摘要:
For producing a joined-together fiber composite component in which mutually adjacent regions (5, 6) are constructed in different ways but are cured in a joint thermal treatment, arranged between the regions is a transitional film (8), which has a composition that differs from the compositions of the matrices of the two adjacent regions (5, 6) and which spatially separates the two adjacent regions (5, 6) in the joint thermal treatment but enters into permanent bonds with the matrices of the two adjacent regions (5, 6). The fact that the transitional film (8) is vacuumtight means that one adjacent region (5) can first be formed independently from a preform (9) and enclosed with the transitional film (8), thereby bounding certain portions, and be evacuated and infiltrated with resin (22) on its own, and the other adjacent region (6) can be formed from a prepreg (2). Following this, the two adjacent regions (5 and 6) are brought together and joined to each other, the other adjacent region (6) being sealed and the other adjacent region (6) being evacuated during the subsequent joint thermal treatment for the removal of excess air.
摘要:
A carrier for connecting a window pane to a window lifter including retaining arms which are located to each side of the lower edge of the window pane. At least one of these retaining arms has a recess in which a window bolt can engage to connect the window pane to the carrier. At least the upper part of at least one retaining arm is resilient. One retaining arm has a retaining area formed as a horizontal oblong guide and the other retaining arm has a fixing area which is resiliently attached to the carrier for horizontally urging the window bolt as the bolt moves with respect to the carrier within the horizontal guide.
摘要:
A fiber composite component comprising at least two, first and second partial elements (1, 2) bordering one another, each having a fiber structure (3, 4) and different matrix systems which respectively embed the fiber structure (3, 4) and cure differently from a liquid state, can be produced with an increased stability of the joint between the two partial elements (1, 2) in that first the matrix system of the first partial element (1) is liquefied and thereby penetrates irregularly into the region of the bordering second partial element (2), in that subsequently the matrix system of the second partial element (2) is liquefied and in that the matrix systems are cured. The forming of the irregular boundary surfaces causes an intermeshing or interlocking of the matrix systems with one another, whereby a boundary surface (5) with an increased shear strength is created.Alternatively, the first partial element is consolidated with a fiber structure (102a) unwetted by the matrix system (103) while leaving a transitional region (104), intended for adjoining to the second partial element (105), and subsequently the second partial element (105) is consolidated once the matrix system (106) of the second partial element (105) has penetrated into the transitional region (104) of the first partial element (101).
摘要:
A fiber composite component comprising at least two, first and second partial elements bordering one another, each having a fiber structure and different matrix systems which respectively embed the fiber structure and cure differently from a liquid state is produced by liquifying the matrix system of the first partial element so that it either penetrates irregularly into the region of the bordering second partial element or leaves an unwetted region in the first partial element adjacent the second partial element, and subsequently liquifying the matrix system of the second partial element so that it can be cured abutting the irregular boundary surfaces of the matrix system of the first partial element. The intermeshing or interlocking of the matrix systems with one another and the fibers increase shear strength.
