pls answer when u know about dis question //
*Resins made from a combination of macrofill and microfill particles that are generally considered easy to polish and highly resistant to fracture and wear. They may be used for either anterior or posterior applications.
*The hybrid composites offer advantages regarding structural integrity and sustained load under crash and impact conditions.
Natural fabric-based thermoset composites are generally lower in strength performance compared to hybrid composites. However, they have the advantages of design flexibility, cost effectiveness, lack of health-hazard problems and recycling possibilities.
Hybridization with some amounts of synthetic fibers makes these natural fabric composites more suitable for technical applications such as automotive interior parts.
*There are several types of hybrid composites characterized as: (1) interply or tow-by-tow, in which tows of the two or more constituent types of fiber are mixed in a regular or random manner; (2) sandwich hybrids, also known as core-shell, in which one material is sandwiched between two layers of another; (3) interply or laminated, where alternate layers of the two (or more) materials are stacked in a regular manner; (4) intimately mixed hybrids, where the constituent fibers are made to mix as randomly as possible so that no over-concentration of any one type is present in the material; (5) other kinds, such as those reinforced with ribs, pultruded wires, thin veils of fiber or combinations of the above.
