1. A method of making a fiber composite member, comprising:
(a) forming wrapped flat members of fiber permeated with a resinous material,
b) wrapping said wrapped flat members to form a tubular member portion, said tubular member portion having first and second ends;
c) effectively placing a foam plastic forming material comprising capsules filled with heat expandable material, said foam plastic forming material being positioned within said tubular member portion formed by said wrapped flat members;
d) substantially closing the ends of said tubular member portion comprising said wrapped flat members to define a substantially closed bladder,
wherein;
e) said closed bladder is introduced into a mold,
f) said tubular member portion containing said foam plastic forming material is heated to cause said foam plastic forming material to expand and form a foam plastic and apply pressure sufficient to form a fiber composite member,
g) said resinous material is hardened to form said fiber composite member, and
i) said foam plastic forming material has an expansion ratio of greater than 30.
