Glass fibre—reinforced polypropylene GF/PP

In addition, the external cross-sectional shape must be rectangular with width 250 mm and depth up to 40 mm, and the weight should be as low as possible. It is proposed to manufacture the new product as an extruded hollow box section, reinforced if necessary by longitudinal webs (see the box section in Figure 8.16). The chosen material is short glass-fibre reinforced polypropylene (GF-PP) with properties given below. 

This paper presents an industrial project where finite element analysis was used to prove that was possible producing gas pressure vessels based on a hybrid solution, consisting on a steel liner wrapped with a glass fibre reinforced polypropylene (GF/PP) filament winding...
