 Does anybody know if there have been investigations by x-ray-scattering
 or small-angle-x-ray-scattering into the molecular structure of spider silk ?
 It is assumed that spider silk resembles that of the silkworm and is therefore
 a composite material made of strands of disordered amino acid chains (polymer 
 matrix) and ordered protein crystalls (F. Vollrath, Scient. Am., March 1992, 
 and others). However, as far as I know, there is no proof for this assumption. 
 If anybody knows more, please let me know. Any suggestions and hints would be
 greatly appreciated.
                        Thanks in advance
