Abstract

An investigational study was conducted into the tensile and impact behavior of Fiber Metal Laminates by combining 5052 aluminum mesh or2024-T3 aluminum sheets,2.47 N (8.9 oz) or 6.67 N (24 az) ShieldStand® S fiberglass, and Hysol EA 9313 epoxy. Testing was performed under the guidelines of ASTM D3039-00 utilizing an lnstron 8802 Servohydraulic Materials Testing Instrument for tensile tests and ASTM D3763-06 utilizing an Inston 9250 HV Dynatup Impulse Impact Testing System for impact tests. Samples were strained at arate of 2 mrn/min for tensile tests and impacted with enetgies of 10 to 40 J in l0 J increments for impact tests. It was found that the 6.67 N Q4 oz) ShieldStand ® S with 2024-T3 aluminum alloy sheet samples performed best when compared to the other fabricated samples. When compared to GLARE 3 there was a 24.7o/o decrease in ultimate tensile strength with 6.07% decrease in ultimate shain. 6.67 N Q4 oz) ShieldStand® S with 5052 aluminum mesh samples were extremely flexible, had the same density and stress-strain curve shape as the fiberglass/epoxy only samples, but behaved like a fiber metal laminate when impacted. Though not as strong when compared to GLARE 5, this material can be used advantageously to create complex shapes and is more cost effective to manufacture.
