Abstract

Panels made of high tensile filaments impregnated with resin are stiffened by a series of ribs of composite structure having a core of resin-impregnated aligned fibres between zones of similar structure to the surface skin and laminated thereto. The covers of stiffeners are prefabricated in the form of 'U' profiles moulded over a core of material having a relatively high coefft. of thermal expansion, e.g. silicone rubber sleeves over a solid bar. Dilation of the core at moulding temps. compresses the impregnated filaments to express excess resin. Sets of parallel covers are laminated to the main panel, while the gap between adjacent webs is filled with aligned impregnated fibres and the composite lay-up is consolidated by pressure from an impermeable flexible cover over an evacuated mould. Suitable for mfr. of curved semi structural panels for aerofoils etc. to minimise the need for an ancillary skeleton. Esp. claimed are structures reinforced with fibres of c or B impregnated with e.g. epoxy resin.
