Beschreibung
Zusammenfassung:	A fiber reinforced prepreg comprising reinforcement fibers; particles (D1) and (D2); and a thermosetting resin composition is provided. The resin includes maleimide compound (A), and co-monomer (B). Co-monomer (B) has least one of an alkenylphenol, an alkenylphenoxy, or a diamine group. Particles (D1) are smaller than (D2) and particles (D1) and (D2) are insoluble in the thermosetting resin. Particles (D1) range in diameter from 1 to 10 microns and have a mode on a volume basis from 3 to 6 microns and are present from 3 to 12 percent by volume of the thermosetting resin. Particles (D2) range from 10 to 100 microns diameter and a mode of 20 to 60 microns and are present from 1 to 6 percent by volume of the thermosetting resin composition. After cure, at least 90% by volume of particles (D1) and (D2) remain in the prepreg interlayers.
