摘要:
The invention relates to a method for preparing a fiber-reinforced article, having attached to at least part of its surface a layer of a material that is not fiber-reinforced, comprising the steps of 1) preparing a shell via an additive manufacturing technique, the shell —being of a material that is not fiber-reinforced; and —having a surface that corresponds in negative relief to a surface of the article formed in step 3); thereafter 10 2) applying —long and/or continuous reinforcement fibers; and —a curable resin to the surface of the shell that is in negative relief, to form a mixture of curable resin and long and/or continuous reinforcement fibers on the 1 surface of the shell, so that the surface of the mixture contacting the shell adopts the shape of the surface of the shell that is in negative relief; thereafter 3) curing the curable resin to form the fiber-reinforced article having attached to at least part of its surface a layer of a material that is not 20 fiber-reinforced.

A hybrid mold includes (a) an Invar® eggcrate structure, (b) an Invar® interim working surface and (c) a CF composite material overlay. The eggcrate and interim working surface are welded or otherwise connected together to form a unitary base mold. The CF overlay is bonded to the interim working surface. The CF overlay is easily reconfigurable and can be replaced without destroying the integrity of the base mold.

The object of the present invention is a layered semi-finished product having a layer sequence containing at least one layer of an unconsolidated fabric of reinforcing fibres. At reduced pressure, this layer sequence is arranged between a top and a bottom film connected to each other along their periphery in a pressure-retaining manner. In advantageous modifications of the layered semi-finished product according to the invention, the preforming of the semi-finished, as well as the inclusion of metallic inserts or other components into said semi-finished is intended. Furthermore, a method for producing the layered semi-finished product according to the invention is described.

摘要:
A system for producing composite or bonded metal components including: first and second pressure chambers, each pressure chamber having an elastically deformable chamber wall; means for circulating fluid at an elevated temperature and pressure through each said pressure chamber; and at least one mould assembly including at least one separate mould section providing a mould cavity within which a composite or bonded metal lay-up can be located; wherein when the system is in use, the pressure chambers are held together with the elastically deformable chamber walls located in opposing relation, the at least one mould assembly containing a said lay- up being accommodated between the chamber walls while fluid at elevated temperature and pressure is circulated through each pressure chamber such that the lay-up can be compressed and cured or formed.
摘要:
A columnar structure comprises a generally hollow laminate core, an outer composite skin, and a sleeve-like reinforcement. The sleeve-like reinforcement surrounds the laminate core and is sandwiched between the laminate core and the outer composite skin for reacting compressive loads imposed on the columnar structure.

The invention is directed to a process for the making of a product out of laminated composite material. The process in general comprises preforming at least one layer of material such that it corresponds to a surface of a part; applying layers of fibers to the preformed layer of material; and bonding the fibers by a resin to form a laminated composite material.
摘要:
A method comprising building at least one three-dimensional model and a support structure using a layer-based additive technique, where the at least one three-dimensional model is at least partially encased in the support structure, and where the support structure functions as a shipping package for the at least one three-dimensional model.
