PREPREG AND ITS USE

PURPOSE:To obtain the subject prepreg bondable at low temperature under low pressure and capable of shortening the working time by combining a prepreg obtained by impregnating a specific ethylene polymer in a cloth substrate with a prepreg having plural fluororesin layers. CONSTITUTION:Layers 4 of a...

Zusammenfassung:	PURPOSE:To obtain the subject prepreg bondable at low temperature under low pressure and capable of shortening the working time by combining a prepreg obtained by impregnating a specific ethylene polymer in a cloth substrate with a prepreg having plural fluororesin layers. CONSTITUTION:Layers 4 of a tetrafluoroethylene-hexafluoropropylene copolymer (abbreviated to FEP) or a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer are formed on a cloth substrate 3 and each layer 4 is further laminated with a polytetrafluoroethylene layer 5 (abbreviated to PTFE) and an FEP layer 6 to form the 1st prepreg 1. The objective prepreg can be produced by laminating the 1st prepreg layers on both surfaces of a 2nd prepreg 2 produced by impregnating a PTFE layer 5 in a cloth substrate 3.
