摘要:
In order to manufacture a protected profile structural part (14) of a fuselage (10) of an aircraft, a sealant mold having a mold cavity (22) having a cross-section that matches a portion of the profile structural part (14) on which the surface (18) to be protected is disposed is prepared. The mold cavity (22) is filled with uncured wet sealant (28) which is subsequently cured into a cured sealant member (30). The cured sealant member (30) is then attached to the finished structural profile part (14) in a non-movable manner so as to form a protective liner on the surface (18) to be protected and generate the protected profile structural part (14).

System for forming a micro-truss reinforced structural member (10, 12) which includes a first collimated light source (14) and a reservoir (20) containing a volume of photo-monomer resin (18) wherein the first collimated light source (14) is positioned spaced apart from the photo-monomer resin (18). The system further includes a first face sheet structure (24) defining at least one bore (26) which extends through the first face sheet structure (24) wherein a portion of the first face sheet structure is positioned under a surface of the volume of photo-monomer resin such that photo-monomer resin (18) is positioned within the bore (26).

A method for manufacturing a lining element comprises laying a textile membrane (6) onto a positive molding tool (2), applying first fibres (8, 10, 12, 14) and a matrix material onto at least one first region (9, 11, 13, 15) of the textile membrane (6) for creating a semi-finished product of a framework supported textile, providing at least one sealing element along outer edges of the molding tool (2), covering the textile membrane (6) and the at least one sealing element (22, 24, 26, 28) in an air tight manner by a covering means, evacuating the space between the molding tool (2) and the covering means and curing the matrix material by heating the semi-finished product. Thereby, a lining element with a low weight and at the same time a sufficient directional stability is provided that furthermore allows to easily recycle the components of the lining element.

摘要:
In a method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, a polymeric resin material is applied onto the surface of a base substrate (12) in a precise predetermined pattern which is to be imparted onto products manufactured with the belt. The polymeric resin material is deposited (14) in droplets having an average diameter of 10µ (10 microns) or more. The polymeric resin material is then set by means (36) appropriate to its composition, and, optionally, may be abraded (44) to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.
摘要:
L'invention concerne une tôle métallique revêtue d'une ou de plusieurs couches (2) de résines éventuellement différentes, caractérisée par des renflements (5) en bourrelet annulaires ou discoïdes dans au moins une des couches de résines. L'invention concerne également des procédés pour revêtir des tôles métalliques, les films stratifiés thermoplastiques utilisés à cet effet et l'emploi de ces tôles métalliques revêtues pour fabriquer des récipient d'emballage.
摘要:
The invention relates to a method for reinforcing an existing base structure with at least one reinforcing structure (1) so as to form a support structure, having the following steps: producing the at least one reinforcing structure (1), connecting the at least one reinforcing structure (1) to the base structure such that the at least one reinforcing structure (1) is connected to the base structure in a connection position, and the base structure together with the at least one reinforcing structure (1) forms the support structure. The base structure is to be inexpensive and reliably reinforceable with little technical complexity using reinforcing structures (1). This is achieved in that the at least one reinforcing structure (1), in particular all of the reinforcing structures (1), is or are made of a composite material comprising fibers and a matrix by means of pultrusion and/or extrusion, and a pultrusion unit (6) and/or an extrusion unit (7) is moved in space such that the at least one reinforcing structure (1), in particular all of the reinforcing structures (1), is or are pultruded and/or extruded onto the base structure at the respective required connection position after the pultrusion and/or extrusion.
