Abstract
An example of a method of manufacturing a component from a composite prepreg includes collecting a specimen from the composite prepreg and quantifying an amount of surface resin of the specimen by submerging the specimen in a container containing a fluid to determine a fluid pickup percentage. Responsive to a determination that the fluid pickup percentage exceeds a predefined threshold value, forming a component from the composite prepreg.
Claims18
A method of quantifying surface resin of a composite prepreg, the method comprising:
- collecting a first specimen from the composite prepreg;
- weighing, for a first time, the first specimen to obtain a dry weight of the first specimen;
- submerging the first specimen in a container containing a fluid;
- removing the first specimen from the container;
- weighing, for a second time, the first specimen to obtain a wet weight of the first specimen;
- calculating a fluid pickup percentage of the first specimen using the dry weight of the first specimen and the wet weight of the first specimen;
- comparing the fluid pickup percentage to a predefined threshold value;
- responsive to a determination that the fluid pickup percentage is greater than the predefined threshold value, classifying the composite prepreg as possessing sufficient tackiness for use;
- and
- responsive to a determination that the fluid pickup percentage is less than or equal to the predefined threshold value, classifying the composite prepreg as possessing insufficient tackiness for use.
