Astm c wilfredo row Enviado por: Workmanship and Finish 9. Current edition approved Oct. Flexural strength, ultimate—2 0 psi MPa. A thixotropic agent may be added to the resin for viscosity control. Tensile strength, ultimate—17 psi MPa. This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement.

Roll each ply for thorough wet-out and deaeration.

Tensile strength, ultimate—17 psi MPa. This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. 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.

NOTE 1—The laminates covered by this c5882 are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. Flexural modulus—1 psi MPa.

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. As an alternative, a minimum of two passes of chopped roving minimum fiber length 1 in.

ASTM C582 – 09(2016)

However, results of this test may be used as elements of a? Consolidation of the composite laminate is by rolling. The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. The abbreviation for reinforced thermoset plastic is RTP. Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out.

Next apply the specified surface mat, rolling so as to draw the resin through the mat for thorough wet-out and deaeration. NOTE 1—The laminates covered by this speci? Consolidation of the composite laminate is by rolling. A number in parentheses indicates the year of last reapproval. Surface resin may require the addition of paraffin or may be sealed with overlaid film, as required or approved by the resin producer, to ensure proper surface cure.

The resin matrix is applied by various methods, including brush, roller, or spray gun. Flexural modulus— psi MPa. Entrapped air or bubbles described are allowed, provided the surface cannot easily be broken with a pointed object, such as a knife blade. The abbreviation for reinforced thermoset plastic is RTP. C — Standard Speci? The resin matrix is applied by various methods, including brush, roller, or spray gun. Roll each ply for thorough wet-out and deaeration. 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.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? D Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added.

Originally published as C — 65 T. A number in parentheses indicates the year of last reapproval. C Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. Gaps are not permitted. In all cases only the current version of the standard as published by ASTM is to be considered the official document. Additional desirable considerations in choosing a veil for a specific application include: Flexural modulus— 0 psi MPa.

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, asym year of last revision. This abstract is a brief summary of the referenced standard. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.

Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out. Lapped edges of adjacent layers shall be staggered. This specification covers f582, thickness, fabricating procedures, and physical property requirements for glass fiber reinforced thermoset polyester, vinyl ester, or other qualified thermosetting resin laminates comprising the materials of construction for RTP corrosion-resistant tanks, piping, and equipment.
