This invention relates to a wet-laid sheet material prepared from thermoplastic fibers, graphite particles, reinforcing fibers, and microglass fibers. The sheet material is useful in making compression molded composite plaques, said plaques being thermally and electrically conductive.

Wet-laid sheet material and composites thereof

A process for the production of structural and semi-structural composites formed by compressing planar layers of nonwoven preform materials formed from aqueous blends of reinforcing fibers and thin thermoplastic fluoropolymer flake. The flakes have an irregular periphery with microfibrils extending therefrom, having a Canadian Standard Freeness greater than 800. The planar layers which are unconstrained in the in-plane direction are preconsolidated by heating the layer to above the melting point of the fluoropolymer, the applying pressure normal to the plane of the layer causing the fluoropolymer to flow thus orienting the fibers in the plane of the layer. The composites are useful in applications which require higher strength and/or modulus, and where chemical and/or heat resistance is needed, as in chemical processing.

A blade member for use in a shutter curtain assembly. The blade member is of a given height and has a top, a bottom, a first edge and a second edge. A first semi-cylindrical interlocking portion extends along the first edge. The first portion includes a pair of inwardly-directed tangs which extend from opposite sides of the semi-cylinder. A second semi-cylindrical interlocking portion extends along the second edge and is sufficiently smaller in diameter than the first portion. A second interlocking portion of a succeeding blade member may be slidably inserted into the first interlocking portion. The second portion includes a pair of outwardly-directed tangs which abuttingly engage the inwardly-directed tangs of the first interlocking portion. A series of blade portions are thus interconnected and form a continuous shutter curtain which is selectively unfolded or retracted.

Interlocking shutter curtain assembly

A method for determining the quality of dispersion of glass fibers in a thermoplastic resin preform layer compares the mean characteristic length of the glass fiber bundles in the preform layer to a predetermined value indicative of dispersion of the glass fibers. The thermoplastic resin preform layer characterized by this method comprises a plurality of individual glass fibers and some degree of undispersed glass fiber bundles intimately mixed with a plurality of discrete thermoplastic fibers. The glass fibers are introduced to the mixture having a length of about 1 cm. to about 8 cm. After mixing, some of the glass fiber bundles break up, and some residual glass fiber bundles remain. A preform layer which has acceptable dispersion has residual glass fiber bundles having a mean apparent length of less about 1.365 mm.

A process for forming a self-supporting preform layer of a homogeneous blend of relatively long glass staple length fibers and wettable fine denier staple length thermoplastic filaments wherein a neutral pH aqueous slurry of the glass fibers and filaments are formed into a mat using conventional papermaking equipment. In the preferred process the wettable thermoplastic filaments are dispersed first in the water then followed by the addition of the glass fibers. The self-supporting preform when converted into a molded composite structure results in a substantially void-free structure of individual glass fibers embedded in a thermoplastic resin matrix.
