METHOD FOR EVALUATING DEVIATED DISTRIBUTION OF RESIN AND METHOD FOR PRODUCING COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating deviated distribution of a resin in a short time while suppressing the scattering of the evaluation result by different operators. SOLUTION: A B-stage composite material A produced by impregnating a woven or nonwoven fabric substrate 1 with a resin varnish 2 and drying the varnish is subjected to an arbitrary energy and the warpage of the composite material A is measured. The evaluation of the warpage of the composite material A can be carried out without expanding the extremely small cross-section or measuring the amount of the resin in the extremely small cross-section.
