mechanical properties of wood polymer composites

the ability of a wpc to resist deformation under load is defined as flexural strength and three-point static bending test, astm d790, is a usual procedure to measure this property as shown in fig. 5.3. in this test geometry, the wpc sample experiences compressive stress at the load-bearing side and tensile stress at the opposite end.

switch matrix theory. image 1 is the switch matrix from an addams family. the wire color, board connector and pin, and the ic or transistor identifier are provided for each row and column. so for any switch we can move left across the row to get the return side info and up the column to get the send or strobe side info.

polymer matrix composites

polymer matrix composites consist of thermoset or thermoplastic matrix resins reinforced by fibers that are much stronger and stiffer than the matrix. polymer matrix composites are attractive because they are lighter, stronger, and stiffer than the unreinforced polymers or conventional metals, with the additional advantage that their properties and form can be tailored to meet the needs of a specific application.
