5、R2009 Glossary of Fiberboard Terminology RATIONALE J947 has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE This information report presents the terminology and definitions as used in the fiberboard industry. 2. REFERENCES There are no referenced publications specified herei
6、n. 3. DEFINITIONS See Scope. 3.1 Fiberboard 3.1.1 Description A broad general term for fibrous structures produced on any of the several types of fiber forming machines. The primary composition of these boards is normally refined cellulosic or matted wood fibers which may or may not be supplemented
7、by the use of synthetic materials or chemical additives. The manufacture of fiberboards normally involves the formation of a wet web of suspended fibers, which is subsequently pressed, dried, and often calendared or laminated to develop desired end use properties. 3.1.2 Physical/Mechanical Propertie
8、s Except for the characteristic fibrous structure, the physical properties may vary over a wide range. The term fiberboard is normally limited to thicknesses of 0.23 mm (0.009 in) or above. 3.1.3 Applications The normal uses for this material include nearly all automotive applications where fibrous
9、board structures are specified. SAE INTERNATIONAL J947 Reaffirmed JAN2014 Page 2 of 5 3.2 Fiberboards Classified by Manufacture 3.2.1 Hardboard 3.2.1.1 Description A generic term for a sheet manufactured primarily from interfelted lignocellulosic fibers (usually wood) consolidated under heat and pre
10、ssure in a hot press to a density of 880 to 1041 kg/m3(55 to 65 lb/ft3) (specific gravity 0.9 to 1.0) or greater, and to which other materials may have been added during manufacture to improve certain properties. 3.2.1.2 Physical/Mechanical Properties This material is generally a stiff grade of fibe
11、rboard with isotropic physical properties. 3.2.1.3 Applications The normal uses for this material include nearly all automotive applications where fibrous board structures are specified. 3.2.2 Paperboard 3.2.2.1 Description A generic term for a sheet manufactured primarily from cellulosic fibers pro
12、duced by conventional pulping and paper making process and equipment. 3.2.2.2 Physical/Mechanical Properties Except for the characteristic fibrous structure, the physical properties may vary over a wide range. The paperboards are anisotropic with the board machine direction having greater strength a
13、nd dimensional stability. 3.2.2.3 Applications The normal uses for this material include nearly all automotive applications where fibrous board structures are specified. 3.2.3 Chipboard 3.2.3.1 Description A general term describing a type of fiberboard produced primarily from mixed grades of waste p
14、aper and most often produced on a cylinder machine. The final product may be sold as either a single ply or laminated board. 3.2.3.2 Physical/Mechanical Properties The material is usually characterized by low density and gray color and is used where strength and quality are not required. The final p
15、roduct may be modified by the addition of nonfibrous components to impart water resistance or other special properties. The normal range of thickness is from about 0.23 to 1.14 mm (0.009 to 0.045 in) for single ply and 1.27 to 5.08 mm (0.050 to over 0.200 in) for laminated constructions. 3.2.3.3 App
16、lications Used in applications where appearance and ultimate strength are not important. Typical uses include visor cores, trim panel subfoundations, and some gasket applications. SAE INTERNATIONAL J947 Reaffirmed JAN2014 Page 3 of 5 3.2.4 Laminated Board 3.2.4.1 Description A general term describin
17、g a board comprised of two or more single plies of board, paper, or other sheet materials in any combination, firmly adhered to each other by means of an adhesive between the plies. The adhesion and cohesion of the entire finished structure are such that it will function as a single unit. 3.2.4.2 Ph
18、ysical/Mechanical Properties Except for the multiple structure, the physical characteristics of laminated boards vary over a wide range of properties. Because of the general nature of the term, there are few typical physical characteristics. 3.2.4.3 Applications Typical uses include head liners, tru
19、nk liners, glove boxes, and door panels. 3.2.5 Wet Machine Board (Homogeneous) 3.2.5.1 Description This material is produced on a one cylinder wet machine. It is manufactured by the building up on a roll of a number of wet plies of paper stock (refined cellulose fibers) from a continuous web. The we
20、t plies adhere mechanically to one another in the wet state and, when the desired thickness of board has been reached, the wet stock (approximately 40% solids) is removed from the make roll as a sheet. It is then pressed, dried, and calendared to the desired finished thickness. The pressing and dryi
21、ng operations develop strong fiber-to-fiber chemical and mechanical bonds within the plies and between the ply interfaces. 3.2.5.2 Physical/Mechanical Properties This board is characterized by high density stiffness and strength. This material is commonly produced in calipers ranging from a minimum
22、of 1.27 mm (0.050 or 0.060 in) up to a thickness of 25.4 mm (0.500 to 1.0 in) for various applications. This material frequently contains nonfibrous components such as resins or asphalt to develop water resistance, formability, or other special properties. 3.2.5.3 Applications Typical uses include t
