发明名称 Arresting delamination in composite laminate
摘要 A method of arresting delamination between and within plies of a composite laminate having layers containing a resin without significantly degrading the structural strength of the laminate characterized by emplacing within a plurality of the laminate layers having a resin, at a plurality of respective discrete locations, narrow strips of a tough adhesive having a fracture toughness greater than the fracture toughness of the resin in the respective layers of laminate. The adhesive has a Mode I critical strain energy release rate in the range of 5 inch pounds per square inch or more; for example, about 10 inch pounds per square inch. Also disclosed is a preferred method of constructing the laminate to employ this invention.
