Implementation of composite and recyclable thermoplastic materials for automotive bumper subsystem

Alternative lightweight materials and component manufacturing technologies for vehicle frontal bumper beam

“…A numerical study has been conducted according to the methodology developed in [8,9] in order to explore the possibility of substituting the current metallic bumper beam with E-Glass/epoxy pultruded composite beam. The resulting structures are compared in terms of shape and in terms of energy absorbing capability, comparison is also established with steel normal production solution.…”

“…8 mm, and -through equal bending stiffness approach [9], i.e. for a given thickness and stiffness of the reference material, the thickness to be adopted with the targeted material can be approximately calculated by Eq.…”

Crashworthiness Analysis of Composite and Thermoplastic Foam Structure for Automotive Bumper Subsystem

“…As a key design factor, the material selection process takes the major part of the lightweight design process, since >50% of a vehicle production cost is material cost [39]. Hence, generally, the material selection process shall include the entire design problems and utilise novel materials to produce a cost effective, easily manufacturable and maintainable, recyclable and reliable lightweight vehicle.…”

“…The first approach is the simpler one and allows material substitution without altering the geometry profile of the bumper beam. The second approach needs to calculate the thickness of each proposed material to obtain the same stiffness value as the reference solution [39,40]. The calculated bumper beam thickness for each material type is depicted in Table 6.2.…”

An experimental and finite element study of the transverse bending behaviour of CFRP composite T-joints in vehicle structures

“…Research shows that structural optimization can give up to 7% weight reduction. On the other hand, material replacement, such as using a full aluminium body, can lead to weight reduction up to 50% [3,4]. As an alternative, composite materials have been recently considered as one of key potential candidate solutions to achieve lightweight vehicle structure regardless of its manufacturing cost.…”
