The paper describes the application of composite materials to the design of crash resistant beam and frame elements for helicopter subfloor structures, and discusses alternative fabrication technologies for these structural elements. These elements require a dual function structural concept with load carrying capability under flight loads and energy absorption under crash loads. The realisation of this dual function by innovative design with fibre reinforced composite materials is described. In order to utilise these lightweight structural concepts in helicopters, cost effective technologies for series production of composite components are required. The paper discusses three fabrication methods based on autoclave technology, resin transfer moulding (RTM) and thermoforming, taking a sine-wave floor beam as a demonstrator component for the technologies.
