INTRODUCTION
A Fiber Metal Laminate (FML) is one of a class of metallic materials consisting of a laminate of several thin metal layers bonded with layers of composite material. This material behave much as a simple metal structure, but with considerable specific advantages regarding properties such as metal fatigue, impact, corrosion resistance, fire resistance, weight-savings and specialized strength properties.
FML are a new type of composite. Thin sheets of aluminum are alternated with thin sheets of traditional composite. It becomes a good substitute for metal structures, especially in aerospace and aircraft applications. This is because of its good mechanical properties such as excellent fatigue and impact resistance as well as damage tolerance, without sacrificing low weight.
In this research, short Kenaf fiber was use as reinforcement filler and polypropylene (PP) as a matrix and then laminated with aluminum thin sheet. This research will investigate the nocth strength of the specimen by varying the hole diameter.
RESEARCH OBJECTIVE
The objectives of research are:
i. To determine the notch strength reduction in tension of FML based on Kenaf fiber. This is very important because in real application it is necessary to drill holes into laminates to facilitate bolting or riveting for joining process.
ii. To compare the notch strength reduction with the post impact tensile strength.

perghh..camnie ke idup engineer?
kental2....fenin2..
idup engineer lg susah dr ni.. huahahaa...
tanye pajeri la la qila.. die pon bakal engineer kn...
