bundle 32 can be handled to some degree without affecting integrity however upon drying the fractured bundle is more difficult to handle accordingly it is preferred to treat the damp fractured bundle with a sizing material that is compatible with the dampening fluid and which increases the cohesiveness of the fiber bundle for example water based epoxies are a preferred coating or sizing material when water is used as the dampening fluid other coatings that are commonly used as sizing materials may be used the sizing material is preferably applied as a mist or fine spray the amount of sizing added is between about 0 3 weight percent to about 3 0 weight percent amounts in the range of about 0 5 to 1 5 weight percent are preferred in general the amount of sizing applied to the bundle will be sufficient to increase the cohesiveness of the bundle so that it can be handled without falling apart while at the same time not saturating the bundle the coated or u201c sized u201d fiber bundle may be dried and then wound onto a spool or otherwise further processed for example as is well known the sized fiber bundles can be woven to form any number of desired fabric structures the fabric structures are impregnated with a suitable polymer resin such as epoxy resin phenolic resin biomaleimides.
