“…First studies of the rotational molding process have already been conducted and a rough feasibility of the process could be demonstrated as both fiber volume content and geometric fidelity are satisfactory [4,14]. Therefore, the objective of this paper is to evaluate the mechanical strength and the energy absorption during failure of the intrinsically manufactured FRP-metal joint.…”

An innovative production processes for manufacturing rotationally symmetric FRP-metal components, such as drive shafts or tie rods, is the rotational molding process. In the course of this process, a dry fiber preform and metallic load-introduction elements are inserted into a two-piece mold and subsequently clamped into a spindle. The matrix is injected directly into the rotating mold. Due to the arising centrifugal forces, the preform is impregnated and the component cures under rotation. In comparison to conventional joining processes, such as adhesive bonding or bolt connections, the metallic components as well as the FRP part are intrinsically joined during the forming process. A downstream joining process is not required. The joint is based either on the adhesive property of the matrix system or on a form-fit geometry with undercuts. The paper addresses the production and tensile testing of tie rods. Different rod geometries and different surface treatments, including sandblasting, knurling, and arc spraying, are compared and evaluated.

“…Due to centrifugal forces, the dry fibers are impregnated (see Figure 2). The radial impregnation takes place before the axial overlap area is impregnated [14]. To obtain a pore-free FRP structure, ventilation holes are drilled into the metallic load introduction elements as shown in Figure 1 and Table 1.…”

“…Conventional concepts like screw connections [1] or rivet joints [2,3] often induce undesired pre-damage within the composite, while the integration of additional adhesives increases the complexity of the manufacturing process [4]. Interlocking non-destructive approaches represent a suitable alternative [5][6][7], where the connection is created during a hybridization step. All mentioned approaches exhibit load-bearing interfaces, where failure typically initializes.…”

The application of hybrid composites in lightweight engineering enables the combination of material-specific advantages of fiber-reinforced polymers and classical metals. The interface between the connected materials is of particular interest since failure often initializes in the bonding zone. In this contribution the connection of an aluminum component and a glass fiber-reinforced epoxy is considered on the microscale. The constitutive modeling accounts for adhesive failure of the local interfaces and cohesive failure of the bulk material. Interface failure is represented by cohesive zone models, while the behavior of the polymer is described by an elastic-plastic damage model. A gradientenhanced formulation is applied to avoid the well-known mesh dependency of local continuum damage models. The application of numerical homogenization schemes allows for the prediction of effective traction-separation relations. Therefore, the influence of the local interface strength and geometry of random rough interfaces on the macroscopical properties is investigated in a numerical study. There is a positive effect of an increased roughness on the effective joint behavior.
