That is correct. The coring materials do have grooves, depressions,
kerfs, etc to increase the amount of the surface area exposed to resin.
If you take a hole saw to a cored layup and examine the plug, you will
see resin within the core layer (in the channels and passages where it
is supposed to be). Resin can flow laterally across the core.



Next, speaking about the various layers of mat used in infusion molding
compared to roller lamination, Ms. Smith observed:

It can't be the "same" because normal cloth & mat won't flow the
resins
freely enough, the problem which you unwittingly admit is that uniform
wetout is an issue & excess resin in glass is almost as damaging the
finished laminate as not enough resin

So then it is your opinion that vacuum bag molding can *never* be done
correctly because it has to be differently from other methods? If
everybody thought that way, we wouldn't even have fiberglass boats- let
alone be arguing about laminate methods.

None of her points beyond here were expressed without personal insult,
so I'll not dignify any of them with a reply.


Postings with personal insults? Something you are getting quite good at
lately Chuck, sometimes reaching as low as one would expect from a 2nd
grader, certainly not from an adult as you say you are.
