NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples.
Physical and Mechanical Properties 7. Test Method D Surface resin may require the addition of paraffin or may be astmm with overlaid film, as required or approved by the resin producer, to ensure proper surface cure. Pastes shall be made with thixotropic agents. Roll each ply for thorough wet-out and deaeration.
As aztm alternative, a minimum of two passes of chopped roving minimum? 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 ast, as shown in Appendix X2. A thixotropic agent may be added to the resin for viscosity control. It is informational only c528 not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
