Abstract
Fiber-reinforced syntactic foam composites having a low specific gravity and a coefficient of thermal expansion of about 9.0.times.10.sup.-6 in/in/.degree.F. (16.2.times.10.sup.-6 cm/cm/.degree.C.) or less are prepared from a mixture of: a heat curable thermosetting resin comprising an uncured polyglycidyl aromatic amine, a polycarboxylic acid anhydride curing agent, and a chosen curing accelerator; hollow microspheres having a diameter of about 5 to 200 micrometers; and fibers having a length less than or equal to 250 micrometers. These composites are useful for forming lightweight structures for space applications.
