Abstract
A method of fabricating a composite laminate comprises forming a stack including first and second fiber beds and an interlayer between the fiber beds. The fiber beds are impregnated with matrix resin. The interlayer includes a soluble thermoplastic component on an insoluble component. The method further comprises dissolving the soluble thermoplastic component into the matrix resin to reduce thickness of the interlayer.
Claims20
A method of fabricating a composite laminate, comprising:
- forming a stack including first and second fiber beds and an interlayer between the fiber beds, the fiber beds impregnated with matrix resin, the interlayer including an insoluble component on a soluble thermoplastic component;
- and
- dissolving the soluble thermoplastic component into the matrix resin to reduce thickness of the interlayer.
An article for fabricating a composite laminate, the article comprising an insoluble film having a thickness between 2 and 20 microns, and at least one soluble thermoplastic film bonded to the insoluble film, the at least one soluble thermoplastic film increasing thickness of the article.
An article for fabricating a composite laminate, the article comprising a veil of insoluble discontinuous filaments having soluble thermoplastic coatings.
