A composite blade includes a composite blade body including reinforced fibers and resin; a metal layer provided on an outer side of a leading edge section including a leading edge that is a part of the composite blade body on an upstream side of an air stream, the metal layer having a thickness of equal to or larger than 5 micrometers and equal to or smaller than 100 micrometers; an adhesive layer provided between the composite blade body and the metal layer to bond the metal layer to the composite blade body; and an electric insulating layer provided in contact with a surface of the leading edge section of the composite blade body, the surface being on the side on which the metal layer is provided, the electric insulating layer having an electric insulating property.

Disclosed is joining device for joining a trailing end of a first strip to a leading end of a second strip to form a tire component. The joining device includes a support member with a support surface and a retaining member with a retaining surface for retaining the second strip. The joining device is arranged for positioning the leading end of the second strip in a joining orientation in which said leading end is closer to the support plane than the rest. The joining device also includes a control unit for controlling a relative movement between the support member and the retaining member with a first component in a placement direction to place the leading end of the second strip and a second component in a joining direction to bring the leading end of the second strip into contact with the trailing end of the first strip.

An apparatus and method for producing a composite part, such as a reinforced composite part, are provided that enable control over the fiber or other particle orientation within each layer of the part during manufacture. The apparatus and method employ a print head including a dispensing tip and a magnetic assembly controllable to apply a magnetic field at a print location adjacent the dispensing tip outlet.

A method for forming a silicone container having a reinforced rim. A layer of adhesive is applied to the outer surface of a metal ring. The adhesive layer is covered with a first plug of unvulcanized silicone. The first plug of unvulcanized silicone is then vulcanized to form a vulcanized silicone covered metal ring. The vulcanized silicone covered metal ring is then inserted into a mold along with a second plug of unvulcanized silicone. The second plug of unvulcanized silicone is then vulcanized so that it binds with the vulcanized silicone covered metal ring to form a silicone container having a reinforced rim. In one preferred embodiment the silicone container having a reinforced rim is a bowl. In another preferred embodiment the silicone container having a reinforced rim is a cup.

An aerostructure is provided. The aerostructure may comprise an airfoil extending from a leading edge to a trailing edge, the airfoil comprising a stiffness and a camber, and a shape memory alloy (SMA) mechanically coupled to the airfoil via a resin, the SMA configured to be coupled to a current source, wherein at least one of the stiffness or the camber changes in response to a phase change of the SMA.

A sandwich component including at least two cover layers and one core layer containing wires including shape-memory metal. A process for producing the sandwich component is also disclosed.

A pipe-forming apparatus with which a spiral pipe can be formed using a simple configuration without an inner periphery restriction body. A driving part (10) of a pipe-forming apparatus (3) presses a following strip portion (92) toward a pipe end portion (91e) of a preceding spiral pipe portion (91) obliquely with respect to a machine-height direction HD. A pipe end guide is constrained in a machine-width direction WD with respect to the pipe end portion, and slidably engaged in a propelling longitudinal direction LD. A pressing force for the following strip portion provides a fitting force between the following strip portion and the pipe end portion, and a propelling force for forward propulsion. A pipe is formed in a state where a part other than a partial part at which the pipe-forming apparatus is provided in a circumferential direction of the pipe end portion is released from the pipe-forming apparatus.

The present invention relates to a process for producing a fiber-foam composite (FSV1), wherein a first fiber material (FM1) is applied to a first foam body (SK1) to give a first structured fiber surface (FO1) to which a second foam body (SK2) is subsequently applied to give the fiber-foam composite (FSV1).
