Fiber-metal laminates consisting of alternating metal and fiber-reinforced polymer layers have displayed remarkable performance in several engineering applications.This work aims to identify the feasibility of incorporating pineapple click here leaf fiber to partially supersede glass fiber in thermoplastic-based fiber-metal laminates.Fiber-metal laminates made of pineapple leaf/glass/polypropylene/aluminum were fabricated using the hot press molding technique.The tensile, flexural, Charpy impact and quasi-static indentation tests were performed.

The findings indicated that the hybridization of glass with pineapple leaf fibers improved the mechanical properties of the laminates.The results are particularly promising in [G/P/G] laminates in which their tensile and flexural strengths are 38.98% and 20.19% higher than [P/P/P] laminates.

In addition, the Charpy impact strengths of [G/P/G] laminates are also 236.66% and 175.68% greater than those of [P/P/P] laminates.In terms of indentation properties, the maximum indentation forces of [G/P/G] laminates are 16.

71% and 13.76% higher than those of [P/P/P] laminates at indenter diameters of 12.7 and 20.0 mm, respectively.

Interestingly, in-plane and out-of-plane properties of hindigyanvishv.com [G/P/G] laminates were comparable to [G/G/G] laminates.Thus, it is anticipated that the hybridization concept could escalate the utilization of natural fibers as a potential reinforcement for engineering applications.
