Hybrid component with high strength/mass ratio and method of manufacturing said component

A hybrid component comprising:

• a first part, termed the soft part, composed of fibres embedded in an organic resin matrix;
• at least one second part, termed the hard part, made of a material selected from the group consisting of metals, metallic alloys and ceramics, said hard part having at least one place where its dimension in any direction is at least 8 mm;
• and
• a transition layer between said soft part and said hard part and completely separating said soft part from said hard part, said transition layer being made of a composite material including a matrix which is weldable to the material of said hard part and reinforcement fibres embedded in said matrix, said transition layer being maintained against said soft part by the reinforcement fibres, and said reinforcement fibres being formed by extensions of said fibres of said soft part into at least a periphery of a boundary between said soft part and said transition layer.
