Abstract
Current NASA programs, such as Adaptable, Deployable Entry and Placement Technology (ADEPT) and Woven Thermal Protection Systems (WTPS) are looking to fill a gap in ablative TPS for future missions to Venus and Saturn, human missions beyond Lunar, and Mars Sample Return Missions. Both of these programs rely on the use of 3D woven carbon fiber preforms. Therefore, there is a need to be able to predict the properties and performance of a woven material. Validation of predictive modeling tools would allow for the use of these tools to design and optimize the 3D weaves, significantly reducing the cost of fabrication and testing of a variety of configurations. While there are proven tools for the prediction of laminate composite properties, textile composites are relatively new materials and much less effort has been focused on modeling this class of materials. Materials Research & Design (MR & D) has experience in working with and designing 3D woven preforms for use in composite material reinforcement and has developed a suite of analytical tools to define the detailed geometry of 3D woven preforms for use in calculating material properties. However, these tools currently do not have the capability to predict material strengths. Within the proposed Phase I effort, MR & D will enhance the existing tool by incorporating the ability to calculate material strengths of 3D weaves. Strength predictions will be made for two different 3D woven hybrid preform reinforced phenolic panels and compared to measured test data for validation.
