Abstract
A vacuum molding-compatible mat including about 10 weight percent to about 99 weight percent glass monofilaments having a mean average length ranging from about 5 to about 150 millimeters and coated with a filament coating composition which is compatible with a thermosetting matrix material for forming a vacuum molded composite; and glass fiber strands having a mean average length ranging from about 5 to about 150 millimeters and coated with a strand coating composition which is compatible with the thermosetting matrix material for forming the vacuum molded composite; wherein the mat has a mat surface weight greater than about 200 grams per square meter, the glass monofilaments and glass fiber strands are essentially uniformly distributed throughout the mat and at least a portion of the glass monofilaments are entangled with at least a portion of the glass fiber strands.
