Tensile strength, ultimate—17 psi MPa. Location of exotherm plies may be shifted within the laminate body.

ASTM C582 – 09(2016)

NOTE 7—Table 1 and Table 2 are for reference purposes and do not preclude other laminate-type constructions, such as nonwoven biaxial or unidirectional fabric, which may be agreed upon between the buyer and the seller, or may be added to this speci?

As an alternative, a minimum of two passes of chopped roving minimum? NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment.

This standard is issued under the fixed designation C ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Consolidation of the composite laminate is by rolling.

When such items are required, limits for each shall be agreed upon between the fabricator and the buyer. Roll each ply for thorough wet-out and deaeration. Astm a Astm a Consolidation of the composite laminate is by rolling. No plies may be omitted. E Structural lay-up may be interrupted at intervals long enough to exotherm if required by the laminate manufacturing procedure and 6.

Parte 1 de 2 Standard Specification for Contact-Molded Reinforced Thermosetting Plastic RTP Laminates for Corrosion-Resistant Equipment1 This standard is issued under the fixed designation C ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

C Cut edges must be covered with resin. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Tensile modulus—1 psi MPa.

This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement. Flexural modulus— psi MPa.

In Type II laminates the woven roving is to be laid square, and test specimens are to be cut parallel to the warp rovings.

Pastes shall be made with thixotropic agents.

Additional desirable considerations in choosing a veil for a specific application include: Location of exotherm plies may be shifted within the laminate body. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Table 1 and Table 2 for standard thicknesses. In combination with the cured resin, the surfacing veil helps determine the thickness of the resin-rich layer, reduces microcracking, and provides a nonwicking chemically resistant layer.

For 5 by 4 square weave roving, the approximate relationship is shown in Fig. E Structural lay-up may be interrupted at intervals long enough to exotherm if required by the laminate manufacturing procedure and 6. The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment.
