3.1

preimpregnate

prepreg

material in thin sheets of tows, tape, fabric, or mat impregnated with resin ready to be moulded, and cured if thermoset based

Note 1 to entry: It may be stored before use (normally refrigerated for thermoset based systems).

Note 2 to entry: Used as a generic term in this document to refer to an intermediate product requiring application of pressure and/or heat to form the final product.

3.2

compound

intimate admixture of a polymer or polymers with other ingredients such as reinforcements, fillers, plasticizers, catalysts and colorants ready to be formed, and cured if thermoset based

3.3

preform

dry fibre preform suitable for infiltration by the matrix, normally thermoset based, to provide the final material

3.4

batch

quantity of material formed during the same process and having identical characteristics throughout based on a single supply of fibres, matrices and other additives

3.5

manufacturing run

single manufacturing process for test plates run by a single operator at a single time

3.6

plate and specimen coordinate axes

1-axis (or direction) where the material contains a known axis of preferred fibre orientation (e.g. dominant fibre direction for unidirectional prepregs)

Note 1 to entry: For materials prepared as test plates, the in-plane direction transverse to the 1-axis is defined as the 2-axis. Where any direction of preferred orientation is not known, the 1-axis is taken as the production direction of the composite or the reinforcement (e.g. warp directions for fabrics).

Note 2 to entry: For fully unidirectional materials, specimens cut parallel to the “1”-direction, results are identified by the subscript “11” (e.g. E11). Similarly, for specimens cut parallel to the “2”-direction are identified by the subscript “22” (e.g. E22). For multidirectional laminates, mats and fabrics, results are identified by the subscripts “XX” and “YY” for specimens cut parallel to the X and Y directions respectively. The X, Y and Z coordinate system for any material are equated to the “1”-, “2”- and “3”- directions.

3.7

A-basis design allowable

statistically-based material property with a 95 % lower confidence bound on the first percentile of a specified population of measurements

Note 1 to entry: It is also a 95 % lower tolerance bound for the upper 99 % of a specified population.

3.8

B-basis design allowable

statistically-based material property with a 95 % lower confidence bound on the tenth percentile of a specified population of measurements

Note 1 to entry: It is also a 95 % lower tolerance bound for the upper 90 % of a specified population.
