Method for detecting ratio and curing degree of resin and curing agent in composite material

The invention relates to the technical field of composite material detection, aims to solve the problem that a detection method in the prior art cannot judge the specific ratio of resin to a curing agent in a composite material, and provides a method for detecting the ratio and the curing degree of the resin to the curing agent in the composite material. Then calculating to obtain a fitting constant lambda in a Di Benedetto empirical relational expression, detecting the composite material with an unknown resin/curing agent ratio, and then calculating to obtain the curing degree alpha of the composite material with the unknown ratio after curing and the ratio of the resin to the curing agent; by adopting the method disclosed by the invention, whether the reason for substandard quality of the composite material is the resin/curing agent ratio problem or not can be reversely deduced; the glass transition temperature of the composite material can be improved by optimizing the proportion; whether the resin/curing
