Abstract:
Initiatives of providing biogas onsite are futile without
provision for offsite use. This study aims to compare the
mechanical strength of materials for packaging biogas. To
address the research problem, four materials were
considered for the study, including: low-carbon steel,
Aluminium, High-Density Polyethylene (HDPE) and
fiberglass polyester composite. An experiment was carried
out on each of the materials to find out the yield strength
and ultimate tensile strength. Results indicate that, whereas
steel ranks highest in many strength parameters, including;
tensile strength, yield strength, factor of safety, and stress
carrying capacity; fiberglass polyester composite closely
follows in all measures, and has the highest value of specific strength of all the study materials; with over 58% more weight
saving as compared to steel. This property explains the strength-to-weight ratio of a material; which is a key consideration for
designing light and strong pressurized gas containers.
