Cm. Stellman et al., MULTIVARIATE RAMAN IMAGING OF SIMULATED AND REAL-WORLD GLASS-REINFORCED COMPOSITES, Applied spectroscopy, 50(5), 1996, pp. 552-557
A Raman imaging system has been used to investigate chemical and physi
cal homogeneity in interstices of glass-reinforced composites. A proto
col for monitoring chemical and physical spatial variations via multiv
ariate statistics has been developed with the use of a simulated compo
site which provides a well-defined system of known chemical compositio
n and curing conditions. Finally, a preliminary study of a ''real worl
d'' glass-reinforced composite is presented.
