E Structural lay-up may be interrupted at intervals long enough to exotherm if required by the laminate manufacturing procedure and 6. B Calculated thickness for design purposes is determined as follows: E Structural lay-up may be interrupted at intervals long enough to exotherm if required by the laminate manufacturing procedure and 6.
NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. Aztm standard is issued under the fixed designation C ; the number immediately following the designation indicates aastm year of original adoption or, in the c5822 of revision, the year of last revision. See Table 1 and Table 2 for standard thicknesses. The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment.

C — Astm c wilfredo row Enviado por: The resin matrix is applied by various methods, including brush, roller, or spray gun.
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?

Lapped edges of adjacent layers shall be staggered. Lapped edges of adjacent layers shall be staggered. This abstract is a brief summary of the referenced standard.
Flexural strength, ultimate—2 0 psi MPa. A surfacing mat is not required unless speci? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Astm a Astm a 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.
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. 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.
D Test Method D Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. 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 specification if they have been fully identified and characterized, as shown in Appendix X2.
This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement.
Your comments are invited either astmm revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Surface resin may require the addition of paraffin or may be sealed with overlaid?
Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out. Flexural strength, ultimate—18 psi MPa. For 5 by 4 square weave roving, the approximate relationship is shown in Fig.
Tensile modulus—1 0 psi MPa. This standard does not purport to address all of the safety concerns, if any, associated with its use. These products shall be a commercial grade of E-type glass fiber with a sizing that is compatible with the resin. When such items are required, limits for each shall be agreed upon between the fabricator and the buyer. No plies may be omitted.
