Fields like aerospace and automobiles are always in need of lighter materials with good strength. Conventional materials do not satisfy these requirements. Many structural parts used in aerospace and automobiles field are of complex shapes which can be manufactured by forming processes. Therefore use of polymer matrix composites having light weight with good process ability, in these field is increasing. For forming of polymer matrix composites it is important to understand the effect of different design and processing parameters on formability of polymer matrix composites. The present paper illustrates the drawing analysis of polymer matrix composites. Composites sheets were made with the nettle fiber, woven glass fiber and random glass fiber as reinforcement in with thermoplastic (polypropylene and polyethylene) and thermosetting (epoxy) matrices. These polymer matrix composites were fabricated on the compression molding machine and along with the hand lay-up process. The drawing process was carried out on the polymer matrix composites with the experimental set up. Parameters used for investigation are punch shape, thickness of sheet, different fiber material and different polymer matrices. Influence of these parameters has been investigated with respect to average failure load and drawing limit measured during the drawing operations. Results indicate that the failure load of woven glass fiber reinforced composite at varying thickness viz. 1mm, 2mm, 3mm in 5 seconds and 10 seconds have far better load carrying capacity in comparison to the random glass fiber and nettle fiber with all type of used matrices based composites with the chamfered tool.
