摘要:
Compositions include an aerogel component and have low thermal conductivity. Methods for preparing slurries or composites include, for example combining the aerogel component with a surfactant, binder and other ingredients, such as, for instance, fibers. The compositions can be slurries that can be used in coating applications or self supporting rigid composites.
摘要:
Method for manufacturing an aerogel-containing composite, said method comprising the steps of: providing fibers, at least some of which are first fibers, such as mineral fibers, polymer fibers, cellulose fibers, or other types of fibers, in an amount of from 3 to 80 wt % of the total weight of starting materials, providing an aerogel particulate material in an amount of from 10 to 75 wt % of the total weight of starting materials, providing a binder in an amount of from 1 to 30 wt % of the total weight of starting materials, suspending the fibers in a primary air flow and suspending the aerogel particulate material in the primary air flow, thereby mixing the suspended aerogel particulate material with the suspended fibers, mixing the binder with the fibers and/or aerogel particulate material before, during or after mixing of the fibers with the aerogel particulate material, collecting the mixture of fibers, aerogel particulate material and binder and pressing and curing the mixture to provide a consolidated composite with a density of from 120 kg/m3 to 800 kg/m3. With this method homogeneous composites can be produced.
摘要:
Composites, such as syntactic foams, are described. The composite contains at least one polymer and at least one aerogel. The aerogel is coated with a coating substance to at least substantially prevent the intrusion of the polymer into the pores of the aerogel. Methods of making the composite are also described, as well as uses of the composite.

A fastback for a passenger car is provided with a roof profile and a floor profile in the tail region. The roof profile initially descends from a highest profile point and the floor profile initially ascends from a lowest profile point in a rear axle region. The tail region forms an aerodynamic diffusor having a floor diffusor and roof diffusor. For this purpose, the roof profile features an S-shaped upward curvature toward an upper tail break-away edge and the floor profile features an S-shaped downward curvature toward a lower tail break-away edge. Due to the roof profile and the floor profile, the tail region of the passenger car has a shape with a fish-like profile.

A hydraulic clamping device for axially clamping pieces of radial symmetry has a base body with a longitudinal axis slipped onto a receiving mandrel. An annular piston is floatingly arranged in the base body. A closed circuit hydraulic system for displacing the annular piston relative to the base body toward a piece of radial symmetry to be clamped on the receiving mandrel is provided for securely clamping the piece of radial symmetry on the receiving mandrel. A plurality of compensation wedges arranged at the annular piston have wedge surfaces extending symmetrically to the longitudinal axis of the base body. Adjusting screws that are radially displaceable relative to the longitudinal center axis of the base body are provided for displacing the compensation wedges axially in order to secure the compensation wedges in a clamping position.

The invention relates to a method for manufacturing an insulating composite containing mineral fibers, aerogel and binder. This method implies the step of suspending the fiber webs and aerosol in an air flow thereby disentangling the fiber webs and mixing fibers, aerosol and eventually binder homogeneously. The apparatus described combines spinning of the fibers, collecting them as webs, disentangling the fiber webs in suspended air, mixing the fibers with aerogel and cement as well as pressing and curing the mixture to a consolidated product of density 150 to 800 kg/m3.
