A method for manufacturing a thin film structural system including a thin film structure includes depositing a reinforcing material in a liquid form in a predefined pattern on a thin film membrane, and transforming the reinforcing material in the predefined pattern to form a reinforcing element connected to the thin film membrane. The reinforcing material may be deposited in a melted form and solidified by cooling, may be transformed by a light or laser induced chemical reaction, or may be deposited and solidified such that the reinforcing element is at least partially embedded in the thin film membrane. The predefined pattern may redistribute loads around a damaged portion of the thin film structure, or define a hinge, a folding line, a stiffening feature. The reinforcing element may be electrically, optically or thermally conductive, to communicate with a device included in the system. The system may be a space structure.

A method for manufacturing a lining element is provided. The method comprises laying a textile membrane onto a positive molding tool, applying first fibers and a matrix material onto at least one first region of the textile membrane for creating a semi-finished product of a framework supported textile, providing at least one sealing element along outer edges of the molding tool, covering the textile membrane and the at least one sealing element in an air tight manner by a covering means, evacuating the space between the molding tool 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.

The invention provides a prepreg comprising matrix and fibres, having deposited thereon a plurality of regions raised at least 5 micrometres relative to the surface of the matrix, a method of preparing such a prepreg, a method of curing a laminate of a plurality of such preprags and the cured laminate produced by such a method.
摘要:
This invention relates to methods and apparatus for producing a discretely striped, multi-property foam and the products and articles produced thereby. The invention provides a pre-foam stream at a first pressure and intermittently injects at least one additive into the pre-foam stream at a pressure higher than the first pressure, providing a laminar flow pre-foam stream with alternating segments having different properties. The pre-foam stream is poured onto a surface and cures into a discretely striped foam product which may be used for many purposes such as but not limited to padding, clothing, toys, or bedding.
摘要:
A prefabricated underlay material (1) for location between upper surface of a load-bearing floor (8) and a continuous surface material (9), which underlay material comprises a substantially flexible sheet material (2) and dampening projections (3) formed of porous resilient material on one surface of the sheet material and distributed along the surface. Dampening projections (3) comprise strips (13) of foamed polymer or polymer mixture bonded to a first surface (11) of the sheet material without deformation of the surface thereof, which strips are located continuous, or intermittently continuous, with intervals (S) and are either principally straight or substantially undulating.
