摘要:
Disclosed is a method and apparatus for the manufacture of a composite article. A composite lay-up is provided having a female radiused portion. The composite lay-up is compressed so as to reduce its thickness. Additional compression is applied to the female radiused portion.The additional compression reduces or substantially eliminates the bridging that might otherwise occur, and achieves a more consistent material thickness around the female radiused portion, and a more consistent and greater fibre volume ratio.

A resilient member (29) for a side bearing includes a first rigi d element (31) extending in a linear direction and having a first end and a second end. A second rigid element (41) extends in the linear direction of the first rigid element spaced from the first rigid element to provide a space between the two. The first end of the second element is displaced along the linear direction away from the first end of the first rigid element. Resilient material (39) fills the space between the first rigid element and the second rigid element with a substantially concave profile (33) connecting the first ends of the two elements. The resilient material includes at least one weakened region (37) along the substantially concave portion thereof as a result of assembly, which is located where the resilient material is subjected to the relatively lower stresses and strains when used in a side bearing.

Methods for bonding metallic structures to thermoplastic and thermoset composite structures are described. The methods include steps for preparing the metallic structure (14) for bonding by knurling a mating surface of the metallic structure and molding a layer of thermoplastic material (50) over the knurled mating surface to produce a bonding surface. To bond a metallic structure (14) to a thermoplastic composite structures (16), the bonding surface of the metallic fitting is consolidated with the thermoplastic composite structure (50). To bond a metallic structure to a thermoset composite structure, a bonding surface is formed on the thermoset composite structure by partially embedding a layer of dry fibre reinforcement in a thermoplastic material layer, coating the exposed dry fiber reinforcement with thermoset resin, and curing the coating dry fiber reinforcement into the thermoset composite structure. The bonding surfaces of the thermoset composite structure and the metallic structure are then fused together by applying heat sufficient to melt the thermoplastic material layers of the bonding surfaces. A resistance heating element (54) is disposed between the bonding surfaces of the thermoset composite structure (16) and the metallic structure to provide the heat required to melt the thermoplastic material layers of the bonding surfaces.
