A method of manufacturing a lightweight building element assembly is disclosed. The assembly firstly comprises a first object (1) being a lightweight building element that has a first outer building layer (11) and an interlining layer (13). The assembly further comprises a second object (2) secured to the first object. The method comprises firstly providing the first object, wherein the first object has an indentation (19) formed by the first outer building layer. The indentation may form a blind opening or a through opening in the first object. The method further comprises providing the second object (2), wherein the second object comprises an outer surface portion of a thermoplastic material, wherein the outer surface portion is a lateral outer surface portion with respect to an axis. The second object is brought in contact with the first object so that the lateral outer surface is in physical contact with the sidewall (14), and mechanical energy is coupled into the second object so as to cause energy absorption due to friction between the lateral outer surface and the lateral wall, until a flow portion of the thermoplastic material becomes liquefiable and flows relative to the lateral wall. After re-solidification of the thermoplastic material, the flow portion secures the second object to the first object.

A system including a polymeric sheet. The polymeric sheet comprises a base sheet having a first surface and a second surface opposite the first surface and a multiplicity of spaced rails projecting from the first surface of the base sheet. The rails comprise a stem portion attached to and substantially upright from the first surface of the base sheet and a top portion on the distal end of the stem opposite the base sheet. The top portion comprises a first surface opposite the base sheet and a second surface facing the first surface of the base sheet. Additionally, the rails have a length greater than the width of the stems. The first surface of the base sheet, the second surface of the top portion and the surface of the stem defines a cavity with walls, and an adhesive coated on at least a portion of the cavity wall.

Provided is a method for manufacturing a porous midsole the method including: a cotton-beating step (S1) of forming a midsole base (10) having porous voids 16 by mixing low melting fibers (12) and high melting fibers (14); and a thermoforming step (S2) of bonding and fixing the high melting fibers into a compressed state by the melt adhesive strength of the low melting fibers (12) by compressively thermoforming the midsole base (10) at a melting point temperature of the low melting fibers (12).

A method for bonding thermoplastic fiber-composite parts comprises providing surface texture on one or both parts being bonded, and/or providing both parts with engagement features. Such surface textures and engagement features have a specific geometry and fiber alignment that facilitate fibrous interlock between the two parts at a bonding interface via in-situ consolidation.
