Abstract
A thermoplastic membrane composite comprising (i) a planar thermoplastic body having first and second opposed planar surfaces; (ii) a fabric backing fixedly attached to said first planar surface thereby forming an interface between said thermoplastic body and said fabric backing; and (iii) expandable graphite disposed at or near the interface.

A thermoplastic membrane composite comprising:
- (i) a planar thermoplastic body having first and second opposed planar surfaces;
- (ii) a fabric backing fixedly attached to said first planar surface thereby forming an interface between said thermoplastic body and said fabric backing;
- and
- (iii) expandable graphite disposed at or near the interface.

A process for forming a thermoplastic membrane composite, the process comprising:
- (i) extruding a first thermoplastic layer;
- (ii) extruding a second thermoplastic layer;
- (iii) positioning a reinforcing fabric between the first thermoplastic layer and the second thermoplastic layer;
- (iv) providing a fabric backing;
- (v) applying expandable graphite to a first planar surface of the fabric backing;
- (vi) positioning the first planar surface of the fabric backing adjacent to a surface of the second thermoplastic layer opposite the reinforcing fabric to thereby sandwich the expandable graphite between the fabric backing and the second thermoplastic layer;
- (vii) laminating the first thermoplastic layer to the second thermoplastic layer to thereby sandwich the reinforcing scrim therebetween;
- and
- (viii) thermally bonding the second thermoplastic layer to the fabric backing.
