- the present invention relates to a glass fiber yarn connector.
- a long fiber reinforced plastic in which a thermosetting resin or a thermoplastic resin is used as a matrix resin, and a glass fiber yarn (glass strand) having a long fiber length is disposed as a reinforcing material in the matrix resin.
- the long fiber reinforced plastic is impregnated with a resin in a glass fiber thread drawn from a glass roving by applying a predetermined tension, passed through a die to remove an excess resin, and the amount of attached resin is determined. After adjustment, it is manufactured by curing the resin.
- the glass fiber yarn is a collection of a plurality of glass filaments coated with a sizing agent on the surface, and the glass roving is formed by winding the glass fiber yarn around a core in a roll. There is.
- the supply of the glass fiber yarn is not interrupted.
- the glass roving is manufactured and transported in a state of being wound in a roll around the winding core, but winding the glass fiber yarn too long around one winding core is disadvantageous in terms of production and transportation.
