Пластичне масе – Одређивање затезних својстава – Део 6: Мерење дистрибуције деформација за насумично оријентисане пластичне композите ојачане исецканим нитима или влакнима

Plastics - Determination of tensile properties - Part 6: Measurement of strain distribution for randomly oriented chopped strand- or fibre- reinforced plastic composites (ISO/DIS 527-6:2026)

Апстракт

This document specifies measurement method of strain distribution for randomly oriented chopped strand- or fibre- reinforced plastic composites, based upon the general principles given in ISO 527-4. The methods are used to evaluate the inherent dispersion of strain properties and investigate the in-plane statistical material properties of the test specimens. The main purpose distinguished from the existing standards is to understand strain distribution due to randomly orientation of chopped fibre, while ISO 527-4 is sufficient for evaluating only the macroscopic elastic modulus.
