In this paper, advanced pore morphology (APM) foam elements are combined with thin-walled circular steel pipes by epoxy-bonding and epoxy foam-bonding processes to prepare composite circular pipes. The direct epoxy-bonding process using epoxy resin refers to coating the surface of APM spheres, whereas the epoxy foam-bonding process involves the mixing of the epoxy resin with the epoxy foaming agent and then coating the surface of APM spheres with this mixed epoxy resin. The compression performances and energy absorption performances were analyzed by quasistatic compression tests. Results indicate that the different bonding modes change the deformation mode of the specimen under compression. The epoxy foam-bonding APM composite pipe has a higher compression load level than the epoxy-bonding APM filled pipe. The epoxy foam-bonding APM composite pipe is superior to the epoxy-bonding APM composite and thin-wall hollow pipe. Hence, the combination of foaming and bonding of epoxy can be used as a new filling process for APM fillers.
Highlights
Reduction of vehicle weight is the key to enhance fuel efficiency, and different foam sandwich panels and foam-filled structures have been researched and designed for vehicles [1]
advanced pore morphology (APM) [5,6,7,8,9,10,11,12,13,14] has become a hot topic of research. e APM element is an aluminum foam sphere with a closed-pore structure of 2–15 mm diameter and a complete nearlyspherical surface, which can be prepared by the modified powder-compacting foaming (PCF) method [2, 5, 6]. e geometric structure of the APM element is easy to replicate, and its uniform mechanical and physical properties are almost consistent and it can ensure stability of the filled structure and its performance
Two different filling processes were adopted: in one process, the direct bonding used epoxy resin and the other process used the epoxy resin combined with a foaming agent. is paper studied the deformation modes under quasistatic compression. e obtained load-strain
