FIBRE REINFORCED PLASTICS STRUCTURES

摘要

An air permeable sheet-like structure comprising 20% to 60% by weight of reinforcing fibers having a high modulus of elasticity (as herein defined), and being between about 7 and about 50 millimeters long, and 40% to 80% by weight of wholly or substantially unconsolidated particulate plastics material, and in which the fibrous and plastics components are bonded into an air permeable structure.
