“…25 It is common that the material is simplified as isotropy based on macro mechanical performances when dealing with the composite issues. 26 Assuming random distributions of fibers, the composite will exhibit isotropic properties, and an equivalent modulus can be obtained in DIGMANT-MF. 25 The Young's modulus of three directions and the equivalent modulus are listed in Table 2.…”

Aiming to the lightweight design of the long glass fiber reinforced thermoplastic (LGFT) composite wheel, this paper constructs the design process and the strength analysis method of long glass fiber reinforced thermoplastic wheel. First, the multi-objective topology optimization under multiple design spaces and multiple loading cases is conducted to obtain the robust structure, where the complicated ribs generated in design spaces are quite distinct from conventional steel or aluminum alloy wheel. The effects of weighting factors of two objectives and three loading cases on the topological results are discussed. And the long glass fiber reinforced thermoplastic wheel including the aluminum alloy insert is also designed in detail based on the concept structure and molding process. The novel metallic insert molded-in is another typical feature of long glass fiber reinforced thermoplastic wheel. Capturing the material anisotropy, the strength performances of long glass fiber reinforced thermoplastic wheel are simulated by using the finite element analysis method. The results show that there is a larger safety margin than the baseline wheel based on the maximum stress failure criterion. The long glass fiber reinforced thermoplastic wheel of 5.59 kg saves 22.3% weight compared to the aluminum alloy baseline. For the increasing requirement of automotive components lightweight design, the method and consideration in this paper may also provide some ways for the design and strength analysis of other carrying structures made of thermoplastic composite.

“…Although mechanical properties (e.g., strength) of strap lap bonding joints can be experimentally determined (Osnes and McGeorge 2005;Wang and Gunnion 2009;Sayman et al 2013), their structural stress distribution cannot be tested or described. Currently, stress distributions in bonding joints can be numerically simulated by the finite element method, thus facilitating mechanical analysis for the design of complicated adhesive structures (Vaidya et al 2008;Lu et al 2013).…”

A design for strap lap bond joints of wood powder/polyethylene composites (WP/PE) was proposed. The effects of combined treatment on surface properties of WP/PE and failure modes of WP/PE bonded by epoxy and acrylic ester were investigated. A finite element model of strap lap bond joints of WP/PE was established based on the elastoplasticity finite element method, and the effects of lap length and adhesive (epoxy and acrylic ester) on stress distributions and comprehensive displacements of strap lap bond joints of WP/PE were investigated. The results demonstrated that the bonding interface roughness of WP/PE was enhanced by the combined surface treatment. Active oxygen-containing functional groups were introduced to the sample surface. The finite element simulation results revealed that the Mises equivalent stress peaks and comprehensive displacements of strap lap bond joints were concentrated in lap zone ends and board connections, the stress distribution was independent of the lap length, and the Mises equivalent stress peaks and comprehensive displacements were independent of the adhesive.

“…14 Aluminum was integrated with glass fiber nylon matrix composite using extrusion–compression molding (ECM), and the hybrid tailcone was able to withstand the high temperature and pressure from firing. 9,15 Due to the different characteristics of the metal and the composite material, weak bonding is normally resulted between the metal and the composite material. The mechanical properties of these metal/polymer matrix composite hybrid materials are highly dependent on the bonding between the metal and the composites.…”

Hybridizing different materials, such as metals and polymer matrix composites, has recently drawn attention as it can produce a unique material that offers advantages from both the metals and the composites. However, the strict surface preparation required, a relatively low production rate, and the resultant weak interface have been the hurdles for this technology. The low surface energy of some polymeric materials, such as polypropylene (PP) and their composites, has posed even more challenges when bonding with metals. This work aims to develop a hybridized PP matrix composite and aluminum with through thickness reinforcements (TTRs) at a high production rate and with minimal treatment. Long glass fiber PP matrix composite (LFT glass/PP) is integrated with aluminum sheet using an extrusion–compression molding process at a rate of 2 minutes per plate. The bonding between these two materials is achieved using the TTRs on the aluminum sheet that provide mechanical locking at the interface. The hybridized aluminum and glass/PP LFT material is evaluated on its performance in lap shear, short beam shear, flexure, and tension. It is concluded that the mechanical locking at the interface provides a lap shear bonding strength of 6.8 MPa, and the hybridized material has significantly improved tensile and flexural modulus as well as strength compared to the glass/PP LFT only. The same approach can be readily extended to hybridizing other polymer matrix composites with metallic materials.
