produce a new material with synergistic properties not found in the individual components. In fact, the word "composite" is often associated with reinforced plastic materials such as fiberglass ...
