HiTape® innovative high performance dry unidirectional reinforcements are designed to meet the requirements of Aircraft Primary Structures made by cost-effective Out of Autoclave (OOA) technologies such as vacuum infusion or injection.
Customer evaluations have demonstrated that significant cost-savings are achievable with HiTape® and the associated vacuum infusion process. The materials allow the part design to be optimized, including function integration. The automated dry preform process is simplified, without any splicing of materials or polythene film to remove. There is no need to apply pressure to consolidate the preform and remove air as this occurs later when vacuum is applied. Very high preform lay-up outputs are achieved and another cost-saving benefit is that no refrigerator storage is required due to the dry nature of the reinforcements.
HiTape® Reinforcements for Primary Aircraft Structures
An innovative composite solution for cost effective Primary Aircraft Structures:
Hexcel is developing, internal or in collaboration with external partners, all steps, from dry preform to infusion, of the manufacturing process of composites parts made by OOA RTM/infusion technologies. This includes academic work with Mines St Etienne Engineering School, to understand, predict and model the resin flow through HiTape® dry preform. All this work aims to ease and to support the introduction of these materials and technologies in the aerospace markets.
