Method for determining characteristic parameter e.g. air content of carbon fiber reinforced plastic specimen for aerospace prepreg material, involves recording interaction between specimen and irradiated electromagnetic radiation
Method for determining characteristic parameter e.g. air content of carbon fiber reinforced plastic specimen for aerospace prepreg material, involves recording interaction between specimen and irradiated electromagnetic radiation
A carbon fiber reinforced plastic (CRP) specimen is irradiated with a predetermined spectrum of electromagnetic radiation lying in the range of visible light. The interaction between the specimen and the electromagnetic radiation is recorded in a data record. The characteristic parameter of the specimen is determined from the data record.
