If you like to setup a quick demo, let us know at support madcad. Have a question about conducting the test for this standard? Under certain application conditions, the system may be placed entirely by hand methods assuring a uniform, even final appearance.
The force capacity and maximum strain measurements are based solely on test specimens that fail in the gauge section. The composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. Therefore, maximum force and strain data associated with failure or pullout d765 either grip are disregarded.
ASTM R7565 can be used to obtain the tensile force capacity and ultimate tensile strain of FRP material used for the strengthening of other structural materials such as, metals, timber, and reinforced concrete. The Engineer of Record may suspend the work if the Contractor substitutes an unapproved FRP system or unapproved personnel during construction.
Section 03 01 Only epoxy resins will be accepted for construction of FRP systems referenced in this specification. D Terminology for Composite Materials.
ASTM D describes wstm requirements for sample preparation, tensile testing, and results calculation of flat fiber reinforced polymer FRP composite materials used for the strengthening of structures made of materials such as metals, timber, masonry, and reinforced concrete. Documents Flashcards Grammar checker. Additional tests may be performed to qualify the work at each identified area.
Filling of large voids in surfaces to receive composite shall be paid as an extra to the contract work of installing the composite system small pinholes or micro-bubbles in the satm surface or resin do not require special detailing.
Well-adhered paint and concrete do not require removal. No items in cart. ASTM D may be used to determine the tensile properties of wet lay-up and pre-impregnated FRP composites fabricated on site or manufactured in a factory setting. The method may be used to determine the tensile properties of wet lay-up and pre-impregnated FRP composites fabricated on site or manufactured in a factory setting.
The method only covers the determination of the tensile properties of the FRP composite material. Strengthening of Cast-in-Place Concrete Section 03 01 Within the text, the inch-pound units are shown in brackets. We are confident that we have what you are looking for.
ASTM D7565 Tensile Properties of FRP Matrix Composites for Civil Structures
The locations of the pull-off tests shall be representative and on flat surfaces. Register for a trial account. The obtained tensile properties can be used for material specifications, quality control and assurance, structural design and analysis, and research and development.
The composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. Complete report and submit to Owner, engineer-of-record and FRP composite system manufacturer.
Fill surfaces with thickened epoxy to eliminate air surface voids greater than 0. Combining values from the asttm systems may result in nonconformance with the standard. 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 d75565 use.
Cover with plastic film and squeegee out asttm bubbles. Provide anchorage as detailed on construction drawings, if required. If finish is provided beyond 72 hours of the application of the epoxy, the surface must be roughened by hand sanding or brush blasting, prior to finishing.
Certified applicators shall have the minimum experience and written consent by the FRP manufacturer See Section 1. Leave the site clean. Pre-faced Concrete Unit Masonry. Are you sure you want to empty the cart?
Link to Active This link will always route to the current Active version of the standard. Other components used to attach the FRP material to the substrate, such as the primer, putty, and adhesive in externally bonded strengthening systems, are excluded from the sample preparation and testing detailed in this document. If moisture is present, use the manufacturer suggested wet astmm epoxy, if available. Review project specifications in detail. The certified applicator shall prove a minimum of 5 years experience in performing retrofits using FRP systems and submit a list of no fewer than 15 successful installations.
If all tested samples of the sample batch do sstm meet the conditions of acceptance, it is recommended that 25 percent of all samples be tested.
Other components used to attach the FRP material to the substrate, such as the primer, putty, and adhesive in externally bonded strengthening systems, are excluded from the sample preparation and testing detailed in this document.

Remember me for one month. The method may be used to determine the tensile properties of wet lay-up and pre-impregnated FRP composites fabricated on site or manufactured in a factory setting.
Acceptable minimum values for ultimate tensile strength, tensile modulus, and elongation shall not be below the submitted design values unless calculations are performed using the tested values that exhibit an acceptable capacity as per the original design demands and concept.
All defective areas shall be repaired as per Section 3. They shall be manufactured and shipped directly from the manufacturer. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
Where a date is given for referenced standards, the edition of that date shall be used. Tests shall be performed on each type of substrate or for each surface preparation technique used. The prepared, identified samples shall be given to a pre-approved and experienced testing laboratory.
Any batch that exceeds the batch life shall not be used.
