Investigation of Crushing Behavior of Polystyrene Coated Spherical Shaped Aluminum Foams

Abstract

In this study, the crushing behavior of spherically shaped aluminum foam pieces coated with polystyrene and uncoated under compression load was investigated. The spherical shaped aluminum foam parts produced by powder metallurgy with diameters of 8 mm and 10 mm were coated with polystyrene by the injection molding process. The obtained foam elements were then subject to quasi-static compression tests at room temperature with a constant cross head speed of 1 mm/min. According to the experimental results, polystyrene coatings increased the energy damping capacity of the foams by approximately 115% while increasing the density by about 50%.

Polistiren Kaplı Küresel Şekilli Alüminyum Köpüklerin Ezilme Davranışlarının Araştırılması

Abstract

Bu çalışmada, polistiren ile kaplanmış ve kaplanmamış küresel şekilli alüminyum köpük parçaların sıkıştırma yükü altındaki ezilme davranışları incelenmiştir. Toz metalurjisi yöntemi ile üretilen 8 mm ve 10 mm çaplarındaki küresel şekilli alüminyum köpük parçalar enjeksiyon kalıplama işlemiyle polistiren ile kaplanmıştır. Üretilen köpükler daha sonra 1 mm/dak deformasyon hızında oda sıcaklığında yarı-statik sıkıştırma testlerine tabi tutulmuştur. Elde edilen deneysel sonuçlara göre, polistiren kaplamalar köpüklerin enerji sönümleme kapasitelerini yaklaşık % 115 arttırırken, yoğunluğu da yaklaşık % 50 oranında arttırmıştır.
