Abstract

Metallic biomaterials (titanium and titanium alloys) have been widely employed in many load-bearing orthopaedic applications, as they have excellent mechanical properties and corrosion stability. However, soaring problems such as a lack of direct chemical bonding between the implant and host tissues leading to implant loosening still persist. To prevent this problem, surface modifications such as applying hydroxyapatite onto titanium is necessary. The aim of this study is to investigate and to compare the bond strength and apatite induction ability of the hydroxyapatite coated titanium.

Abstract

Indonesia is one of ten countries which the largest wood producer in the world. Wood is one of green materials if it’s compared with concrete and steel material. Wood is renewable material too. The problem of using wood for building construction is less of wood with large section dimension. So, engeenered wood appear to solve this problem. One of engeenered wood types is box beam. Box beam can increase inertia of material if it’s compared to traditional wood beam with same section dimension area. The purpose of this experiment is to know the comparasion about torsional stiffness between wood box beam and wood traditional beam. The result of this experiment show that Beam 1 (T.40.40) or traditional beam have torsional stiffness about 105,90 kg.m/rad. Beam 2 (T.45.45.12) is about 159,69 kg.m/rad. Beam 3 (T.50.50.10) is about 190,22 kg.m/rad. And at last, Beam 4 (T.58.58.8) is about 252,89 kg.m/rad. From the result, there are linier chart relationship between torsional stiffness and ratio of wall thickness and section dimension of box beam (t/a). The aplication of box beam should be developed. We hope box beam can be aplicated by people beacause torsional stiffness of box beam is larger than traditional wood beam exactly.
