Принадлежит:

Chlorinated rubber moulding is reinforced with 2-80 (10-60) wt.% fibres contg. min. 50 (min. 70) wt.% cured novolak fibres. The mouldings have excellent flame retardancy and improved mechanical properties, whilst the elasticity of the rubber is not impaired. The composite can be in the form of paper, sheet, web, tube, packing material or plate. The fibre can be in the form of yarn, cloth, woven, knitted or nonwoven fabrics or paper. The novolak fibres are produced by melt spinning, treating with an aldehyde and curing. The rubber blend contains min. 50 (min. 65) wt.% chlorinated rubber, esp. chlorinated polyethylene, and is cured with organic peroxides, metal oxides or amines.

The casein need not exceed 5 per cent and preferably does not exceed 2 per cent by weight of the cellulose content of the viscose.ALSO:Composite products of rubber and artificial silk yarns, such as tyre covers containing plies of artificial silk cord, belting, or hose, are made by applying a vulcanizable rubber composition to an assemblage of yarns formed from viscose containing casein, and vulcanizing by heating. Preferably the casein does not exceed 2 per cent of the cellulose content of the viscose. The yarn may be doubled, cabled, or woven into a fabric before applying the rubber, which may be natural, reclaimed, or synthetic, e.g., a copolymer of butadiene and styrene.

Composite Control Cables and Stabilizing Tendons for Aircraft Applications and Method for Manufacture of Same

Принадлежит: Galactic Co LLC

Control and stabilizing cables and tendons for high altitude aircraft and airships having lightweight, high strength and low CTE are disclosed, along with a method and machine for fabrication of same. The cable is comprised of a fiber prepreg tow encased in a polymer sleeve with one bobbin at each end to facilitate connections. Consolidating the fiber prepreg tow along the length of the cable using high temperature shrink tubing, such as polyvinylidene fluoride (PVDF), allows for eliminating the twisting of the fiber prepreg tow, thus reducing the number of wraps around the bobbins. Eliminating the twists in the fiber prepreg tow also reduces the length of fiber needed, and therefore the overall change in length of the control cable with temperature variations is reduced. Additional cable strength can be achieved by adding and holding significant tension on the fiber prepreg tow by applying weight during the curing process.
