Reinforced laminated sailcloth - has angled strands between layers to be passed continuously through a roller gap

The process to develop a continuous reinforced and laminated cloth, as a sailcloth, uses two rolls of fabric where the surface of at least one is clad with an adhesive. The two materials are passed to a gap between two rollers together with reinforcement strands between the fabric layers. Before the reinforcement strands enter the roller gap zone, they are led through one or more openings in a continuous belt which moves constantly and at a given speed across the line of the two fabric layers. The two fabric layers, and the strands between them, pass continuously through the roller gap so that a laminated fabric is continuously produced and secured. The reinforcement strands are of a polymer with a high yield strength, pref. of aramide, drawn from individual bobbins mounted in a frame on a second continuous belt which travels synchronously with the first belt carrying the guide openings. The strands pass through adjustable draw tensioners before entering the guide openings. The guide belt ...

Composite with several layers of fiber reinforcement has additional yarn running transversely through layers and also partially parallel to them

A composite with several layers (13a) of fiber reinforcement, e.g. fabric, in an adhesive resin has a transverse yarn (16a) running through the layers. The yarn runs in straight sections (17a, 18a), partially at an angle (17a), e.g. 15 to 25 degrees and partially parallel (18a) along the outer surface (14a, 15a), generally in a zigzag manner. The free end (20a) of the yarn protrudes sideways at the end (12a). An Independent claim is also included for the process of assembling the reinforcing layers, taking the reinforcing yarn (16a) through them, tensioning the yarn at the free end (20a) and compressing the layers. The assembly is then saturated with resin and bonded. Tensioning can take place after the layers have been compressed and several reinforcing yarns can be used.

Methods and Apparatus for Digital Composites

In exemplary implementations of this invention, a digital material comprising many discrete units is used to fabricate a sparse structure. The units are reversibly joined by elastic connections. Each unit comprises fiber-reinforced composite material. Each unit is small compared to the sparse structure as a whole. Likewise, in a sparse structure made from this digital material, the number of types of units is small compared to the total number of units. The digital material is anisotropic.

Furthermore, different units in a single sparse structure may be oriented in different directions and in different, non-parallel planes. In some cases, the digital material is reinforced with carbon fibers, and connections between units are stronger than the units themselves. The small discrete units may be assembled into a strong, lightweight sparse structure, such as an airframe.

Thermoplastic Prepreg Containing Continuous and Long Fibers

A prepreg that contains a plurality of unidirectionally aligned continuous fibers embedded within a thermoplastic polymer matrix is provided. In addition to continuous fibers, the prepreg also contains a plurality of long fibers that are combined with the continuous fibers so that they are randomly distributed within the thermoplastic matrix.
