Particle comprising a matrix and a radical initiator
The invention pertains to a particle comprising a composition containing a matrix and a peroxide or azo radical initiator, wherein the particle is a fiber or fibrid selected from aramid, polyester, polyamide, cellulose, and glass. The invention further relates to particle-elastomers comprising said composition, and skim products, tires, tire treads, and belts comprising these particle-elastomers.
The invention pertains to a double hopper system, comprising a first hopper (1) and a second hopper (2), the first hopper (1) has a first and a second opening (4; 5) and the second hopper (2) is arranged overhead the second opening (5) of the first hopper (1) and extend into the second opening (5) of the first hopper (1), the first opening (4) of the first hopper (1) has a length (I) and a distribution area (o), the second hopper (2) is movable arranged regarding the first hopper (1), whereby the second hopper (2) is movable over at least 3/4 of the length (I). The invention pertains also to a method for distributing material using a double hopper system.
A ballistic resistant article is presented comprising a plurality of fibrous layers, each of said layers comprising a network of fibers, wherein the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07 and a matrix material, wherein the matrix material comprises a mixture comprising: at least one styrene butadiene random copolymer resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without a tackifier the article according to the invention comprises a higher adhesion between the fibrous layers both in the unaged and aged state and a lower water pick up after water soak. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack. In contrast an article of the same construction but with a matrix material without the styrene butadiene random copolymer resin exhibits (very strong) interior delamination of the fibrous layers and the article of the same construction with the styrene butadiene random copolymer resin, but without the tackifier as the matrix material exhibits light delamination.
A ballistic resistant article is presented comprising a plurality of fibrous layers, each of said layers comprising a network of fibers, wherein the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07 and a matrix material, wherein the matrix material comprises a mixture comprising at least one self-crosslinking acrylic resin and/or at least one crosslinkable acrylic resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without tackifier the article according to the invention comprises a higher adhesion between the fibrous layers both in the unaged and aged state and a lower water pick up after water soak and the article passes the gasoline soak test. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack, whereas an article of the same construction but with a matrix material without tackifier exhibits interior delamination of the fibrous layers.
