A method for improving the impact strength of fiber reinforced plastic materials hard at ambient temperatures is described, the improvement comprising introducing particulate metal in the form of deformable particles of about 2-20 mu m thickness and having a length of about 10-20 times the thickness, the metal particles constituting about 10 to 80% and preferably about 20 to 50% by weight of the composition, and said particles being in contact with each other, and the composition containing a fiberglass mat of about 300 g/m2, whereby the impact resistance of the composition is rendered many times greater than the additive impact resistance imparted by either the reinforcing fibers or deformable metal particles alone. |
