ABSTRACT
The crystal structure of aliphatic nylons has been widely investigated. The characteristic phenomenon common to all nylons is the presence of amide groups in the main chain. The main influence on the structure of nylons is the creation of hydrogen bonds. The hydrogen bonding between amide groups is essentially complete in crystalline and also amorphous phase of nylons. The crystalline structure of polymers is mainly investigated with the help of X-ray diffraction. The crystal structure determination includes the determination of the relative positions of atoms in a molecule, and positions and orientations of molecules in a crystal lattice. Reinforcing carbon and glass fibers nucleate a columnar structure of nylon 6 at their surface. The morphology of this structure is different around the carbon and the glass fibers and also around the differing types of the carbon fiber. Crystalline polymers undergo decisive changes in their morphological structure and their properties while being deformed up to high strains.
