COMPOSITES OF NOVEL BIODEGRADABLE COPOLYAMIDES BASED ON ADIPIC ACID, 1,6-HEXANE DIAMINE AND L-PROLINE WITH SHORT E-GLASS FIBERS .1. PREPARATION AND PROPERTIES

The current demand for environmentally degradable composites has initi ated the use of novel biodegradable copolyamides reinforced with E-gla ss fibres by using the hand lay-up technique. Differential thermal ana lysis, wide-angle X-ray diffraction patterns and density measurements were employed for the characterization of polymeric composites. The th ermal properties of composites, namely T-g and T-m, were determined us ing differential thermal analysis and dynamic mechanical thermal analy ser measurements. The stress-strain curves and compression strength me asurements were recorded and correlated with the glass fibre, void and amino acid content of the copolymers.
