2.4. Coefficient of linear thermal expansion (CLTE)

Table 4, Table 5 presents CLTE data (two cycles). Data shows that increasing rWTB content decreased CLTE for both untreated composite and modified with MAPE composite. The addition of MAPE did not alter the behavior of the CLTE. CLTE data for rWTB blending with pine show that by increasing the rWTB content from 0% to 75%, CLTE increased. However, when this increased to 100%, CLTE started to decrease. Data indicates that MSS had no significant influence on CLTE of composites, and that simply decreasing MSS increased CLTE slightly [1].
