In-Plane Shear Testing of Reinforced Plastics - ASTM D 3846

"Standard Test Method for In-Plane Shear Strength of Reinforced Plastics"
ASTM D 3846 is used to determine the in-plane shear strength of reinforced thermosetting flat sheet plastics in thicknesses ranging from 2.54 to 6.60 mm (0.100 to 0.260 in.).

In-plane shear strength is the shear strength at rupture in which the plane of fracture is located along the longitudinal axis of the specimen between two centrally located notches machined halfway through its thickness on opposing faces.

Shear tests of various kinds are widely used in the reinforced plastics industry to assess the strength of the reinforcement-to-resin bond in polyester, vinyl ester, and epoxy-resin composites.
