Abstract
A structure or laminate comprising a fibrous reinforcement material and a reinforcement resin material are described, wherein the structure or laminate further comprises a tack material, the tack material increasing the surface tack of the structure or laminate over a tack temperature range of from −10° C. to 50° C. in comparison to the original surface tack of the structure or laminate in the absence of the tack material over the same tack temperature range.
Claims21
A structure comprising a fibrous reinforcement material and a reinforcement resin material which provides a surface having an original surface tack wherein the structure further comprises a tack material located on said surface, said tack material comprising a surface having a surface tack wherein the surface tack, over a tack temperature range of from −10° C. to 50° C. is greater than the original surface tack over the tack temperature range and wherein said tack material comprises a porous sheet material impregnated with a polymer material.

A method for increasing the surface tack of a structure comprising the steps of:
- a) providing a structure comprising a fibrous reinforcement material and a reinforcement resin material, said structure having a surface with an original surface tack;
- and
- b) applying a tack material to the structure or laminate to form a surface having a surface tack wherein said surface tack is greater than said original surface tack over a tack temperature range of from −10° C. to 50° C. and wherein said tack material comprises a porous sheet impregnated with a polymer material.
A tack material comprising a polyester veil and a polymer material comprising rubber and phenoxy powder OF a woven phenoxy based grid.
