Overview
ISO 10371:1993 specifies the basis for the specification of braided tapes used as reinforcement materials in plastics. This international standard is applicable to tapes braided from all types of yarn or roving, including glass, carbon, aramid, ceramic fibers, and hybrids. It covers important aspects such as designation, characteristics, defects, sampling, test methods, packaging, and ordering requirements. The standard ensures consistency and reliability in the specification and use of braided tapes in composite manufacturing, providing detailed guidance on their properties and quality control.
Key Topics
-
Scope and Definitions
ISO 10371:1993 applies to braided tapes used as reinforcements in plastics, defining key concepts such as braided tape, braiding method, construction, carriers, and braid angle.
-
Designation and Description
Braided tapes are designated using a code made up of fiber types, tape width (mm), mass per metre (g/m), and braid angle (degrees). The standard defines how to interpret and generate these codes based on measured physical properties.
-
Characteristics and Defects
The standard outlines criteria for tape uniformity, permissible defects (such as ends out, tight or slack ends, angle deviations), and treatment types (textile size, plastic size, desizing, coupling finish). Defects like dirt, folds, grease, holes, and faulty splices are also identified for quality control.
-
Sampling and Testing
Detailed procedures include sampling from batches, selection of test specimens, and conditioning under standardized atmospheres (23°C ± 2°C, 50% ± 5% relative humidity).
Key test methods outlined include:
- Measurement of thickness per ISO 4603
- Determination of width, braid angle, and mass per metre length through specified apparatus and calculation formulas
-
Packaging and Ordering
Recommendations for packaging to maintain quality during storage are specified. Ordering details include referencing the standard, desired quality, braid type and angle, fiber type and number of carriers, roll mass, and tape designation codes.
Applications
ISO 10371:1993 is critical for industries where braided tape reinforcements are used, including:
- Production of composite plastics and reinforced materials
- Aerospace and automotive manufacturing where high-performance reinforced plastics are essential
- Sporting goods and construction materials requiring reinforced composites
- Quality assurance and supplier communication for consistent braided tape specifications
By standardizing terms, measurement methods, and quality requirements, this ISO standard facilitates reliable integration of braided tapes in composite materials, ensuring product performance and durability.
Related Standards
ISO 10371 references and complements several other standards relevant to textile and composite reinforcements:
- ISO 2797 & ISO 3598: Specifications for textile glass rovings and yarns
- ISO 1886: Sampling plans for reinforcement fibers
- ISO 4603: Measurement of fabric thickness
- ISO 291 & ISO 139: Standard atmospheres for conditioning and testing
- ISO 1887: Determination of combustible matter content in textile glass
- ISO 10120: Determination of linear density of carbon fibers
Together, these standards provide a comprehensive framework for managing the design, testing, and quality of braided reinforcement materials used in advanced composites.