23、acking strips and dash insulators. 3.2.6 Kraft Paper 3.2.6.1 Description Kraft is the generic name for paper of high strength which identifies the sulfate chemical pulping process from which the paper is made. The sulfate pulping process involves cooking wood fibers in an alkaline medium to produce
24、strong, cellulosic fiber which is normally converted to paper on a Fourdrinier paper machine. 3.2.6.2 Physical/Mechanical Properties The term paper is normally restricted to materials 0.23 mm (0.009 in) or under in caliper and usually less than 127 g/m2(26 lb/1000 ft2). The kraft paper is characteri
25、zed by a reddish-brown color in the unbleached state, but may be bleached to a very high brightness white for some applications. This material normally has high strength and is relatively dense. 3.2.6.3 Applications Uses include wire wrapping, braided insulators, liner for laminated fiberboards, and
26、 water shields. SAE INTERNATIONAL J947 Reaffirmed JAN2014 Page 4 of 5 3.3 Fiberboards Classified by Manufacture 3.3.1 Foundation Board 3.3.1.1 Description A fiberboard, usually a hardboard or a laminated kraft paper board, that is used as a structural foundation or a supporting member in a trim pane
27、l assembly. 3.3.1.2 Physical/Mechanical Properties Boards selected for foundation applications generally require a high degree of strength, rigidity, and dimensional stability; hence, most foundation boards are specified in thicknesses of 2.03 mm (0.08 in) or greater. Various applications may requir
28、e this board to be coated to facilitate dielectric bonding or to be painted, embossed, or perforated for decorative purposes. 3.3.1.3 Applications Typical applications include door and rear quarter panels, package tray panels, and headlining applications. 3.3.2 Subfoundation Board 3.3.2.1 Descriptio
29、n A fiberboard or liner used as a subfoundation in combination with a foundation board. It is used as a carrier for subsequent trim or product applications. 3.3.2.2 Physical/Mechanical Properties These boards are often chosen for their flexibility and as a result caliper usually ranges from 0.25 to
30、0.76 mm (0.010 to 0.030 in). In some cases, the boards may be coated to facilitate dielectric bonding. They are usually characterized by medium strength, good plybond, good dimensional stability, and are usually treated for water resistance. 3.3.2.3 Applications Typical automotive uses are in conjun
31、ction with door panels and rear quarter panels. 3.3.3 Forming Board 3.3.3.1 Description A board suitable for shallow forming or forming into random three-dimensional shapes through the use of heat and pressure applied in a matched set of dies. This board may be one ply or a laminated combination of
32、basic boards or a molded fiber pulp product. 3.3.3.2 Physical/Mechanical Properties The primary composition of these boards is normally refined cellulosic fibers which may or may not be supplemented by the addition of some synthetic fibers. Usually these boards contain various amounts of thermoplast
33、ic or thermosetting resins to facilitate formability and to enhance the stability and rigidity of the formed part. Normal thicknesses range from about 1.78 to 3.05 mm (0.070 to 0.120 in). 3.3.3.3 Applications Used in parts requiring three-dimensional shapes with rounded corners, such as formed arm r
34、ests, heater ducts, firewall components, and package trays. SAE INTERNATIONAL J947 Reaffirmed JAN2014 Page 5 of 5 3.3.4 Bending Board 3.3.4.1 Description A paperboard, either single ply or laminated, the components of which are comprised primarily of refined cellulosic fibers. 3.3.4.2 Physical/Mecha
35、nical Properties This material is constructed in such a way that the liner or liners are capable of accepting a suitable score and can later be bent on this score to varying degrees with little or no fracture of the surface fibers. This requirement is usually satisfied by using relatively long, stro
36、ng fibers on the bending surfaces. In some cases, the visual requirements of the bent scores are obtained by covering the surface with an extensible coating or by laminating a pliable film to the surface, prior to scoring and bending. Thickness is usually confined to the 0.41 to 2.54 mm (0.016 to 0.
37、100 in) range. 3.3.4.3 Applications Typical applications include scored glove boxes, package trays, visors, and trunk liners. 3.3.5 Properties 3.3.5.1 Creasing Method of scoring without cutting. See definition of scoring, paragraph 3.3.5.3. 3.3.5.2 Bending The folding movement applied to fiberboard,
38、 usually along impressed or cut scored lines. See definition for scoring, paragraph 3.3.5.3. 3.3.5.3 Scoring The method by which fiberboard may be depressed, or partially cut in basically linear configurations in any direction, which will later facilitate bending along the depressed or cut scores in
39、to various three-dimensional shapes. 3.3.5.4 Sizing Sizing is a broad term referring to the resistance of fiberboard to the penetration of liquids and to the process and chemicals for developing this resistance. Surface sizing (surface application) and beater sizing (internal application) are the me
40、thods of applying the sizing materials. 3.3.5.5 Cohesive Strength The tensile strength required to fracture internal bonds with the force applied perpendicularly to the plane of the board. Also referred to as Z direction tensile or plybond. 4. NOTES 4.1 Marginal Indicia A change bar (I) located in t
