1、Designation: D 3647 09Standard Practice forClassifying Reinforced Plastic Pultruded Shapes Accordingto Composition1This standard is issued under the fixed designation D 3647; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This practice outlines a method for classifying rein-forced plastic pultruded shapes according to their compositi
3、on.1.2 One objective of this practice is to provide a codificationmeans and descriptive limits for classification.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate s
4、afety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 The definitions of reinforcement material, reinforcementtype, resin type, and filler amount and their respective levelsare described below.NOTE 1As an example, a pultruded shape made
5、from a polyester resinmix with 13 % filler and glass roving reinforcement plus woven tape onthe surface comprising perhaps 4 % of the total would be designated as“GRPF”.2.2 Reinforcement Materials:2.2.1 GFiberglass constitutes 90 % or more by weight oftotal reinforcement.2.2.2 CCarbon fibers constit
6、ute 90 % or more by weightof total reinforcement.2.2.3 OOther fibers constitute 90 % of reinforcement.2.2.4 SSpecial composition not covered above.2.3 Reinforcement Type:2.3.1 RRoving constitutes 90 % of total reinforcement.2.3.2 MMat constitutes 90 % of total reinforcement.2.3.3 CCombinations of ma

Classification3.1 In classifying the reinforced plastic pultruded shapeaccording to composition, four separate aspects of t
9、he compo-sition will be considered.3.2 The composition will be identified by the use of fourcapital letters. The sequential position of each letter will haveparticular significance in describing the composition. In addi-tion, the letter itself will have further specific descriptive value.3.3 The cla
10、ssification method will be based upon the four-letter code in which each position of this code will have thefollowing significance:3.3.1 Reinforcement MaterialThe first letter in the com-position code will identify the reinforcement material utilized.3.3.2 Reinforcement TypeThe second letter in the
11、codewill describe the type of reinforcement material employed.3.3.3 Resin TypeThe third position in the code willdescribe the type of resin employed.3.3.4 Filler AmountThe fourth and last position in thecode will define relative amount of filler employed.1This practice is under the jurisdiction ofAS
