摘要:
A thin-plate-like flexible carbon plate having flexibility, excellent compressive strength, and even electrical conductivity is provided. A carbon plate 1 is a carbon plate having a thickness of 0.05 to 2.0 mm obtained by compression molding of a mixture of (a) 97 to 80 wt% carbon powder composed of 95 to 30 wt% expanded graphite powder and 5 to 70 wt% graphite powder, and (b) 3 to 20 wt% phenolic resin that do not contain ammonia, wherein a compressive strength is 3 MPa or more, a bending strain is 0.6% or more without a crack, and a contact resistance is 6 mΩ·cm 2 or less.
摘要:
An in-situ polymerized type thermoplastic prepreg is provided, which is excellent in productivity, has tack properties and drape properties that allow easy shaping in a mold, is excellent in handling properties, and allows a molded product obtained by curing to have both mechanical properties as high as those of a thermosetting composite and the features of the thermoplastic composite. An in-situ polymerized type thermoplastic prepreg 1 includes reinforcing fibers 2 and an in-situ polymerized type thermoplastic epoxy resin 3 as a matrix resin. The in-situ polymerized type thermoplastic epoxy resin 3 is cured to B-stage, with the weight-average molecular weight being 6,000 or less, and has tack properties and drape properties at 30°C or less, and the in-situ polymerized type thermoplastic epoxy resin after curing has a weight-average molecular weight of 30,000 or more.
