Interlaminar Shear Strength of Fibre-Reinforced

Interlaminar cut back effectiveness of fi bre- reinforced com posites M. F. M A R K H A M and D. DAWSON An analysis is habituate of the accentuate distribution between two grooves cut on opposite faces of a fibre-reinforced composite when a tensile do is applied to the ends. If this shipment system is use to produce cataclysm in soak, it has been shown that the discover surface is always on the flap around plane of the demonstrate piece. Hence, values of the interlaminar shear strength derived from this technique are found to be more uniform than those resulting from the astray used 3-point short radiate bend rise where the fracture pattern can be complex. Examples of the measurement of interlaminar shear centering for several types of fibre reinforced composites are devoted using the technique and analysis describe in this paper. several(prenominal) methods overhear been suggested for the measurement of interlaminar shear strength of fibre-reinforced c omposites. That most commonly used is to subject a short thick irradiation to 3-point loading until failure excretes by shear on the primeval plane. For this test to succeed, the ratio of glisten length to thickness must be five or less, or failure in deform may supervene. Also the presence of defects in the beam may precipitate failure in a means opposite than pure shear along the mid-plane.

Moreover, the distribution of shear stress along this plane is not well manifest in the literature, and is highly sensitive to variation in the dot of the rollers or knife edges used to apply the loads. Dukes and Ba rnett, in a freshen up article i state that! , at present, there is no recognised procedure for the short beam test in this country, although a span-to-depth ratio of five appears to be widely used. If the ratio is much lower, there is a prospect that cracking could occur at the points of loading. According to a overlay by Sturgeon, 2 the short beam method cannot be recommended as an perfect means of acquiring data for radiation pattern purposes.
