Abstract
PURPOSE: To prevent cracking of prepreg and get good prepreg article by using a tool having a recess to upper direction in case that preperg formation material is obtained by impregneting fibrous material with resin and then hardening the letter.
CONSTITUTION: Some filaments 2 supplied from material robing bobbin 1 attached to a spool is transfered to a resin tank 4 filled with resin varnish 5 such as epoxy resin through guide rolls 3, 3' and filaments 2 are controlled to include necessary amount of resin by a squeeze roll 6. If a cracking occures at this stage or possible to ocuure, a tool 7 of rod or roll having an upper recess is passed under a predetermine tension. Control of the tension is made by moving up and down the tool 7 and if cracking is generated after passing through hardening furnace 8, it is repaired by a tool 7'.
