Compression moulding of hinges for aerospace with recyclable materials

摘要

Despite a broaden for carbone fibre reinforced polymers (CFRP) in aeronautics, numerous metallic parts are still in use. Besides coefficient of thermal expansions between materials, this leads to problems related to galvanic corrosion for aluminium and for securing titanium supplies. The use of these two metals also implies a non-negligible cost. In addition to these constraints, there is the issue of recycling. This article describes an alternative for overcoming these issues on hinges for helicopter doors using a compression-moulded carbon-fibre reinforced thermoplastic material.
