Structural Adhesive Adhesive used for transferring required loads between adherends exposed to service environments typical for the structure involved. Breather A loosely woven material, such as glass fabric, which serves as a continuous vacuum path over a part but does not come in contact with the resin. The agent applied to fiber mat or preforms to bond the fibers before laminating or molding. Terms that help identify problems in the layup process, or the strength and properties of your components. The treatment contains ingredients that provide surface lubricity and binding action but, unlike a finish, contains no coupling agent.

Roving A number of yarns, strands, tows, or ends collected into a parallel bundle with little or no twist. Limitations. Scrim A low-cost reinforcing fabric made from continuous filament yarn in an open-mesh construction. Adhesive can be in film, liquid, or paste form. See also separator. Used to control the thickness of a press-molded part. Now called deflection temperature. Glass Transition Temperature (Tg) The approximate midpoint of the temperature range over which the glass transition takes place; glass and silica fiber exhibit a phase change at approximately 955°C (1750°F) and carbon/graphite fibers at 2205°C to 2760°C (4000°F to 5000°F). Hybrid A composite laminate comprised of laminae of two or more composite material systems, e.g., glass and carbon. A composite number is a positive integer that has at least one positive divisor other than one or itself. The layers that make up a stack. Dry Lay-Up Construction of a laminate by the layering of preimpregnated reinforcement (partly cured resin) in a female mold or on a male mold, usually followed by bag molding or autoclave molding. Normally, these stresses originate when different components of a wet lay-up have different thermal coefficients of expansion. Applicable to those materials whose change upon heating is substantially physical rather than chemical and that in the softened stage can be shaped by flow into articles by molding or extrusion. ... A number which has more than two factors is called a composite number. Coupon Usually, a specimen for a specific test, as a tensile coupon. A term often used when the relationship of stress to strain does not conform to the definition of Young's modulus.

Balanced Laminate A composite laminate in which all laminate at angles other than 0° and 90° occur only in + pairs (not necessarily adjacent) and are symmetrical around the centerline. A composite number has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number. Learning Center - Glossary of Terms in Composites. Unless an acid is extremely concentrated, the equation is simplified by holding the concentration of water as a constant: The acid dissociation constant is also known as the acidity constant or acid-ionization constant. Meaning of Index […] The temperature at which increased molecular mobility results in significant changes in the properties of a cured resin system. A related value is pKa, which is the logarithmic acid dissociation constant: Ka may be used to measure the position of equilibrium: Ka may be used to predict the strength of an acid: Ka is a better measure of the strength of an acid than pH because adding water to an acid solution doesn't change its acid equilibrium constant, but does alter the H+ ion concentration and pH. Bleeder Cloth A nonstructural layer of material used in the manufacture of composite parts to allow the escape of excess gas and resin during cure. Sandwich Construction A composite composed of lightweight core material (usually honeycomb or foamed plastic) to which two relatively thin, dense, high-strength, functional, or decorative skins (also called faces) are adhered. A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Molding Constructing a part within a mold. Resin-Transfer Molding (RTM) A molding process in which catalyzed resin is transferred into an enclosed mold into which the fiber reinforcement has been placed; cure normally is accomplished without external heat.

Honeycomb may also be metallic or polymer materials in a rigid, open-cell structure. To solve the problem, first, write the chemical equation for the reaction. Cross Laminated Material laminated so that some of the layers are oriented at various angles to the other with respect to the laminate grain. Example: 6 can be made by 2 × 3 so is NOT a prime number (it is a composite number).

Isotropic Having uniform properties in all directions. It also applies to woven fabrics having more than one type of fiber. Unbound An area within a bonded interface between two adherends in which the intended bonding action failed to take place, or where two layers of prepreg in a cured component do not adhere to each other. Volatiles Materials, such as water and alcohol, in a sizing or a resin formulation, that are capable of being driven off as a vapor at room temperature or at a slightly elevated temperature. The group of filaments is considered an "end" or strand before twisting, a "yarn" after twist has been applied. However, the Shor’s algorithm does have a fraction that uses classical algorithm to factorize the composite number given a special modular exponential period … Definition: A composite number is an integer than is composed of integer factors. The ability to resist partition of itself. Usually assigned a style number.

It is used in immediate contact with the lay-up during the curing process to transmit normal pressure and provide a smooth surface on the finished part. Pressure Bag Molding A process for molding reinforced plastics in which a tailored, flexible bag is placed over the contact lay-up on the mold, sealed, and clamped in place. So 15 is a composite number. Not a recommended practice, because the resin will receive less pressure, which can result in voids.
