“…Polyolefin such as PP has low surface energy that results in weak bonding with aluminum. 24,25 PP has a surface energy of 27 mN/m, 26 that is slightly higher than that of Teflon (15 mN/m), 27 a material that is well known for its non-stick characteristic. The bonding between aluminum and PP or its matrix composite has been reported to be minimal without any treatment.…”

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.

In this study, aluminum alloyAA6061-T6 was joined by a hot press process with three types of material; polyamide PA 6.6 (nylon), 1% carbon nanotube/PA6.6 and 30% carbon fiber/PA6.6 composites. Three parameters were considered in the hot pressing; temperature (180, 200 and 220°C), pressure (2, 3, 4, 5 and 6 bar) and time of pressing (1, 2, 3, 4 and 5 minutes for 200ºC, and 0.25, 0.5, 0.75, 1 and 1.25 minutes for220ºC). Applied pressure has great effect on shear strength of the joint, corresponding to bonding time and temperature. Maximum shear strength was 8.89MPa obtained for PA6.6 at bonding conditions of 4 bar, 220ºC and 0.75 minute. For 30% carbon fiber/PA6,6 shear recorded was 8MPa at 4 bar, 220°C and 1 minute, while 1% carbon nanotube/PA6.6 was registered at 8MPa at 4 bar, 220ºC and 0.75 minute. Mechanical interlocking of polyimide in anodizing surface is 8μm approximately. The melting point and glass transmission temperature of polyimide and composites are decreased after hot pressing.
