Predicting Flexural Strength of Additively Manufactured Continuous Carbon Fiber-Reinforced Polymer Composites Using Machine Learning

Journal of Computing and Information Science in Engineering, 2020
Carbon fiber-reinforced polymer (CFRP) composites have been used extensively in the aerospace and automotive industries due to their high strength-to-weight and stiffness-to-weight ratios.

Flexural strength of rebased denture polymers

Journal of Oral Rehabilitation, 2000
The properties of denture base and reline resins may be affected by daily changes between room temperature and mouth temperature. The purpose of the study was to evaluate the effect of thermocycling on the flexural strength of the relined denture base polymer with reline resin.

Flexural strength of provisional restorative materials

The Journal of Prosthetic Dentistry, 1993
A provisional restorative material must be strong enough to resist fracture during function. This study tested five autopolymerizing provisional resin materials under conditions that related the stresses acting on them to those acting on a fixed partial denture.

The flexural strength of concrete blockwork

Magazine of Concrete Research, 1980
Synopsis The results of a large number of flexural strength tests on wallettes (small masonry panels for testing) made with a range of commercially available concrete blocks are reported. The relationships between the performance of the wallettes and several properties of the block were investigated as a possible basis for a table of characteristic ...

Flexural Strength of Float Glass

Applied Mechanics and Materials, 2015
A series of simple and laminated glass tests were carried out under laboratory conditions at the Klokner Institute. The test specimens comprised panes made from float glass with dimensions of 1.1 x 0.36 m. The paper contains experimentally determined characteristic values of flexural strength and estimated design values related to commonly used glass.

Flexural strength and porosity of cements

Nature, 1981
A curious feature of hydraulic cements, such as those based on calcium silicate, calcium aluminate and calcium sulphate, is that they exhibit similarly low flexural strengths, typically between 3 and 10 MPa, despite their differing chemical composition, varying degrees of hydration and contrasting setting mechanisms1–3.
