摘要:
A method of manufacturing fibre-reinforced plastic articles out of prepregs, prepregs for the manufacture of fibre-reinforced plastic articles and fibre-reinforced plastic articles manufactured by such method. The prepregs contain glass-fibre mats having a fiber length of preferably 4 to 30 mm and a curable resin having a preferred viscosity in the range between 100 and 100 000 Ns/m.sup.2. The prepregs are shaped in a mold by vacuum forming and are cured by UV-light.

摘要:
An improved process for molding fiber-reinforced articles and in particular, those articles which are formed from monofilaments such as metal fibers and processed mineral fibers of the slag type. The fiber-containing molding composition is enclosed in a restraining means, such as a bag, and placed in a mold and formed during which time the bag advantageously deteriorates.

ARTICLE AND METHOD OF PREPARING CONTINUOUS GLASS FIBERS INTO A CONTINUOUS BUNDLE FOR THE USE IN FORMING FRICTION CLUTCH FACINGS. PLURAL ROVINGS (EACH CONTAINING MANY THOUSAND INDIVIDUAL CONTINUOUS GLASS FILAMENTS) ARE IMPREGNATED IN A CEMENT BATH, AND, AFTER PARTIAL DRYING, ARE COLLECTED AND CONTAINED IN A CONTINUOUS BUNDLE BY HELICALLY WRAPPING WITH A SOFT METAL WIRE. THEREAFTER THE BUNDLES ARE ADAPTED TO BE SPIRALLY WOUND UPON THEMSELVES INTO DISC-LIKE FORMS AND CURED UNDER HEAT AND PRESSURE TO DEFINE A FRICTION CLUTCH FACING.
摘要:
A friction material, such as a clutch facing, formed of continuous bundle of parallel continuous glass fibers spirally or randomly wound upon themselves in the form of an annular disc impregnated with heat curable cement and having brass wires helically disposed around the bundles.

Providing blanks from a fibre web includes removing the blanks from removal regions and depositing the blanks in at least one deposit element. The blanks are then removed from the deposit elements in accordance with a sequence predefined by a layer-by-layer construction of a workpiece. The blanks that are individually removed from the removal regions are stacked on top of one another in the deposit elements in a sequence that corresponds to a layering sequence of the blanks in the workpiece. The blanks are then successively removed individually from the deposit elements in a sequence that is reversed with respect to the layering sequence of the blanks in the workpiece and are stacked on top of one another in a storage element before being successively removed from the storage element in the sequence predefined for constructing the workpiece layer-by-layer and inserted into a mould for producing the workpiece.
摘要:
A method of molding a charge (12) during the manufacture of a composite part. The method comprises: placing the charge and a diaphragm (4) on a male tool, the charge having a first part (12a) which is positioned above a top of the male tool (2) and a second part (12b, 12c) which projects to one side of the maletool; and progressively deforming the second part of the charge against a side of the male tool by applying a pressure difference across the diaphragm and stretching the diaphragm over the male tool as the pressure difference is applied. The diaphragm has a tensile modulus in the plane of the diaphragm which is greater than 5 MPa. Optionally a support membrane may be positioned on a opposite sides of the charge. In the case where a support membrane is used, then the diaphragm has a stiffness in the planeof the diaphragm which is higher than the stiffness of the support membrane in the plane of the support membrane.
摘要:
There is disclosed bagging apparatus (20) for bagging a pre-form (12) for a composite component on a tool (10), the apparatus (20) comprising: a bag dispenser (22) having a store (28) for a tubular vacuum bag (30); and a bag guide (36). In use, a length of tubular vacuum bag material (30) can be drawn from the store (28) radially outwardly over the bag guide (36) and over the tool (10) to form a tube around the pre-form. There is also disclosed a method of bagging a pre-form (12) for a composite component on a tool using the bagging apparatus (20).
