A method of manufacturing a composite element. A stack of plies is assembled on a lay-up table, each ply comprising a plurality of reinforcement elements such as dry-fibres. A first part of the stack of plies is bound to form a partially bound stack of plies, a second part of the stack of plies remaining unbound. The partially bound stack of plies is press-formed in a mould cavity between a pair of mould tools to form a shaped pre-form, plies in the second part of the stack sliding against each other during the press-forming. A liquid matrix material is injected into the shaped pre-form in the mould cavity and subsequently cured.

A foamed delivery system having at least two components: a foam and an additive that is associated with, carried by or delivered by the foam. The foam is a stable foam that has a liquid matrix, gas bubbles and a structuring agent that forms a lamellar or vesicular cage structure without generating a gel imparting a rubbery texture. The lamellar cage structure entraps at least a substantial portion of the gas bubbles and liquid matrix therein to retain the gas bubbles and liquid in a sufficiently compact structure that substantially prevents drainage of the liquid matrix and coalescence and creaming of the gas bubbles to maintain stability of the foam even when the foam is subjected to heat shock. Combined with the stable foam structure the distribution and release of the additive during application is significantly improved.
