Disclosed are a multilayer prepreg structure and a method of manufacturing the same. The multilayer prepreg structure includes a prepreg layer formed by impregnating a carbon fiber fabric with a first resin, and a fixed layer formed of a second resin having a higher curing rate than the first resin and provided on one surface of the prepreg layer.

A connecting port arrangement for use in an apparatus for producing a composite material component comprising a base member attached to a surface of a foil adapted to seal a mold of the apparatus for producing a composite material component. The base member is provided with a channel extending therethrough. The connecting port arrangement further comprises a punch member adapted to be inserted into the channel formed in the base member and provided with a cutting device suitable to cut at least one opening into the foil.

A flanged bearing ring comprising a flange part joined to a ring part. The flange part is at least partly made of a fiber-reinforced matrix material, which is overmolded to the ring part. The flange part further comprises a first connection interface for enabling a component such as a vehicle wheel to be screwed or bolted to the flange part. The first connection interface comprises a plurality of bolt inserts which are embedded in the fiber-reinforced matrix material. At least one bolt insert is joined to the ring part by a continuous fiber tow that is wound around part of an outer surface of the bolt insert and of the ring part. Suitably, each bolt insert is joined to the ring part in this manner.

A method for combining heterogeneous metal parts includes steps of: a) disposing a first metal part and a second metal part in a lower mold cavity of a lower mold, the lower mold cavity having a lower portion and an upper portion, the lower mold including a channel that communicates with an external environment; b) combining an upper mold and the lower mold with an upper mold cavity of the upper mold facing the lower mold cavity, the upper mold cavity being defined by an inner base surface and an inner surrounding surface; and c) injecting a bonding adhesive into the channel so as to fill the lower portion of the lower mold cavity and a gap between the first metal part and the second metal part with the bonding adhesive.

A steering knuckle comprising a bearing connection point for connecting a bearing to the knuckle and comprising a further connection point for connecting the knuckle to a further component. The bearing connection point is formed by a first insert and the further connection point is formed by a second insert, which are joined by a composite body comprising a fiber-reinforced material that is overmolded to the first and second inserts. The bearing connection point and the further connection point are additionally joined by one or more continuous fiber tows that are wound around part of a radially outer surface of the first insert and of the second insert.

An aerodynamic profile for an aircraft, comprises a core (6, 7, 8) made of foam, a skin (11, 12) defining an outer surface of the wing and cloths (14) form-ing spars and/or ribs. The profile comprises a wing, a canard, a horizontal stabiliser, a vertical stabiliser, an aileron, a flaperon, a wingtip winglet, an elevator, an elevon, a rudder or a flap.
