Laminate
A product made by bonding together two or more layers of material or materials. Primarily means a composite material system made with layers of fiber reinforcement in a resin. Sometimes used as a general reference for composites, regardless of how made. Examples of usage laminate consumption by market, compression-molded laminate.

Laminate Orientation
The configuration of a cross-plied composite laminate with regard to the angles of cross-plying, the number of laminae at each angle, and the exact sequence of the lamina lay-up.

Laminate Ply
One layer of a laminated product.

Land
The portion of a mold which provides the separation or cutoff of the flash from the molded article; in the screw of an extruder, the bearing surface along the top of the flights; in an extrusion die, the surface parallel to the flow of material; in a semi-positive or flash mold, the horizontal bearing surface; in a two-piece mold, a platform build up to the split line.

Lay-Up
The reinforcing material placed in position in the mold. The process of placing the reinforcing material in position in the mold. The resin-impregnated reinforcement. A description of the component materials, geometry, and so forth, of a laminate.

Loft
The height of the glass lay-down either dry (as in chopping SMC glass) or wet (as in the height of the glass/resin mixture in a spray-up on the mold before roll-out).

Loom
A mechanical device that interlaces fibers at right angles with varying degrees of weave construction (weight, thickness and design). More modern looms are air jet but rapier and more traditional shuttle equipment is still in use.

Low Profile
Resin compounds formulated for low or zero shrinkage during molding.

Low-Pressure Molding
The distribution of relatively uniform low pressure (200 psi or less) over a resin-bearing fibrous assembly of cellulose, glass, asbestos, or other material, with or without application of heat from external source, to form a structure possessing definite physical properties.
