The purpose of this study was to compare the load-to-failure of different common suturing techniques with a new technique for the medial meniscus posterior root tear (MMPRT).Thirty porcine medial menisci were randomly assigned to three suturing techniques used for transtibial pullout repair of the MMPRT (n = 10 per group).

Abstract The cure times (t90), tensile strengths and tear strengths of silica-filled epoxidised natural rubber (ENR), with or without the presence of γ-mercaptopropyltrimethoxysilane (A-189) and bis(triethoxysilylpropyl) tetrasulphide (Si-69) and cure using a semi-efficient vulcanisation (semi-EV system) were studied.

Relationship of Tensile and Tear Strengths of Fabrics to Component Yarn Properties
1970Abstract : The investigation was conducted on six selected fabrics to determine the relationship of breaking load, elongation and tear strength of fabrics to the properties of the component yarns. A system for expressing fabric properties as ratios of the contributing yarn properties was developed.

AbstractAt any given crosslink density, the ultimate tensile and tear strengths of vulcanizates depend on the curing system and decrease in the order: conventional (CV) > efficient (EV) > peroxide > radiation cured. Measurements on three network parameters were interpreted as indicating that crosslinks were not uniformly distributed throughout

Fillers play important roles in enhancing mechanical properties of NR latex films. The effect of filler dispersion and amount of dispersing agent to the tensile strength and tearing energy of NR latex films were investigated in this study. The studies were carried out by (i) varying the amount of dispersing agent (Anchoid) added which is an anionic ...

Abstract A study has been made of the cure times (t90), the tensile strengths and the tear strengths of silica-filled NR, NBR and SBR, with and without the presence of γ-mercaptopropyltrimethoxysilane, (MPTS) and cured using the semi-efficient vulcanization system (semi-EV). Mixing was done using a Brabender Plasti-corder having a mixing cam attached

Abstract A black-filled styrene-butadiene rubber (SBR) vulcanizate was ambiently ground, then used as an additive to the original, uncured compound. Sheets of the resulting composite (matrix/ground rubber particulate) were cured, and tensile and trouser tear strength determined.

Abstract The effects of crosslink density and crosslink type on the tensile and tear strengths of gum NR, SBR and EPDM vulcanizates have been studied. Over a wide range of crosslink densities, sulphur vulcanizates for these rubbers have higher strengths than the peroxide vulcanizates. These results show that crystallizability of the rubbers is not an
