摘要:
A curable impact modified epoxy resin mixture suitable for producing high performance composites is composed ofA. an aromatic epoxy compound,B. an amine type curing agent,C. from 10 to 40% by weight of an aromatic thermoplastic oligomer which contains reactive groups, preferably a polyether sulfone, andD. from 0.1 to 10% by weight of a high molecular weight emulsifier, preferably a phenoxy resin, an epoxy resin or a thermoplastic copolymer, which is compatible not only with the epoxy compound A but also with oligomer C.
摘要:
Bismaleimide resin systems and fiber reinforced prepregs prepared therefrom having exceptional toughness are prepared by dispersing into a bismaleimide base resin system preformed functionalized elastomer particles having a T.sub.g of less than 10.degree. C.
摘要:
The incorporation of 2 to 25 .mu.m particles of a limited class of polyimides having appreciable nonaromatic character into heat curable epoxy resin systems significantly increases the toughness of such systems without loss of other desirable properties. These toughened epoxy resin systems are useful in preparing carbon fiber reinforced composites having compression strength after impact (CAI) of greater than 45 Ksi after a 1500 in-lb/in impact.

The incorporation of 2 to 35 .mu.m particles of a differentially soluble engineering thermoplastic into heat curable epoxy resin systems significantly increases the toughness of such systems without loss of other desirable properties. These toughened epoxy resin systems are useful in preparing carbon fiber reinforced composites having compression strength after impact (CAI) of greater than 45. Ksi 310 MPa after a 1500 in-lb/in impact.
摘要:
The subject invention pertains to toughened thermosetting resin systems useful as structural adhesives and as matrix resins for thermosetting fiber-reinforced prepregs. These toughened resins employ a most minor amount of functionalized elastomeric particles having a T.sub.g of 10.degree. C. or below dispersed in a thermosetting base resin system.

An electrical and/or hybrid motor vehicle device includes a charging device for the charging of an accumulator device. The charging device includes a first charging unit with a connector element for the charging of the accumulator device, which is provided for energy transfer by means of contacts. The charging device also includes a second charging unit with an energy transfer unit for the charging of the accumulator device, which is provided for a contactless energy transfer. The charging device has a charging electronic system, which is provided at least in part as an integral construction with the first and second charging units.
摘要:
A camera arrangement for a vehicle includes a camera and an electrical conductor structure. The camera is separated from a pane which divides an outside region from an inside region. The camera is in the inside region and is pointed at a portion of the pane such that the camera has a viewing detection region through the pane. The conductor structure forms a device and is on the portion of the pane within the viewing detection region of the camera whereby the camera and the device use the same portion of the pane for their operations.
摘要:
A vehicle seat, particularly a commercial-vehicle seat is provided with a scissor-type stand (3) which is able to vibrate and which is provided with a top frame (7), two first rocker arms (8a) and two second rocker arms (8b), which intersect in pairs at a scissor axis (10) extending in a transverse seat direction (y). The first two rocker arms (8a) are connected with one another at one end via a transverse tube (18) which extends in the transverse seat direction (y) and are pivotably mounted on the top frame (7) and able to vibrate in the longitudinal seat direction (x) via a bearing mechanism (20). The transverse tube (18) can be locked with the top frame (7) via at least one locking device (31).
摘要:
A vehicle seat (1), in particular a commercial vehicle seat, is provided with a scissor-type stand (3) with a seat frame (10) that is articulated thereto by a pivoting axis (B), the seat frame being able to incline in relation to the scissor-type stand (3), and a back rest (20) that is attached to the seat frame (10). The seat frame (10) is articulated directly to the scissor-type stand (3) and is connected in an articulated manner to the scissor-type frame (3) by at least one three-hinged element.
摘要:
In a method for referencing the position of an actuating element of a functional unit, in particular of a clutch in the drivetrain of a vehicle, the attainment of a reference position of the actuating element is assessed for plausibility in that it is checked whether a variable which can be applied to the actuating element varies in a predetermined way in a predetermined spacing of the position of the actuating element from the reference position.
