A method and apparatus for constructing a tubular assembly 40 comprising an inner portion (24) and a further portion (23) surrounding the inner portion. The inner portion (24) comprises reinforcement (37) and the further portion (23) being formed from a strip (50) of material comprising two opposed longitudinal marginal side portions (53). The apparatus comprises an assembly station (220) comprising a wall (253). The apparatus comprises means for advancing the inner portion (21) along a first path (231) extending passed the wall (253), and means for advancing the strip (50) along a second path (232) and causing the strip to encircle the wall (253) and thereby wrap about and surround the inner portion (21). The apparatus further comprises means (321) for introducing resinous binder into the reinforcement (37) as the strip (50) is being wrapped about the inner portion (21).

A bladder mandrel package, used to manufacture a composite structure, includes a mandrel and a wrap ply, surrounding the mandrel to form a wrapped mandrel. The bladder mandrel package also includes a first radius filler, coupled to the wrap ply at a first radius of the wrapped mandrel, and a second radius filler coupled to the wrap ply at a second radius of the wrapped mandrel. The mandrel, the wrap ply, the first radius filler, and the second radius filler are consolidated to from the bladder mandrel package.

Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing; Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.

A method produces an elastically deformable molded part having a number of undercut molded-part regions, by use of a mold. To provide a technique which makes it possible to produce individual molded parts which are elastically deformable and have undercut regions from soft materials in a precise and cost-effective manner, a method is performed in which a molded-part material is introduced into the mold. The mold has a shaping contour with a number of special contour regions, which are configured for shaping the number of undercut molded-part regions of the molded part, and in which the molded part is removed from the mold by at least partially deforming the mold together with the molded part therein in such a way that the molded part elastically deforms and the mold at least partially, but in any event to the extent of the special contour regions, breaks up.

Within examples, elastomeric apparatuses for use in manufacture of a composite component, and methods for altering a surface rigidity of an elastomeric apparatus for use in manufacture of a composite component are described. In one example, an elastomeric apparatus comprises an elastomer housing, and a plurality of magnets within the elastomer housing at predetermined positions to provide surface rigidity to the elastomer housing based on one or more alignments of certain magnets of the plurality of magnets due to magnetic forces. An increase in temperature causes a loss in one or more of the magnetic forces of one or more of the plurality of magnets resulting in a reduction of stiffness of the elastomer housing at corresponding predetermined positions.

An example mandrel for processing a part is described including a plurality of elastomeric components aligned end to end and spaced apart linearly to form a segmented mandrel body, and compressible interconnections positioned within spacing between adjacent elastomeric components and abutting the adjacent elastomeric components. The compressible interconnections allow the plurality of elastomeric components to expand axially due to thermal expansion resulting in a distribution of pressure. An example method for fabricating a composite part is also described including placing a base composite layer into a cavity of a tooling surface, inserting a mandrel into the cavity of the tooling surface such that the base composite layer is between the mandrel and the tooling surface, applying a skin to the mandrel and the base composite layer forming a package, enclosing the package in a vacuum bag and curing, and removing the mandrel from the cavity of the tooling surface.
