This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement. C Cut edges must be covered with resin. This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement. Astm c wilfredo row Enviado por: Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out. The abbreviation for reinforced thermoset plastic is RTP.
Pastes shall be made with thixotropic agents. Lapped edges of adjacent layers shall be staggered. Tensile strength, ultimate— psi 62 MPa. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. 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.
These products shall be a commercial grade of E-type glass fiber with a sizing that is compatible with the resin.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Tensile modulus—1 0 psi MPa. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Additional desirable considerations in choosing a veil for a specific application include: C — Standard Speci? A number in parentheses indicates asstm year of last reapproval.
NOTE 1—The laminates covered by this speci? Entrapped air or bubbles described are allowed, provided the surface cannot easily be broken with a pointed object, such as a knife blade. However, results of this test may be used as elements of a fire risk assessment that takes into account all the factors that are pertinent to an assessment of the fire hazard or a particular end use. Location of exotherm plies may be shifted within the laminate body.
Laminates shall be qstm according to type, class, and grade: This specification is limited to fabrication by contact molding.
ASTM C582 – 09(2016)
Last previous edition C — 87e1. This abstract is a brief summary of the referenced standard. Roll each ply for thorough wet-out and deaeration. A thixotropic agent may be added to the resin for viscosity control.
Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out. Tensile strength, ultimate—17 psi MPa.
This standard does not purport to address all of the safety concerns, if any, associated with its use. A superscript epsilon axtm indicates an editorial change since the last revision or reapproval.
NOTE 8—The addition of? They are not arbitrarily selected values. A Calculated thickness for design purposes is determined as follows: Tensile strength and tangent modulus of elasticity, flexural strength, glass content, thickness, hardness, chemical resistance, and surface flame-spread classification tests shall be performed to conform to the specified requirements.
This specification is limited to fabrication by contact molding. The resin matrix is applied by various methods, including brush, roller, or spray gun.
