Double Bag VARTM for High Temperature Composites, Phase II

The process known as double bag vacuum assisted resin transfer molding (DBVARTM) was developed by NASA to help deplete by products. To date, the NASA DBVARTM process has reduced void content to approximately four to five percent. This number has fallen short of the goal of two percent. During the Phase I effort, San Diego Composites (SDC) was able to reduce the void content to 0.8 percent to 1.5 percent. There are three primary technical objectives to the Phase II effort. The first objective is to perform a trade study to evaluate and optimize the effect of stitched performs. Stitching has had a large effect on the void content in the laminate and several different stitching variables will be evaluated. The second objective is to transition the work done in Phase I to larger components. These components will consist of larger plates and structures will be evaluated using non destructive testing along with mechanical testing. At the end of the Phase II effort, a full scale component will be fabricated, evaluated using non destructive testing, and then the component will be tested. The final objective is to transition the technology to Boeing Phantom Works. This objective will demonstrate that the process developed in a laboratory can be reproduced at any facility. By the end of the Phase II program, the Technology Readiness Level (TRL) is expected to be 5-6.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
